Non-ceramic glasses are not adequately discussed in introductory chemistry. Such glasses include polycarbonate, which many corrective lenses are made of, amber, enamel, gelatin, hard candy, coal, refrigerated glycerol, and metallic glasses that have been marketed in recent decades. What is usually discussed in elementary texts is siliceous glass, which is only one example of the state of matter known as glass. This article describes polymeric, metallic, and other glasses and their importance at a level appropriate for introductory chemistry. (Contains 2 notes.)
