“Phenomena exist in the material world. Material makes thoughts tangible. Materials manifest the world. Being a [designer] means being an intermediary, the connecting link between ideas and materials. This role of a go-between requires more than simple enquiry, it requires solid investigation and research: an exploration of what can be coaxed out of materials, what can be added, what the materials can support, what they can hide, what they can emit, what they can keep what they can simulate, and in the ﬁnal instance, what they can create and what they can destroy.”

OVERVIEW JONSARA RUTH

“Materials manifest the world...” TRAshell panels are manufactured through a closed moulding process from free-oriented short natural ﬁbers, and a plant-based thermoset bioresin.

“Atmosphere” of a space can be described as the feeling of a place. “Atmosphere” can also describe the air quality of a place. In both definitions, the atmosphere of interiors is largely dependent upon its materiality. Materials constitute our physical environments and influence how we experience the world, how we navigate the world, and how we design the world. Material literacy is fundamental for every designer. This course provides students not only with a comprehension of the large variety of materials most commonly used in design and the performance of each of them, but also to establish design literacy with materials – how to use them in sensitive, innovative and appropriate ways, and how to evaluate them for their impact on human and environmental health. Acquiring material literacy requires examining materials from a variety of perspectives with curiosity. In this course students gain knowledge about materials for design by engaging with them in multiple ways for the duration of the semester. Jonsara Ruth, Design Director of Healthy Materials Lab and Associate Professor of Interior Design, rewrote the Materials & Performance Course for MFA Interior Design in order to bring conscious and direct attention to the impact that materials in the built environment have on people’s health and on the overall health of the planet. The course re-development was supported by Healthy Materials Lab (HML) at Parsons and co-taught with Assistant Professor, Yu Nong Khew and HML design researcher, and part-time faculty member, Sam Bennett. All MFA Interior Design students are required to take this course in their first semester. The student work published in this booklet is authored by students in the Fall of 2017, 2018, and 2019. This booklet gives an overview of the content developed and researched by faculty and students in the Materials & Performance course, using the lenses of human health and environmental health to study materials for design.

Photo journals reveal student's evolving insights: Over the course of the semester, students are asked to create a habit of noticing materials in the built environment and recording these observations in a photographic journal. Materials are photographed in context, noticing differences in color, tone, texture and quality; how people interact with materials; how the weather has altered the material; and countless other insights. We ask that students remain curious, bringing attention to looking closely at materials and reﬂecting insights in their photographs. Every post is an original photograph. We use the platform of Instagram to share observations of materials with each other. #parsonsmfaidmaterials Research about materials’ particular qualities and performances: Students are expected to deeply research one of the assigned material topics and present their discoveries to the class. The goal is to discover, reveal and communicate histories, cultures, processes, human impacts, and environmental impacts related to each material. They bring physical samples from the Donghia healthier Materials Library to illustrate their research. Students are encouraged to present their research through creative, visual storytelling.

Experimenting with materials as empirical research: Students are expected to research deeply through making with assigned material types. Students presented to the class their experiences about techniques, machines, and experiments used in the process of making. For these experiments, each raw material was required to be in 8”x 8” pieces. Students are encouraged to radically transform 8-10 pieces of that material and to document all processes of making. Students were expected to research deeply one of the assigned material topics and present about their ﬁndings. The goal was for them to discover, reveal and communicate histories, cultures, processes, human impacts, and environmental impacts related to materials. They presented their research through slides or video and oral presentation. They also brought physical samples from the Donghia healthier Materials Library to illustrate their research. And they used other means of creative presentation or storytelling. This research seminar looks deeply into materials used to design environments. From the structural to the decorative, all materials are viewed for their impact on the environment and on human health; for their historical and cultural meaning; for their physical performative qualities and for the way in which material choices affect human experience and the character of interior space.

Of 30 million types of materials on the planet, we concentrate on a few basic material categories: Natural, Recycled, Synthetic and Soft. Each week we concentrate on the most commonly used building materials, including wood, stone, metal, cementitious, textiles, glass, clay, plastics, textiles, as well as composite biofabricated and recycled materials. We relentlessly ask: Where did the material come from? How and where is it made? What are the ingredients that compose this material? How is it processed? What are its effects or impacts on interior air? Where does it go at the end of its useful life? The fundamental goal is to nurture a habit of noticing the qualities of materials and critically ask questions about their composition and how they impact human health and the environment. With this understanding, students will develop a practice of design with an inherent commitment to sustainability. The course is structured as part lecture, part research lab, and part fieldwork. Students engage in material research throughout the semester - alternating between studying a material’s origins, its impact in socio-political contexts, on culture and on people with experimenting and manipulating physical material samples. Students discover historical applications, current fabrication methods and new technologies. Through making, they learn with their hands about a material’s substance and its performative qualities while exploring with critical awareness. Through rigorous exploration, curiosities are nurtured to imagine a wide range of applications for materials. All research, including unexpected outcomes or failed experiments, are documented and presented to the class for discussion. Throughout the semester students develop a keen sense of observation for materials, their applications around us in the city, and how they relate to light, sound and human behavior. Keeping a photo journal is required not only to share observations with the class, but also to nurture a practice of noticing materials in the built environments which surround us. A series of lectures focusing on specific materials are augmented by field trips to observe material showrooms, fabrication shops, and recycling centers. Ultimately, this course offers an understanding about how to think about materials, how to evaluate them for their impacts on people and environments, how to explore them, and how to understand their useful applications, their histories and their cultural meaning.

MATERIAL WASTE 2

Beginning with the end in mind... "Human beings extract about 15 billion tons of raw material—that's 30 trillion pounds—from the earth each year, and from that they make every kind of stuff that you can ﬁnd in every kind of thing. Mined ore becomes metal becomes wire becomes part of a motor becomes a cooling fan in a computer. Harvested wood becomes lumber becomes a home. Drilled petroleum becomes chemical feedstock becomes synthetic rubber becomes automobile tires. Natural gas becomes polyethylene becomes milk jugs and oversized, multicolored yard toys. Mined silica sand becomes silicon crystal becomes the base of microelectronic chips. Each kind of stuff is a link to enormous industrial trains whose workers process the world's raw materials into usable forms that constitute the items of our constructed landscape. Each kind of stuff also is a palimpsest of innovations in the use of materials, some going back to prehistoric times. The wood-pulp paper from which books are made today comes from wood-pulp paper from which books are made today comes from a pedigree of cotton and linen rags, animal-skin parchment, Nile-reed papyrus, and Sumerian clay tablets. The ink, a black pigment made from the ground ash of some carbon-bearing fuel and then suspended in a rapidly evaporating solvent, has its roots in crushed ore and charcoal mixed with spit or animal grease for use on cave walls and faces. The materials in every book tell a tale that rivals the one conveyed in its words.

