Editing v0.31:Glass

{{quality|Fine|06:19, 8 September 2010 (UTC)}}{{buggy}}{{av}}

Glass is produced at the [[glass furnace]] using [[fuel]] with either [[sand]] (green glass), [[sand]] and [[pearlash]] (clear glass), or [[rock crystal]] and pearlash (crystal glass). A [[magma glass furnace]] can also be used, in which case no fuel is required.  Raw glass (of all three types) can now be acquired from some [[trading|trade]] caravans and be purchased in the [[embark]] screen.  Note that raw glass can '''''not''''' be made into glass items, but can only be [[gem cutting|cut]] into [[gem]]-like items which can be used for [[decoration|decorating]] items.  You have to buy or collect [[sand]] to get the raw materials to make glass.

Glass is valued based on the difficulty in making it, with green glass being the lowest value and crystal glass being the highest.

== Uses ==
Glass may be used to produce most things that can be produced at a [[carpenter's workshop]], with the exception of beds, medical supplies, training weapons, and possibly other things. In addition, it may be used to produce [[gems#Glass|glass gems]]. These, especially ones made of green glass, are excellent practice for aspiring jewelers (and their production provides experience for [[glassmaker]]s). Glass can also be shaped into [[block]]s which can be used to build [[workshop]]s and [[construction]]s. You can even make glass trap components.

For more information on the use of glass, see the [[Glass industry]] page.

Raw and cut glass storage options can be found under the Gem [[stockpile]] sub-menu. Glass blocks are stored in Bar/Block stockpiles.

== Bugs ==
*Making raw crystal glass or crystal glass items 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.
*Raw clear glass and raw crystal glass cannot be selected for cutting or encrusting tasks at the jeweller's workshop. The tasks are available in the Job Manager screen.
*Using the Job Manager screen to cut crystal glass will satisfy a noble's demand for 'crystal glass items.'

==Glass and Magma==
Glass behaves somewhat oddly with [[magma]], despite being strictly magma-safe (with a melting point of 13,600°U) - glass objects dropped into magma tend to disappear instantly (a property seemingly shared by every non-INORGANIC material), but '''built''' glass furniture will survive indefinitely when covered with magma.

==Physical Properties==
Through memory hacking, the material properties of each type of glass have been determined; for reference, they have been reconstructed below as material definitions:
