40d:Economic stone
Revision as of 16:33, 6 November 2009 by Erdtirdmans (talk | contribs)
Economic stones have special uses as ore, fuel or flux, or other uses like making special items. You can use the z : Stone menu to restrict or un-restrict their use in items and buildings. In technical terms, an economic stone is any stone which can be used as a reagent in any form of reaction. Obsidian is the exception because it can be used to make swords. Though technically not an economic stone, Bauxite is included here for the players' sake considering its special use for Magma-safe mechanisms.
The Stone menu will also show what each stone (except Bauxite) can be used for -- very useful for figuring out what you need to mine to make that obscure metal your noble is whining about.