Edward Burtynsky, Oxford Tire Pile #4, Westley, California, USA, 1999

It is the same for every other material thing that you encounter. Train your attention on the stuff of things rather than on their function. What you see is a rich medley of materials: the liquid crystal display of your laptop computer; the gritty concrete sidewalk on which you are strolling; the nylon of your raincoat's zipper; the carbon-fiber-reinforced epoxy polymer of your tennis racket; the Kevlar polymer in your police force's bullet-proof vests; the oak of your dresser; the diamond in your engagement ring; the nickel-based superalloy in the turbine blades in the engine of an airliner you are flying in; the warm, supple skin of your newborn; the cool, transparent glass of your office window; the combination of slick, high-density polyethylene and stainless steel that make up the artificial hip which a surgeon may have implanted into you; the cotton of the shirt you are wearing; the aluminum of the can you just drank from. In a single day the thousands of man-made materials that you encounter, engage, manipulate, and use display a diversity every bit as wondrous as that found in living organisms, which are composed of the most miraculous of all the world's materials—skin, bone, tendon, muscle, nail, hair, and scads of other biological tissues—all of them honed by evolutionary engineering into a beautiful marriage of form and function. That books and buildings and the things in the world are supposed to be made of materials suited for their functions is so obvious that it almost goes without saying. But things that go without saying long enough are readily forgotten. That is why the materials that make up the world are most often not on people's minds." Ivan Amato, "Introduction", Stuff, 2-3.

What is in the air we breathe indoors? Indoor air can be approximately 2-3 times more harmful than outdoor air. 2

MATERIAL HEALTH Homefront Where We're Exposed Everyday The interior air we breathe is polluted by common household items. In addition to exposure through inhalation, these toxic chemicals permeate our bodies through ingestion (food or hand-to-mouth) and through our skin. Potential effects to our health from daily exposure include:

Hormone Disruption, Nervous System Disorders, Immune System Suppression,

Reproductive Challenges, Infertility Issues, Diabetes, Obestity, Cancer

Children and developing fetuses are particularly vulnerable to both exposure and its long-term effects. Children spend more time on the ﬂoor, where toxins and contaminants (e.g., dust) commonly settle. Chemicals of concern can pass from a mother to a developing fetus through the placenta. (See page 69, "Material Health" for resources about fetal transfer, children and toxins.) A 2018 study by the Environmental Working Group found 287 chemicals in the umbilical cord blood of 10 US newborns; environmental exposure to these chemicals (which come by way of industrial chemicals, consumer product ingredients, pesticides, and burning coal) is linked to increase in childhood diseases including:

Birth Defects Autism Preterm Birth Asthma Neuro-developmental Disorder Childhood Cancer

Reframing Good Design is Healthy Design As students prepare to design interior constructed environments, its important that they do not build with harmful materials. Awareness and knowledge about material health begins with learning to rigorously ask questions, including:

What is it made of? How is it made? Where is it made? Does it require ﬁnishes?

How will it be installed? Who will be exposed? What are the health vulnerabilities of occupants?

TOXIC PRODUCTION 4

UNITIES 6 IN YOUR NEIGHBORHOOD? “Today, zip code is still the most potent predictor of an individual’s health and well-being. Individuals who physically live on the 'wrong side of the tracks' are subjected to elevated environmental health threats and more than their fair share of preventable diseases.” Dr. Robert Bullard, "The Father of Environmental Justice"

The Times analysis looked at sites listed in the federal Toxic Release Inventory, which covers more than 21,600 facilities across the country that handle large amounts of toxic chemicals harmful to health or the environment. Of those sites, more than 1,400 were in locations the Federal Emergency Management Agency considers to have a high risk of flooding. An additional 1,100 sites were in areas of moderate risk. Other industrial complexes lie just outside these defined flood-risk zones, obscuring their vulnerability as flood patterns shift and expand.

Anchored in flood-prone areas in every American state are more than 2,500 sites that handle toxic chemicals, a New York Times analysis of federal floodplain and industrial data shows. About 1,400 are located in areas at highest risk of flooding.

The presence of chemical sites in areas vulnerable to ﬂooding is a holdover from an age where the advantages to industry of proximity to rivers and oceans — for transportation and trade, or for a ready supply of cooling water — seemingly outweighed the risks.

As ﬂood danger grows — the consequence of a warming climate — the risk is that there will be more toxic spills like the one that struck Baytown, Tex., where Hurricane Harvey swamped a chemicals plant, releasing lye. Or like the ones at a Florida fertilizer plant that leaked phosphoric acid and an Ohio reﬁnery that released benzene.

“Waterfronts are changing as a result of sea level rise,” said Jeanne Herb, an environmental policy expert at Rutgers University who has researched hazards posed by climate-related flooding to industries in New Jersey. “More often than not, these are facilities are on the water for a reason,” she said. “So how do we make sure that there are protections in place? That’s the big question.” Federal law does not explicitly require sites in floodplains that handle toxic chemicals to take extra precautions against flooding. Nor do most states or local governments have such requirements.

Flooding nationwide is likely to worsen because of climate change, an exhaustive scientiﬁc report by the federal government warned last year. Heavy rainfall is increasing in intensity and frequency. At the same time, rising sea levels combined with more frequent and extensive ﬂooding from coastal storms like hurricanes may increase the risk to chemical facilities near waterways.

More Than 2,500 Sites That Handle Toxic Chemicals Are Located in Flood-Prone Areas Across the Country.

WOOD

carbon 50% , oxygen 42%, hydrogen 6%, nitrogen 1%, other elements 1% (mainly calcium, potassium, sodium, magnesium, iron, and manganese)

Trees have been used throughout human history to provide a fundamental material for making buildings, furniture, objects, and interiors. Trees are a naturally growing plant which, when cut, milled, and dried, is called ‘timber’, ‘lumber’ or ‘wood’. Its relative softness makes wood a material that can be manipulated easily and its inherent structural properties allow it to last for hundreds of years. Trees also provide our planet’s most essential storage for carbon, making them a very important component for slowing climate change. Although many parts of the world have an abundance of trees, there is an increasing rate of deforestation. If deforestation continues, more carbon will be released damaging the atmosphere as well as putting forest habitats and biodiversity at risk.

