Rock crystal, one of many types of quartz crystals (SiO₂), is a type of gem. When combined with pearlash at a glass furnace, it can be used to make crystal glass items. Due to a bug, however, this is currently not functional - despite rough rock crystals being available, the game will announce 'Needs glass-making rough gems'^Bug:1498. See the bug entry for information on how to patch this bug for version 0.31.25 on Windows or Linux.
