Celadonite is a mica group mineral, a phyllosilicate of potassium, iron in both oxidation states, aluminium and hydroxide with formula K(Mg,Fe 2+)(Fe 3+,Al)[Si 4 O 10](OH) 2.. It crystallizes in the monoclinic system and usually forms massive aggregates of prismatic crystallites or, more commonly, in dull clay masses.
The crystallographic restriction theorem in its basic form was based on the observation that the rotational symmetries of a crystal are usually limited to 2-fold, 3-fold, 4-fold, and 6-fold. However, quasicrystals can occur with other diffraction pattern symmetries, such as 5-fold; these were not discovered until 1982 by Dan Shechtman .
Other work suggests that while mineral surfaces, such as those of pyrite, calcite, and rutile catalyze peptide condensation, they also catalyze their hydrolysis. The authors suggest that additional chemical activation or coupling would be necessary to produce peptides at sufficient concentrations.
Illite, also called hydromica or hydromuscovite, [6] is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate. Its structure is a 2:1 sandwich of silica tetrahedron (T) – alumina octahedron (O) – silica tetrahedron (T) layers. [5]
The clay hypothesis suggests how biologically inert matter helped the evolution of early life forms: clay minerals form naturally from silicates in solution. Clay crystals, as other crystals, preserve their external formal arrangement as they grow, snap, [clarification needed] and grow further.
Kyber crystals vary in shape and color, but all are deeply connected to the Force, the vast energy field connecting all living things. They are most commonly used by the Jedi and Sith in making lightsabers; but larger, rarer crystals are sometimes used in superweapons, including the planet destroying Death Star. Lerasium Mistborn

It prevents ice crystal formation and is a very fast process: -23,000 °C/min. Currently, vitrification techniques have only been applied to brains ( neurovitrification ) by Alcor and to the upper body by the Cryonics Institute , but research is in progress by both organizations to apply vitrification to the whole body.