FACULTY PRESENTATION From Trees to Timber

01. Debarking.

02. Debarking of wooden logs.

03. Timber.

04. Stacking lumber. Trees, one of our most ubiquitous and important natural resources, can be defined as “a woody plant that regularly renews its growth” (https://www.britannica.com/ plant/tree) Its renewable quality makes it a sustainable choice for design and architecture and its “woody” quality allows for its sturdiness and structural integrity. Living trees purify the air that we breathe and absorb large amounts of carbon dioxide from the atmosphere, which help our battle in the climate crisis. Yet, in the design field, these magnificent plants have a different name. Once they are harvested for use in fabrication and construction, trees are called “logs”, “wood”, “lumber” or “timber”. And once made into building products, trees might take different names such as “plywood”, “2x4”, or “plank”. The process of harvesting trees to become useful building materials has many stages and it is incredibly important that each stage is executed in a responsible manner. Responsibly managed forests require the careful consideration of timber harvesters. A forest is more than a large collection of trees - it is an ecosystem for living creatures and organisms. Silviculture is the art and science of controlling the growth of forests

08. Lumber ready to ship and be used.

to maintain ecosystems while allowing thinning so that trees can be used for timber production. Once cut, the tree, now called a log, will be transported to the saw mill where the bark is removed and the tree is cut. Depending on the ultimate use, it may be sawn into boards or rotary cut into veneer. The method of cutting requires experienced understanding so that the tree can be used to maximum capacity. There are many terms to describe the cutting including Quarter Sawn, Plain Sawn, or Live Sawn. The cut will determine the structure of the board, its ultimate strength, and the grain pattern.

05. Sawdust used as fuel for boiler.

Transforming a tree into usable material is an ancient art and science. Over the course of human history we have seen transformations of the earth and our atmosphere because of clearcutting of forests and other mismanagement of the planet’s tree growth. History has also shown the incredible development of human habitats, towns and cities, growing because of the use of trees for construction. And in our interiors we have long enjoyed the warmth of nature that is provided by bringing trees indoors as furniture, ﬂooring and wall covering.

Our dilemma in agriculture now is that the industrial methods that have so spectacularly solved some of the problems of food production have been accompanied by “side effects” so damaging as to threaten the survival of farming. Perhaps the best clue to the nature and gravity of this dilemma is that it is not limited to agriculture. My immediate concern here is with the irony of agricultural methods that destroy, first, the health of the soil and, finally, the health of human communities. But I could just as easily be talking about sanitation systems that pollute, school systems that graduate illiterate students, medical cures that cause disease, or nuclear armaments that explode in the midst of the people they are meant to protect. This is a kind of surprise that is characteristic of our time: the cure proves incurable; security results in the evacuation of a neighborhood or a town. It is only when it is understood that our agricultural dilemma is characteristic not of our agriculture but of our time that we can begin to understand why these surprises happen, and to work out standards of judgment that may prevent them. To the problems of farming, then, as to other problems of our time, there appear to be three kinds of solutions: There is, first, the solution that causes a ramifying series of new problems, the only limiting criterion being, apparently, that the new problems should arise beyond the purview of the expertise that produced the solution – as, in agriculture, industrial solutions to the problem of production have invariably caused problems of maintenance, conservation, economics, community health, etc., etc. If, for example, beef cattle are fed in large feed lots, within the boundaries of the feeding operation itself a certain factory-like order and efficiency can be achieved. But even within those boundaries that mechanical order immediately produces a biological disorder, for we know that health problems and dependence on drugs will be greater among cattle so confined than among cattle on pasture. And beyond those boundaries, the problems multiply. Pen feeding of cattle in large numbers involves, first, a manure-removal problem, which becomes at some point a health problem for the animals themselves, for the local watershed, and for adjoining ecosystems and human communities. If the manure is disposed of without returning it to the soil that produced the feed, a serious problem of soil fertility is involved. But we know too that large concentrations of animals in feed lots in one place tend to be associated with, and to promote, large cash-grain monocultures in other places. These monocultures tend to be accompanied by a whole set of specifically agricultural problems: soil erosion, soil compaction,

Solving for Pattern epidemic infestations of pests, weeds, and disease. But they are also accompanied by a set of agricultural - economic problems (dependence on purchased technology; dependence on purchased fuels, fertilizers, and poisons; dependence on credit) – and by a set of community problems, beginning with depopulation and the removal of sources, services, and market to more and more distant towns. And these are, so to speak, only the ﬁrst circle of the bad effects of a bad solution. With a little care, their branchings can be traced on into nature, into the life of the cities, and into the cultural and economic life of the nation.

WENDELL BERRY Chapter 9, in The Gift of Good Land: Further Essays Cultural & Agricultural define an agricultural problem as if it were solely a problem of agriculture – or solely a problem of production or technology or economics – is simply to misunderstand the problem, either inadvertently or deliberately, either for profit or because of a prevalent fashion of thought. The whole problem must be solved, not just some handily identifiable and simplifiable aspect of it.

Both kinds of bad solutions leave their problems unsolved. Bigger tractors do not solve the problem of soil compaction any more than air conditioners solve the problem of air pollution. Nor does the large confinement-feeding operation solve the problem of food production; it is, rather, a way calculated to allow large-scale ambition and greed to profit from food production. The real problem of food production occurs within a complex, mutually influential relationship of soil, plants, animals, and people. A real solution to that problem will therefore be ecologically, agriculturally, and culturally healthful. Perhaps it is not until health is set down as the aim that Detail of CACTUS by Gufram, 1972 Drocco / Mello we come in sight of the

The second kind of solution is that which immediately worsens the problem it is intended to solve, causing a hellish symbiosis in which problem and solution reciprocally enlarge one another in a sequence that, so far as its own logic is concerned, is limitless – as when the

problem of soil compaction is “solved” by a bigger tractor, which further compacts the soil, which makes a need for a still bigger tractor, and so on and on. There is an identical symbiosis between coal-ﬁred power plants and air conditioners. It is characteristic of such solutions that no one prospers by them but the suppliers of fuel and equipment. These two kinds of solutions are obviously bad. They always serve one good at the expense of another or of several others, and I believe that if all their effects were ever to be accounted for they would be seen to involve, too frequently if not invariably, a net loss to nature, agriculture, and the human commonwealth. Such solutions always involve a deﬁnition of the problem that is either false or so narrow as to be virtually false. To

third kind of solution: that which causes a ramifying series of solutions – as when meat animals are fed on the farm where the feed is raised, and where the feed is raised to be fed to the animals that are on the farm. Even so rudimentary a description implies a concern for pattern, for quality, which necessarily complicates the concern for production. The farmer has put plants and animals into a relationship of mutual dependence, and must perforce be concerned for balance or symmetry, a reciprocating connection in the pattern of the farm that is biological, not industrial, and that involves solutions to problems of fertility, soil husbandry, economics, sanitation the whole complex of problems whose proper solutions add up to health: the health of the soil, of plants and animals, of farm and farmer, of farm family and farm community, all involved in the same internested, interlocking pattern – or pattern of patterns.

