CRYSTALLIZATION IS ALSO A CHEMICAL SOLID–LIQUID SEPARATION TECHNIQUE, IN WHICH MASS TRANSFER OF A SOLUTE FROM THE LIQUID SOLUTION TO A PURE SOLID CRYSTALLINE PHASE OCCURS.

WHAT IS CRYSTALLIZATION?

Crystallization is the (natural or artificial) process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. There are many examples of natural process that involve CRYSTALLIZATION. Geological Time Scale Process Samples include: natural (mineral) crystal formation (see also gemstone); stalactite/stalagmite, rings formation. human time scale process examples include: snow flakes formation; honey crystallization (nearly all types of honey crystallize). HOW? heating solution till supersaturation cooling of mixture molecules of solute connect forming a unique molecular matrix FACTORS size - rate of cooling & initial temperature shape - molecular structure of solute & available space

CRYSTAL LATTICES There are seven systems of crystal structures, which are also called lattices or space lattices: Cubic or Isometric - This shape includes octahedrons and dodecahedrons as well as cubes. Tetragonal - These crystals form prisms and double pyramids. The structure is like a cubic crystal, except one axis is longer than the other. Orthorhombic - These are rhombic prisms and dipyramids that resemble tetragons but without square cross-sections. Hexagonal - Six-sided prisms with a hexagon cross section. Trigonal - These crystals have a 3-fold axis. Triclinic - Triclinic crystals tend not to be symmetrical. Monoclinic - These crystals resemble skewed tetragonal shapes.

WHY CRYSTALLIZATION? Separating inside and outside through a form. This separation process happends through a form of modular unique crystals that are specifically dependent in addition to the physical triggers of the surroundings like wind, temperature and rain.

BECAUSE A SNOWFLAKE NEVER GROWS TO FORM A SPATIAL STRUCTURE, THIS OBJECT IS A HYBRID OF BIO-INSPIRED SHAPES AND A GEOMETRICAL CATEGORY, EMBRACING A METAPHORIC LAYER OF INFINITY.

FORM GENERATION


FORMATION OF SNOWFLAKES In the Earth atmosphere, when the temperature is below freezing point, water vapor coats tiny particles or dust into ice crystals. The floating molecules of water that form each ice crystal arrange themselves into triangular or hexagonal surfaces. Overtime these crystals becomes increasingly weighty until they lose to gravity and fall to earth. All snowflakes are formed in the same way, yet each snowflake is unique. Because a snowflake never grows to form a spatial structure, this object is a hybrid of bio-inspired shapes and a geometrical category, embracing a metaphoric layer of infinity.

Snowflakes all follow slightly different paths from the sky to the ground —and thus encounter slightly different atmospheric conditions along the way. Therefore, they all tend to look unique, resembling everything from prisms and needles to the familiar lacy pattern. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets of the snowflakes. Finally, the molecules of water that form each tiny ice crystal naturally arrange themselves into a hexagonal (six-sided) structure. The result will be a snowflake with six sides or six arms.

CONCEPT My aim is to cling crystal growth to the structure, so that the crystal changes the appearance of the building through the use of solids (dust) and then cavities that creates bridges that forms a complex structure.

FORM EVOLUTION


FORM GENERATION A COMPLEX STRUCTURE BREAKING OUT FROM A SIMPLER ONE. Started as a dust, and then through cavities and bridges created the form starts forming. Just as the formation of a snowflake where it forms through the combinations of needle, column, plate, and rime. The floating molecules of water that form each ice crystal arrange themselves into triangular or hexagonal surfaces. Overtime these crystals becomes increasingly weighty until they lose to gravity and fall to earth. Therefore the form depended on the triangular modules that forms the whole structure which different patterns that represents how each molecule forms through the solids and voids within each module. Furthermore as the molecules starts reaching earth’s surface the pattern starts getting more complex which more cavities and bridging that was inspired from the form generation of a snowflake.
