Glassy
 
Glas is an amorphous solid - or a supercooled liquid, that's a matter of perspective.
Glass is made from SiO2 (silica sand), often Na2CO3 (soda), calcium-, magnesium- and/or aluminium-oxide are added to make it durable / easier to process.
By adding various metal(-oxides) one can make it coloured, smokey.
Obsidian is naturally formed glass.
Acrylic glass (Plexiglas) isn't real glass, but a transparent plastic (polymethyl methacrylate PMMA), but it looks like glass - and isn't as easy to smash. (edit: You ain't eejits, just means you can toast plexiglas or whatever glass not by definition 'glass')

Glass: fragile - enduring, smooth - rough, clear - obscuring, reflecting, refracting, taking on so many forms...

ok ok it's fiber optics, probably not glass per se, but when was the last time you saw a glowing camisole?

^yeah what I meant, can look/behave like glass somehow, but doesn't need to be glass




(in practical, the glassblowers from the technical dept. once let us try to blow our own flasks, was hard, but funny)