Stone has been quarried and used in building structures for thousands of years. The vast varieties of stone reveal how they were formed in the earth through their speciﬁc properties. Igneous, metamorphic and sedimentary rocks were formed because of pressures and stresses from the earth. The most common stones used in building Granite (igneous), Marble (metamorphic) and Limestone (sedimentary) have widely different properties because of the way that they were formed and in which part of the planet they are found.

Earth , Air , Fire , Water IVAN AMATO Chapter 9, in Stuff One day about 2.5 million vears ago, a protohuman living in eastern Africa's Rift Valley made a momentous discovery. No one knows the details, but it could have gone something like this: During a search for rocks suitably sharpedged for scraping meat from bones, this hominid—either an Australopithecus or Homo habilus whom we shall call George— picked up a hunk of dark brown flint by a chalky cliff face. Finding it too dull, he threw it down, an exercise he and his kind had repeated a million times before. This time, however, it was different. The loud report of the stone hitting another stone drew George's attention. Right there at the point of impact lay just what he had been looking for—a sharp-edged flake the size of his palm. As George stared at this unbidden gift, his brows furrowed. A novel shiver of insight swept over his nearly human brain. Seizing another piece of flint, he once again struck rock against rock, and more sharpedged flakes laid themselves out in front of his discovery-widened eyes. In one stroke (George unwittingly launched the Paleolithic Age (the Old Stone Age) and invented materials engineering. Materials engineers are the people who figure out how to make the estimated fifty thousand materials that compose the modern industrial landscape, including the silicon crystals of computer chips, the ultrapure glass strands of optical fibers, the nickel-based superalloys of jet engines, and the synthetic rubber of car tires-none of which are found lying around in the wilderness. They are made the way George made his first artificial stone tool: by transforming the raw materials of the world into new and more useful forms. Before George's discovery, technology had always been the art of using things pretty much as they were found. A stick from a flat-topped acacia tree was good for getting at ants underneath the savanna's hard earth. A heavy, egg-shaped lava stone was good for hammering open wildebeest bones to get at the marrow-rich interiors. Left intact, the same bones were good for beating the daylights out of the living flesh of a rival protohuman. The Old Stone Age, which lasted until about fifteen thousand years ago, certainly also was the age of wood, bone, hide, leaf, shell, hoof, horn, tendon, tooth,

Above: Used in the Paleolithic era as handheld tools, this collection of burins was found in Brassempouy, France. tortoise shell, claw, vine, bark, sap, and of any other easily accessible material that proved useful in its raw form. George, our Paleolithic Edison, realized that hominids like him did not have to be satisfied with the world as they found it. Bashing one rock against another can get you a sharp cutting edge where there wasn't one before. And with a ready supply of sharp stone tools, George could scavenge more meat frorn recently killed prey in the little time he had before other scavengers like hyenas arrived "with their own lust for the same meat. Stone flaking meant larger and tougherskinned animals could be butchered, which made more of the world habitable. Early stone technology helped open doors out of Africa to Europe, Asia, China, and eventually to North and South America. George's discovery was worthy of a special Nobel Prize given every few hundred thousand years: a lifetime of premium flint to the winner. The technology of stone flaking, dubbed the first technology by some paleoanthropologists, probably spread quickly throughout George's own clan, and then more slowly to other clans. Toolmakers found that certain ways of hitting stones together produced more useful shapes and sharper edges; they found that materials like flint and obsidian (volcanic glass) were better suited to making tools than crumbly pumice or overly hard granite. The clacking of stone against stone was the sound of high technology for so long that

George's descendants had enough time to evolve into modern humans. Ice ages came and went; deserts greened into forests and dried back into deserts; entire animal and plant species emerged and disappeared; but the stone tools themselves didn't change all that much. During all of this time, there were, of course, other Paleolithic Edisons. Hominid stone workers at various times and places came up with variations on the original theme. But that theme hardly changed in 2.5 million years: start with a suitable stone blank and remove bits and pieces until you end up with a scraper, a hammer, an ax, a blade, or some other tool For some 124,000 Paleolithic generations, innovations in the use of materials were more or less footnotes to George's happy accident. During this epoch, the effect of materials engineering on the look of the landscape remained minuscule. Wherever they went and lived, the toolmakers littered the landscape with their stone hammers, scrapers, choppers, hand axes, piles of ﬂint debris, and the bony remains of their meals. Like materials engineering, litter is a Paleolithic invention. But this litter was small scale. Even today's best spy satellites, the ones that can read a license plate from orbit, would have stood a slim chance of detecting signs of the bipedal creatures who were slowly expanding their dominion by devising ways of engineering the stuff of their world.

Each year ABC stone generously hosts our students to visit the stoneyard and warehouse. They also give an introduction to stone, describing where on earth it comes from, examples of historical applications, and the qualities of various kinds of stone. In 2019 they introduced us to a stone product from Italy called “Lapitec” which is a solid surface made entirely of stone dust compressed into sheets. The exciting aspect of this material is that it is a solid surface which does not contain unhealthy binders or epoxies.

Pure metals come from the earth. They are mined, processed, and transformed into some of the most used materials for design. Most of these metals can be recycled and used again. Some metals can be combined with each other to make alloys resulting in substances that have properties that differ from pure metals. But the energy-intensive and sometimes dangerous processes of mining, combined with a general lack of recycling, has resulted in the depletion of the natural resources which give us metals. It is predicted that the earth may run out of metals for our consumption as early as 2030.

Stuff Matters MARK MIODOWNKIK From Chapter 1, in Stuff

reusable. In other words, they had discovered the perfect material for tools, and in particular cutting tools like axes, chisels, and razors. "I have only shown a few dislocations in this sketch to make them easy to see. Normal metals have enormous numbers of dislocations which overlap and intersect." It is an odd fact that steel was not understood by science until the twentieth century. Before that, for thousands of years, the making of steel was handed down through the generations as a craft. Even in the nineteenth century, when we had an impressive theoretical understanding of astronomy, physics, and chemistry, the making of iron and steel on which our Industrial Revolution was based was achieved empirically- through intuitive guesswork, careful observation, and a huge slice of luck. ( Could Brian have had such a slice of luck and simply stumbled upon a revolutionary new process for sharpening razor blades? I found that I wasn't prepared to dismiss the idea.) During the Stone Age, metal was extremely rare and highly prized, since the only sources of it on the planet were copper and gold, which occur naturally, if infrequently, in the Earth's crust (unlike most metals, which have to be extracted from ores). Some iron existed too, most of it having fallen from the sky in the form of meteorites.

