Introduction Crystals widely exist in the nature. This report describes the formation and development of natural crystals, crystals form analysis, as well description of the aesthetic characteristics of the crystal. This project will clarify the various attempts to tap the potential of the crystal as a building material in modern architecture. Comparing of different crystals, cheap and environmentally friendly salt is chosen as the main material. The combination of different support materials with salt , developing new effects used in the performance, such as the sense of space, changing the material properties, texture and so on. Plastic is picked as it can highlight the salt crystal. Device, structure and morphology are specially designed in order to control the effect of crystallization. A specific salt area is chosen for project design and the project try to reflect the area or even the cityâ&#x20AC;&#x2122;s personality, regional and historical context. How the crystals glow as an element of the structures, giving it a new vitality in the architectural design, making the buildings more diversified, more personalized, and more humane.

Brief Crystallization, acts as a growth resistance, and can be seen in nature with significant aesthetic effects. As a potential use of this feature, crystallization can be used as an active growth element of the building. Our aim is to cling crystal growth to the structure so the crystal changes the appearance of the building throughout the buildings life cycle. The forces of nature, such as wind and other conditions continuously modify the topology of the building, allowing users access to different spatial experiences.

CONCEPT - Crystallization - Mesh growth system

CONCEPT Mesh growth system is seen in many places in nature. Like thousands of biological growth systems in nature, this shape, in fact, is the development of a shape under the fractal law, restructuring can be extended infinitely. This structure has the ability to span large spaces, save material and can withstand a lot of force.

Bacteria curtain bell shaped, a significant dictyophora indusiata grid, with polygon mesh. Light, vaulted complete.

leaf vein Regular distribution in leaves ,support leaf to extend in space. There are specific arrangements and classifications.

spider web Build nests, capturing prey, directional catchment, with a variety of forms

salt crystal Most occur in a particular environment, such as the lake or the sea with high salinity , forming a unique scene.

snow cream The most common crystals in daily life, easily affected by temperature.

Crystallization by certain conditions and procedure, the crystal having a predetermined shape from a non-solid material, and to obtain its unique wonderful shape, color, surface.

Why combine them together

Crystallization 1. The crystal climbs along the system it is attached to to form a unique morphology and surface 2. As time increases, the crystal thickens and hardens 3. Crystal climbs along to fill the gap grid, forming a dense surface 4. So a thin, linear geometry transforms to thick three-dimensional mesh system

Mesh Growing System 1. Flexible modeling 2. Maintain a certain growth law, there is the possibility of extending the growing 3. Structural stability across a large span, can withstand a lot of force 4.The web can capture falling objects. 5.Can form a complex three-dimensional system

CONCEPT

Spider web system Spider web, one of the most common network system in nature, which is woven by the spider silk to nest and catch prey, Features: lightweight, able to cross a larger span, can withstand a certain force, can cling to something attached to the web, with the possibillity of extension and growth, the possibillity of forming a complex three-dimensional structures.

CONCEPT

As cobwebs are able to cling to dew and catch food, so we think that this priniple can be applied to the crystal support structure. Like the spider webs use of density to control the probability of catching prey, we think that with a sufficiently dense network, there will be a possibility for larger crystals. This lightweight mesh structure can withstand a certain force.

Material Test

In order to study the characteristics of the various crystalline, crystalline regularity, crystallization conditions, we selected in daily life, the production of the more common variety of crystals, such as salt, soda, baking soda, magnesium sulfate, copper sulfate. In the initial test material, we selected different kinds of pure crystalline salts which were dissolved in water. We put a thin line into the solution to observe the growth and adhesion of the crystallization solution after natural cooling.

Process of making a saturated brine

Step one

Sodium chloride was selected as a base material, and then combined with different materials suchas cardboard an sponge for the crystallization experiments. Different effects of the crystallizationof sodium chloride in different materials were explored, including the crystallization rate, the size of the crystal, the pattern of crystal, and the effect on the material after crystallization. In fact, usingdifferent materials combined with sodium chloride not only affects the crystallization but also changes the nature of the material itself.

Comparison: When combined with salts and organic materials (such as wood, card, cloth, etc.), both salt and materials combine with each other well. Not only they crystalline on the material surface, but also crystalline in the material inside. Therefore, it has also an impact on the internal structure of the material,furthermore, it evaporates more slowly due to the absorbent quality of the material,. When combined with salt and inorganic materials (such as plastic), salt crystals appear only in the external, salt crystals can perform vein and texture better. At the same time, it is easier to dry, the evaporation will be beneficial. And when required to re-crystallization of dissolved salts, the inorganic material does not affect itself. Easy to separate the two materials then reuse them. By comparison, inorganic materials (plastics) is more conducive to reflect the characteristics of the salt, and can be reused and will not damage the material itself, so the plastic was chosen as the main structural material in the project.

