Glass

For worthless pieces of colored glass, see Gem.

Glass is a material that appears in NetHack. Most glass items are fragile and break when thrown or subjected to certain kinds of blunt force. However, glass artifacts and gems are not fragile.

"Crystal" objects in NetHack, excluding the dilithium crystal, are actually made of glass.