This ability of metals to transform from a soft to a hard material must have seemed like magic to our ancient ancestors. It was magic to Brian too, as I soon found out. He explained that he had invented his machine by trial and error, with no real appreciation of the physics and chemistry at play, and yet it seemed that he had somehow succeeded. What he wanted from me was to measure the sharpness of the razors before and after they had been through his process. Only this evidence would allow him to begin serious business discussions with the razor companies. I explained to Brian that it would take more than a few meas urements for them to take him seriously. The reason is that metals are made from crystals. The average razor blade contains billions of them, and in each of these crystals the atoms are arranged in a very particular way, a near-perfect three-dimensional pattern. The bonds between the atoms hold them in place and also give the crystals their strength. A razor gets blunt because the many collisions with hairs that it encounters force bits of these crystals to rearrange themselves into a different shape, making and breaking bonds and creating tiny dents in the smooth razor edge. Resharpening a razor through some

Radivoke Lajic, who lives in northern Bosnia, is a man who knows all about strange bits of metal falling from the sky. Between 2007 and 2008 his house was hit by no fewer than five meteorites, which is statistically so hugely unlikely that his claim that aliens were targeting him seems almost reasonable. Since Lajic went public with his suspicions in 2008, his house has been hit by another meteorite. The scientists investigating the strikes have confirmed that the rocks hitting his house are real meteorites and are studying the magnetic fields around his house to try to explain the extremely unusual frequency of them. In the absence of copper, gold, and meteoric iron, our ancestors' tools during Stone Age were made of flint, wood, and bone. Anyone who has ever tried to make anything with these kinds of tools knows how limiting they are: if you hit a piece of wood it either splinters, cracks, or snaps. The same is true of rock or bone. Metals are fundamentally different from these other materials because they can be hammered into shape: they flow, they are malleable. Not only that, they get stronger when you hit them; you can harden a blade just by hammering it. And you can reverse the process simply by putting metal in a fire and heating it up, which will cause it to get softer. The first people to descover these properties ten thousand years ago had found a material that was almost as hard as a rock but behaved like a plastic and was almost infinitely

Above: Radivoke Lajic and the ﬁve meteorites that have hit his house since 2007. electronic mechanism, as he proposed, would have to reverse this process. In other words, it would have to move atoms around to rebuild the structure that had been detroyed. To be taken seriously, Brian would need not just evidence of such rebuilding at the sacle of the crystals but a plausible explanation at the atomic scale of the mechanism by which it

"A metal crystal, such as exists inside a razor. The rows of dots represent atoms."

worked. Heat, whether electrically produced or not, usually has a different effect than the one he was claiming: it softens metal crystals, I explained. Brain was adamant that his electronic machine wasn't heating the steel razors. It may be odd to think that metals are made of crystals, because our typical image of a crystal is of a transparent and highly faceted gemstone such as a diamond or emerald. The crystalline nature of metals is hidden from us because metal crystals are opaque, and in most cases microscopically small. Viewed through an electron microscope, the crystals in a piece of metal look like crazy paving, and inside those crystals are squiggly lines these are dislocations. They are defects in the metal crystals, and represent deviations in the otherwise perfect crystalline arrangement of the atoms - they are atomic disruptions that shouldn't be there. They sound bad, but they turn out to be very useful. Dislocations are what make metals so special as materials for tools, cutting edges, and ultimately the razor blade, because they allow the metal crystals to change shape. You don't need to use a hammer to experience the power of dislocations. When you bend a paper clip, it is in fact the metal crystals that are bending. If they didn't bend, the paper clip would be brittle and snap like a stick. This plastic behavior is achieved by the dislocations moving within the crystal. As they move they transfer small bits of the material from one side of the crystal to the other. They do this at the speed of sound. As you bend a paper clip, you are causing approximately 100,000,000,000,000 dislocations to move at a speed of hundreds of meters per second. Although each one only moves a tiny piece of the crystal (one atomic plane in fact), there are enough of them to allow the crystals to behave like a super-strong plastic rather than a brittle rock.

Clay is made from naturally occurring substances found in the top layer of the earth's crust. There are several kinds of clay, a variety of colors and textures, each with its own intrinsic properties. When clay is heated to very high temperatures, clay is transformed into ceramic - in fact, the word “ceramic” comes from ancient Greek meaning “burnt earth”. Clay and ceramics have been used by humans for millennia and in recent decades, with the addition of technology has become a high performance material used in many technical applications.

Clay—Ceramics

When clay is heated two things happen:

Clay is “a stiff, sticky ﬁne-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil.” The word ceramic comes from an ancient Greek word for “burned earth”.

1. Water evaporates, leaving a crystal structure. 2. Higher temperatures cause atoms to jump back and forth, and some never go back to their original spots, creating billions of bridges of atoms. Essentially tightening the structure and creating a more dense mass. Different clays have different mineral content, which dictate the strength and density of the ceramics when ﬁred. "Clay Transformation", in Stuff Matters.

Layers Studio, Ceramic Trays, 2016. High craft rather than high tech. Making use of ceramics’ inherent property: electrical conductivity and semiconducting ceramics.

Studio Furthermore, Tektites, 2016.

Ceramics, on the other hand, are impervious to UV degradation or chemical attack. They resist scratching better than any other material, too. Oils, fats, and most stains just bounce off them. Tannins and a few other molecules do stick to them, but acid or bleach cleans them fairly easily. As a result, ceramics keep their looks for a very long time. In fact, if it wasn't for the crack in my cup, which runs from its lip to its handle and has become stained with tannins, it would look pretty much the same as it did fifty years ago. There are very few things you can say that for. Paper cups may seem sustainable because paper is recyclable, but the wax coating required to make them waterproof makes this almost impossible. For real sustainability, we must look to ceramics. Practicalities, aside, there is a social stigma attached to serving tea in paper, plastic, metal, or pretty much any material other than ceramic. Tea drinking is about so much more than ingesting fluid: it is a social ritual and a celebration of certain ideals. Ceramic cups are essential part of this ritual - an essential part, therefore, of a civilized home. The story of how ceramics got their high status dates from a long time ago, before paper, before plastics, before glass, and therefore metal. It all began when humans started putting the clay from river beds into fires in the realization that they could transform it. It didn't just dry out. No, something else took place that turned the soft squidgy clay into a rigid new material that had almost all the qualities of stone. It was hard and strong and could be shaped into storage and collecting vessels for grain and water. Without these vessels, agriculture and settlements would have been impossible, and civilization as we know it would never have got off the ground. Roughly ten thousand years later, these vessels came to be known as pots and this simple species of ceramic as pottery. But these early ceramics were not really like stone. They were fragile, easily broken, dusty, and porous (because at a microscale their skin was full of holes). Terra cotta and earthenware are modern relatives of these early ceramics. They are beautifully simple to make but are still terribly weak. There have been countless occasions when I have put one of these terra cotta dishes, usually bought on holiday, into the oven containing some casserole only for it to emerge an hour later cracked and leaking. Of all places, the oven is where ceramics should be comfortable, because that's where they were formed, but terra cotta fails time and time again. The reason is that liquid seeps into its pores and then expands into steam when heated, turning the pore into an exploding microcrack that eventually links up with other micro-cracks like tributaries of a river, and finally erupts on the surface of the terra cotta dish, spelling an end not just to the dish but, as often as not, to the meal within it, too.