The effects by different flow directions of the crystal formation By controlling the flow direction of oversaturated sodium chloride solution thatwas lowing through the material, the effects of different flow direction generated crystals wereexplored. Saturated sodium chloride solution flowdirection was divided into three types, asfollows: a) Vertical direction - from the bottom up Objects to be placed in oversaturated sodium chloride solution, so that the object absorbs the solution according to siphon principle. Features: The part of the crystal exposed to the air had a cube shape with the crystal gradually increasing in size from bottom to top. But there is a limit in the absorption capacity, avoiding significant crystallization formation.The immersed part in the solution was hardly crystallized. b) Vertical - from the top down Suspending the object in a device, with the oversaturated sodium chloride solution poured from the top. Features: Evenly crystal, covering the complete object, crystallization patterns can exhibit major solution flow direction. c) Horizontal This is achieved by placing the object horizontally in oversaturated sodium chloride solution. The object had a large contact area with solution. Features: Objects uniformly crystallized, but only crystallization on the surface exposed to air. Comparison: By comparison, the water poured down from top to the bottom (vertical) can get better crystallization effects and artistic expression, so this method was chosen as the project major crystallization techniques.

WEB AND CRYSTALLIZATION

WEB GENERATION By adjusting different parameters, we tried to obtain different density and morphology of the web, thereby controlling the generation of the crystal at the surface. And by setting the key points to guide the crystallization in different regions of the surface to form the focus of aggregation effect. EVENLY CENTRIPETAL CENTRIFUGAL ECCENTRICALLY

Web growing system - how to help thecrystal shaping better Spider web is one of the most commonnetwork systems in the nature, woven by spider silk to make nests and catch prey. As the spider webs are able to cling to dew and catch food, this system is capable of carrying the weight and the pressure and maintains equilibrium. This principle also can be applied to the crystal support structure and maintain a certain shape and styling. Like the spider webs use the density to control the probability of catching prey, there will be a possibility to form a crystal with a certain weight on the premise of a sufficiently dense network. In the crystallization process, the crystal is attached to the web structure. By performingexperiments, it has been found that by controlling the gap and the size of the grid, it can help shaping crystals and increase the thickness of the crystal.

Most crystal structure is highly ionically bonded. Crystal adheres to the surface of the object. The crystal seed helps to form crystal. So, after the first step, when the crystal seed occurs, the crystal speed will increse.

Crystallization methods Generally, there are two types of crystallization methods, one is cooling crystallization technology, and theother is evaporation crystallization technology.The principle of the cooling crystallization is when temperature decreases , the solubility of the material is reduced, the solution has reached saturation, the excess solute that is not dissolved will be precipitated. The principle of evaporative crystallization or evaporation is the case before and after the temperature constant, the solubility constant, water reduction, i.e., a saturated solution of excess solute will precipitate. The project took a combination of the two methods. First, the use of pre- cooling crystallization by controlling temperature of the solvent, Secondly, the keeping of constant temperature, more crystals formed by evaporation crystallization.

Further research

On the basis of experiments on the web plane, we conducted further research on how crystallization happened on the three-dimensional web. According to our design, we weave two different densities of components. By immersing these two components into solution, we compare the results of crystallization after a period of time.

Experiment Description Material:Magnesium Sulphate Solvent:Water Dosage:13kg Starting temperature:100â&#x201E;&#x192; Ending temperature:28â&#x201E;&#x192;

The main steps : 1 configure supersaturated solution of magnesium sulfate. 2 Use hot water to improve the solubility, stirrring the solution to accelerate dissolution. 3. Immerse the component in the solution. When the solution temperature decreases, the crystalline precipitates in lines to generate the surface. 4. Every 2 hours remove to make the recording .

Conlusion: Dense grid is more easily crystallized than a sparse grid, also easier to form a crystal surface covering the gap. Both compoments preliminary crystallization is slow. But after a critical point, the crystallization speeds up, for a rapid formation of crytals.

FRAME ANALYSIS

Frame research -stick This is our first attempt of the frame, it is used to simulate the spiders selected point. As mentioned earlier, the spider will select a point to the same space within the weaving plane, so that the frame is used to simulate this principle with the sticks simultaing branches.

Controlling Growth Patterns

Rivers branch point

Based on the principles ofriver branch to design the shape of the the object, and thus play a role in guiding the flow of salt water.Because of the gravity and topographical conditions, the water flow will be distributed both horizontally and vertically. So we can use this principle to create and change the water flow on the object, also we can change the crystallization pattern.

