ORIGINAL: InkedMaster Glass by definition is an amorphous solid material. it is amorphous because it is neither a solid or a liquid, but exists in a vitreous state hi all-- i was just reading this lately: "A glass[y material] is formed when a molten material is cooled so rapidly that its atoms are trapped in nearly the same positions as in the liquid. These supercooled liquids, by definition, possess an amorphous or glassy structure. For most liquids, the cooling rate necessary to produce a glass is so high that these substances do not occur naturally. For others, however, such as common sand (silica), a very modest cooling rate will result in the amorphous structure. Obsidian is an eample of a naturally forming silica glass." (Why Things Break, Mark E. Eberhart) Amorphous means the atoms of the material are oriented randomly. thornhappy the nerd