Unlike metals, plastics, or glass, ceramics cannot be melted and poured. Or rather, we don't have the materials that can withstand the temperatures required to contain such liquids. Ceramics are made from the same stuff as mountains, rocks, and stone, whose liquid form is the lava and magma of the Earth. But even if lava could be captured and poured into a mold, it would not form a strong ceramic- certainly not one that you would recognize or make a cup from. What forms is, of course, volcanic rock, which is full of holes and imperfections. It takes millions of years of heat and pressure deep inside the Earth to tun such stuff into the so called igneous rocks adn stones that make up mountains. For these reasons, attempts to make artificial substitutes for rock either use chemical reactions, which is how cement and concrete work, or, in the case of pottery, involve heating up clay in a furnace, not to melt it, but instead to take advantage of a very unusual property of crystals. Clay is a mixture of finely powdered minerals and water. Like sand, these mineral powders are the result of the eroding action of the wind and water on rocks, and are in fact tiny crystals. Clays are formed often in river beds, How firing of ceramics transforms an assembly of small crystals into a physically coherent single material

[...] Some plastic cups joined the household when my brothers and r were born. Like most objects designed for children, they are colorful and robust, and this suits the drinks they contain, which tend to be much sweeter and fruitier than tea. The feeling of soft plastic in the mouth, meanwhile, is warm, comforting, and safe. They look jolly and sweet, the material mirroring the state of infancy. It would be appropriate if plastic juice cups grew up to be ceramic tea cups as they got older, becoming stronger, stiffer, and more distinguished. But sadly what happens to plastic cups is that they die young, structurally degraded by the UV rays of the sun. Every picnic takes years off a plastic cup's life. Eventually they go yellow and brittle, and ﬁnally fall apart.

where these eroded minerals are washed down from mountains, settle on the river bed, and form a squidgy, soft dough. Different mixtures of minerals result in different kinds of clay. In the case of terra cotta, the crystals are usually a mixture of quartz, alumina, and rust, which gives the terra cotta its red color. When this is heated up, the ﬁrst thing that happens is that the water evaporates, leaving the tiny crystals aggregated in a kind of sand castle with lots of holes where the water used to be. But at high temperatures something special happens: atoms from one crystal will jump on to another nearby crystal and then back again. The atoms in some crystals, however, do not return to their original position, and gradually bridges of atoms are built between the crystals. Eventually, billions of such bridges are built, and the collection of crystals has become something more like a single continuous mass. The reason the atoms do

Stuff Matters MARK MIODOWNKIK From Chapter 9, "Refined" this is the same reason why any two chemicals react: within each crystal, all of the atom's electrons are part of a chemical bond with neighbors - they are, as it were, "occupied" - but at the edges and surfaces of the crystal, there are "unoccupied" electrons, ones that have no other atoms to bind to, the equivalent of loose ends. For this reason, all of the atoms in a crystal seek a position within the body of the crystal rather than at its surface; or, put another way, those atoms at the surface of the crystal are unstable, available and liable to relocate if an appropriate opportunity to do so comes their way. Usually, when the crystals are cold, these atoms don't have enough energy to move around and do something about their predicament. But when the tempretature is high enough, the atoms can move around: they set about reorganizing themselves so that as few of them as possible are forced to inhabit a position at the surface of the crystal - so that, in fact, there is less surface overall. In doing so, they reshape the crystals to fit together as fully and economically as possible, eliminating the holes between them. Slowly but surely the collection of tiny crystals become a single material. It's not magic, but it's magical! That's the theory, of course, but chemistry of some clays makes this easier to do than that of others. The advantage of terra cotta clays is that they are easy to find, and this reshaping process will happen at relatively low temperatures - the temperature of a fire or simple wood furnance will do. This means that making terra cotta requires only a small degree of technical know-how. As a result, whole towns and cities are built from the stuff: the common house brick is essentially a form of terra cotta. The big problem with terra cotta creramics, though, is that they never get rid of all the holes, and so never become fully dense. This is fine for house bricks, which only need to be fairly strong, and once cemented in place will not be bashed around or heated and cooled repeatedly. But it is a disaster for a cup or a bowl, which will have a thin body but be expected to withstand the rigors of the kitchen. They just don't last: one small knock and the cracks start to grow from the pores and never stop. It was the potters of the East who solved the problem of fragility and porosity. Their first step was to realize that if earthware was covered with a particular kind of ash, this ash would transform during firing into a glass coating that would stick to the outside of the earthware. And by varying the composition and distribution of the glaze, the pots could be colored and decorated. This not only stopped water getting in but it suddenly opened up a whole new aesthetic realm for ceramics. These days you quite often see this glazed earthware. There is certainly a lot of it in my kitchen - in the form of the tiles that cover the walls around the sink and cooking surfaces, making them easy to clean and pretty to look at - and it is all over bathrooms and toilets. The use of patterned tiles to cover floors, walls, and even whole buildings is associated particularly with Middle Eastern and Arabic architecture. [...]

Transparency in materials is rare and highly valued. Glass is one of the oldest materials that offers both light transmission and protection from the elements. It is inert in terms of its impact upon human health although the process of making glass is energy-intensive. Glass has become an essential material for buildings and designed objects - so much so that there is a growing concern that the sand used to make glass may become a less abundant resource.