Turning point Water flow

Use the objectâ&#x20AC;&#x2122;s shape and gravity to control the crystallization growth pattern

River diversion in general will help distribute the water. The idea of an alluvial fan was applied, using a normal logic that distributed water throughout the whole design, in the shape of branches that are flowing down. Water is automatically adjusted, following the principle of least resistance, when a stream of water across the bifurcation point, resistance is generated automatically creating a bifurcated flow. This form can be applied to the project design, guiding the flow of salt water.

Brick Structure By splicing sheets and components, the type of clusters can be formed of the bricks. This brick form is the most basic form which is stable and sturdy. At the same time, due to similarities between the mutually, they can stitching combination very well. Just as the very famous electronic games, Tetris, which can get a variety of combinations of multiple splicing performance results. 3D bricks, by rotating and occlusion, not only the challenge increase, but also the stability enhance. Because the interconnection of the basic shape forming a plurality of control points, it helps the water flow diversion. By forming the structure to help the flow diversion, the model can be obtained gradient effects of crystallization.

Process After the passage of time, the salt crystals gradually grow. Forming a unique texture and surface on the structure. The thickness is gradually increased while the hardness also will enhance. It helps to form and freeze the shape of the structure. The following pictures show the process of the crystal growth.

FURNITURE [Table]

Table Structure To achieve a bigger size of furniture piece, a tea table was made.Shape the cluster of components, and give some force to keep the stanning modelling. Then set up the device, run the recirculate water system,the salt will keep crystal on the structure. After salt crystallization, this tea table will become thicker and stronger. At that time, the frame will be removed, and the tea table could be stand by itself.

FINAL PROPOSAL

Discussion For function area, the previous project mainly from an aesthetic point of view to play a role in crystallization. However, in this project, in addition to aesthetics, the salt has also play a role of generating form and reinforcing structure . As the furniture piece shown in this project, the crystallization brings hardness to the structure which not only generate the form ,but also reinforce the structure. It is obvious that salt crystallization fabrication is feasible which can be used in design area, such as sofa, stools ,and resting space. By controlling the density of internal support system or by controlling the water flow, the project can control the crystal effects and create otherworldly aesthetics effects. Previous research projects are more limited. They did not combine salt crystals and natural environment together, but rather as art works or sculpture. This project chooses the specific area such as Dead Sea, Salt Lake to create some interesting design. In this way, project can get free crystalline material and keep providing a salt water. The project try to combine crystal project and natural together. The unique idea is like 'graft'. The preset structure is placed in these specific area .After crystallization, the structure will be merged into the environment and become a gorgeous landscape. The natural environmental factors just like temperature and wind also can help the crystallization. Actually, this project has limitation because it can only carry out in area with certain conditions, such as Salt Lake or the Dead Sea. Meanwhile, it reflects the area or even the city's personality.

Salt crystals Experience Center Currently the crystals in these areas are naturally formed. By designing the initial structure, forming the special space, and then place these structures in these specific environment, through some artificial means (e.g., pre-soaked, flow control) to guide the growth of crystals clinging to the preset architecturally, forming a unique ornamental landscape. Due to the existing landscape, the occurrence of crystallization is spontaneous without certain organization. The major opportunity for these formations of crystals is high tide. The water rises to the surface of the rock soaking it in brine , bringing the dissolved salt to the surface ,then strong sunshine will rapidly evaporate the moisture , salt will condense and pile up, thereby forming different shapes of crystal. It seems that these crystals have a large area , scalability, but they are mainly on the surface or covered in some rocks and it does not allow people to walk through which means it canâ&#x20AC;&#x2122;t offer full three -dimensional experience with crystal .Designing the guiding walking path and unique internal structure will provide multidimensional experience of space. The goal was to make it the infrastructure design close to the regional natural style and close to the original natural system, by collecting information on the region, seeking the best position of the insertion, to get the best results in harmony with the environment. There is a possibility to create a unique and interesting pavilion or landscape design for their site, based on people behavior, local growth logic and physical behavior. They are conceived from geometric nonlinearity. They have the structure, space and other necessary qualities. Structures will be previously treated by artificial means, and then slowly crystallization in the evaporation process occurs over a long term. The crystals keep growing, from less to more, from thin to thick; the observer can enjoy the whole process of crystal growth. Crystal growth process also changes the appearance of the structure and makes the space more interesting as some original walk path may be hindered due to the thickening of the crystals. Actually crystallization is not a unidirectional growth, but reversible. Because of the influence of wind, water and other factors, crystal can be re-dissolved or eroded. This would produce certain changes in the crystals appearance and help to form more diverse and worth watching manifestations while maintaining vitality and change, rather than being static
