Glasses and Quartz

Glasses are non-crystalline, amorphous solids that are usually transparent. They can be roughly formed via thermal methods. All material and optical properties are affected by a variety of alloying materials so many specific types of glass have been created for specific advantages. All glasses feature low thermal conductivity with generally low thermal expansion as well.