This show unveils a first of its kind optically transparent glass printing process called G3DP. G3DP is an additive manufacturing platform designed to print optically transparent glass. The tunability enabled by geometrical and optical variation driven by form, transparency and color variation can drive; limit or control light transmission, reflection and refraction, and therefore carries significant implications for all things glass. The platform is based on a dual heated chamber concept. The upper chamber acts as a Kiln Cartridge while the lower chamber serves to anneal the structures. The Kiln Cartridge operates at approximately 1900°F and can contain sufficient material to build a single architectural component. The molten

Sims Municipal Recycling (SMR) is the processor of 100% of the metal, glass and plastic and 50% of the paper collected by the NYC Department of Sanitation throughout the ﬁve boroughs. NYC operates the largest curbside recycling program in the United States.Recycling rates nationwide have more than doubled in the last 15 years to 34.5%, due to the efforts of companies like Sims, increased global demand for commodities, and ever growing public awareness of environmental issues. In Europe, where Sims Metal Management operates numerous recycling facilities, recycling programs are even more ambitious than in the United States, and the recovery rate is closer to 60%.

SMR Recycled Glass Aggregate (RGA) is produced from residential recycled glass. RGA is used as structural and non-structural fill, drainage and filtration medium, embankment material, and pipe bedding. SMR RGA has received a Beneficial Use Determination from the New York State Department of Environmental Conservation, and has been approved in New Jersey and Pennsylvania for a wide variety of applications. RGA is cost effective – typically a fraction of the cost of competing fill materials. It is a 100% recycled product, and may provide builders and developers with Green Building LEED points, as a recycled and locally-sourced product.

Cementitious materials, especially cement and concrete, are some of the most commonly used materials in the building industry and have been used since ancient times. Early cement was made from volcanic ash and mixed with aggregate and limestone to become concrete. However, cement and concrete use immense amounts of energy in their production and now account for xx% of carbon emissions worldwide. Their signiﬁcant contribution to climate change makes us take pause before using these materials for design.

cementitious | research What is the future for concrete? Kelley Perumbeti, MFA ID '19

How can materials from nature be used as longer-lasting alternatives to cement? Portland cement requires a huge amount of energy to manufacture. Identifying materials in nature that can be used as sustainable and longer-lasting alternatives to Portland cement is an important goal for material science. These biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures, from the molecular to the macro level.

How would a biological building function? Bacteria that "heals" concrete can extend the life of the material and minimize concrete usage.

How can we reduce the amount of concrete poured and produced?

Organic Concrete (MIT) + Bottom up approach for designing cement paste + Analysis of cement paste (concrete’s binding ingredient) compared with the structure and properties of natural materials such as bones, shells, and deep-sea sponges + These biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures, from the molecular to the macro level + Goal: Identify materials in nature that can be used as sustainable and longer-lasting alternatives to Portland cement, which requires a huge amount of energy to manufacture

Bio Concrete (Self-Healing) + Bacteria used to allow concrete to self-heal + Concrete is extremely alkaline; “healing” bacteria waits dormant for years before being activated by water + Bacteria survives by being fed with calcium lactate-ﬁlled capsules made from biodegradable plastic + When water enters the concrete, the biodegradable plastic dissolves + Beneﬁt: biological buildings!

Regular concrete must be poured in thick layers to prevent cracking under pressure; bendable concrete can be applied in the form of relatively thin, light paving slabs.

Fire-Resistant Concrete (SelfCompacting and Vibrated) + Concrete typically cracks/flakes under fire this provides a new solution + Polypropylene (PP) fiber added to concrete + When exposed to high temperatures, these fibers melt away and leave a network of canals for the water vapor to escape, preventing pressure from building inside + Benefits: safer, more efficient, and cheaper for construction + Concerns: use of polymers!

Bendable Concrete (ConFlexPave) + Contains polymer microﬁbers that are thinner than the width of a human hair & distribute loads evenly across the entire slab instead of one location + Supposed to be tough as metal and at least twice as strong as conventional concrete under bending + Been tested in the lab, using tablet-sized pieces. Plans to install full-size slabs in locations around the university campus to see how they stand up to pedestrian and vehicular traffic + Goal: help to reduce the amount of concrete poured and produced

FACULTY PRESENTATION Material Health Impacts PORTLAND CEMENT The production of portland cement is energy intensive and emits carbon dioxide, one of the greenhouse gases that can cause global warming by trapping the Sun’s radiant energy in our atmosphere. Cement production can emit other hazardous substances such as mercury, arsenic and chromiumwhich can cause damage to human kidneys and nervous systems - especially children.*

Portland Cement FLY ASH Fly ash is a biproduct of coal ﬁred power plants and is made up of elements which can be harmful to human health. These include silicon dioxide, aluminum oxide, calcium oxide (plus trace amounts of arsenic, beryllium, boron, cadmium, chromium, hexavalent chromium, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium).

Harmful to Human Health

It has been called a recycled material and used as a replacement for the energy intensive portland cement, but the health risks are concerning. The health effects can be: eye, skin, respiratory irritation; chemical burns; silicosis; cancers; lung disease; autoimmune diseases; kidney

disease.

GLASS POZZOLON When recycled glass is ground into a ﬁne powder it can be used as a pozzolan alternative to portland cement or ﬂy ash. It is much healthier for people and for the environment. This is an encouraging use of a recycled product! New Yorkers recycle more than 180.000 tons of glass, metal and plastic per year and only 20% is currently used nglass). (80% is orphanglass).

Recycled glass is an alternative!

“How long will the concrete take to dry, do you think?” a man with a dog asked me, while we were both peering through the viewing window of the hoardings. “I dunno,” I lied. My lie was intended to cut the conversation short, which it did. It was a habitual lie, born of living in London and finding ways of politely avoiding talking to strangers. Especially as I didn’t know how he, or his dog, would take to my beginning our acquaintance by correcting him: concrete doesn’t dry out. Quite the opposite, water is an ingredient of concrete. When concrete sets, it is reacting with the water, initiating a chain of chemical reactions to form a complex microstructure deep within the material, so that this material, despite having a lot of water locked up inside it, is not just dry but waterproof. The setting of concrete is, at its heart, an ingenious piece of chemistry, which has powdered rock as its active ingredient. Not every type of rock will work. If you want to make your own concrete you need some calcium carbonate, which is the main constituent of limestone, a rock formed from the compressed layers of living organisms over millions of years and then fused together by the heat and pressure of the movement of the Earth’s crust. You also need some rock containing silicate—silicate being a compound containing silicon and oxygen, and constituting roughly 90 percent of the Earth’s crust—for which some form of clay will do. Grinding these ingredients up and mixing them together with water won’t get you anywhere, unless you want to create a sludgy mud. In order to create within them the essential ingredient that will react with the water, you need to free them from their current chemical bonds. This is not easy. These bonds are extremely stable, which is why rocks do not easily dissolve or react with many things—on the contrary, they last for millions of years. The trick is to heat them to a temperature of about 1450°C. This is a temperature far exceeding that of an average wood or coal fire, which is between 600 and 800°C if it is glowing red or yellow hot. At 1450°C a fire will glow white hot, with no tinge of red or even yellow in the flames but instead a hint of blue. It is so bright it is unnerving and almost painful to look at. At these temperatures, rock starts to fall apart and re-form to create a family of compounds called calcium silicates. It’s a family because there are lots of minor impurities that can change the outcome of what you get. To make concrete, aluminum- and iron-rich rocks are the magic ingredients, but only in the correct proportions. Once it has all cooled down, the result is a powder the gray-white color of the moon. If you put your hands through it you find that it has the silky texture of ash—there is something atavistic about it—but your hands soon feel dried out as if under a subtle type of attack. This is a very special material with a very dull name: cement. If you now add water to this powder it sucks it up with ease and darkens. But instead of forming a slushy mud, which is what happens if you add water to most powdered rock, a series of chemical reactions takes place to form a gel. Gels are semisolid and wobbly types of matter—the jelly served at children’s parties is a gel, and so too is a lot of toothpaste. It doesn’t slosh around like a liquid because it has an internal skeleton that prevents the liquid moving. In the case of jelly this is created by the gelatin. In the case of cement, the skeleton is made up of calcium silicate hydrate fibrils, which are crystal-like entities that grow from the calcium and silicate molecules, now dissolved in the water, in a way that appears almost organic (see the picture below).

Barbican center, Chamberlin, Powell and Bon, London 1982.

So the gel that forms inside cement is constantly changing as the solid internal skeleton grows and further chemical reactions take place. As the fibrils grow and meet, they mesh together, forming bonds and locking in more and more of the water, until the whole mass transforms from a gel to a solid rock. These fibrils will bond not only to each other but also to other rocks and stones, and this is how cement turns into concrete. Cement is used to bond together bricks to make houses and stones to make monuments, but in both these cases it is wedged between the cracks as the minority component, an urban glue. When it is made into concrete by mixing it with small stones, which play the role of tiny brocks, it fulfils its potential to become a structural material.

Stuff Matters MARK MIODOWNKIK From Chapter 3, "Fundamental"

As with any chemical reaction, if you get the ratio of the ingredients wrong, then you get a mess. In the case of concrete, if you add too much water there won't be enough calcium silicate from the cement powder to react with, and so water will be left over within the structure, which makes it weak. Similarly, if you add too little water there will be unreacted cement left over, which again weakens the structure. It is usually human error of this sort that proves the undoing of concrete. Such poor concrete can go undiscovered but then lead to catastrophe many years after the builders have departed. The extent of the devastation due to the 2010 earthquake in Haiti was blamed on shoddy construction and poor-quality concrete: an estimated 250,000 buildings collapsed, killing more than 300,000 people, and making a million more homeless. What is worse is that Haiti is by no means unusual. Such concrete time bombs are scattered throughout the world.

The first architectural walls were woven, states art historian Indra Kagis McEwen. With two upright sticks and fiber spanning between, early builders made walls on a vertical loom. Whether heavy tapestry, or light, transparent textile, flexible materials are incredibly versatile and invaluable to design. Textiles are made of fiber, both natural and synthetic. Likewise, color dying can use either natural or synthetic sources. Textile manufacturing is one of the most water intensive industries. Much research is currently underway to change textile manufacturing processes to be more sustainable.

In use, the chemicals in plastics can leach out of the material and enter human and animal bodies causing problems in normal functioning.

When they are disposed of, plastics do not biodegrade. Instead, with exposure to UV light, they break down into small pieces and make their way into water systems. Currently, over 8 million tons of plastic end up in the ocean each year. Nonetheless, the petrochemical industry remains the fastest growing sector of manufacturing since the 1960s, and over 300 million tons of plastic continue to be created annually. We recommend avoiding the use of plastic for any design application, if possible.

How was the invention of house paint significant for society? How does the production of acrylic paint affect people and the environment? How does this paint affect people who live with it in their homes, schools, and workplaces?

What innovations are currently happening with plastic to make it more sustainable? What innovation and experimentation is happening currently? How will plastic play a role in the future? What are the types of plastics? What technologies have been explored to reduce its environmental and health impacts? Examples: Bacteria breaking down plastic, compostable plastics.

What are the environmental and sociopolitical impacts of the production of polyvinyl chloride (PVC)? Where is it produced? Who are the communities that live near PVC factories, and how have they been affected in the United States? What policies have made it possible for PVC to be continued to be produced and what is the history of those policies? What role do politics and lobbyists play?

+ Bail of plastic bags at SIMS Municipal Recycling in Brooklyn, New York.

Recycling plastics. When did particular plastics (PET, HPDE, PS) begin to be recycled? What types of plastics are challenging to recycle and why? What percentage of plastics end up in the waste stream? What is the process of recycling? What are the human and environmental impacts of recycling these kinds of plastics? How has recycling affected cultures?

If we imagine plastic at the end of its useable life, it is very hard to advocate for its use in any new designed object or space. 64

@jmkmaterials Aside from the chemicals we knowingly ingest, plastic packaging contains bisphenols and phthalates that can contaminate what we consume

@svmaterials Bold and vibrant, yet hazardous for the environment. The disposal of balloons has become one of the hardest chores for our communities; this isolated yellow dog could be mistaken by animals as food, putting their lives at risk.

@fionacdesign #preciousplastic is a great example of a community that is taking steps to transform how we dispose and recycle plastic. By shredding plastic waste and repurposing them into new objects, these waste products are given a second life #synthetic

@bynparsons When reading about how “polymers are forever” in The World Without Us by Alan Weisman, I was reminded of this famous scene in the 1967 film, The Graduate. The 1960s marked the slippery slope of polymer production; our oceans began to reflect the proliferation of this “forever” material...

@sustainability_and_materials Use of plastic bags has been a fundamental method, ever since collection and storage of trash came into practice. Everyday hundred thousand tons of material in different forms of plastic is produced and ends up in landfills and ocean, which is a non-biodegradable material.

MATERIAL IDENTITY A Haptic Exercise

Pictured: MFA ID Students on the ﬁrst day of Material & Performance Class, 2018.

On the ﬁrst day of class, we asked students to reach into a paper bag and, without looking, hold the object within. After a couple mins of touching they were asked to guess the material type that was in their hand and write it down. Then pass the bag to the student on their left, and guess the next material hidden within the bag. And again until each student had written guesses for 20 objects. Next the bags were opened and material types, as well as everyone’s guesses, were revealed. Some laughs, some inquisitive looks, and so began the semester of exploring, experimenting, and researching materials for design.
