v0.31:Fire-safe
| This article is about an older version of DF. |
Fire-safe materials are those that are not damaged by fire. These materials include glass, metal, and most stone. No types of wood are fire-safe, and neither are Template:L or Template:L. Template:L and Template:L are flammable stone, and therefore not fire-safe. Fire-safe materials are only required when the object is going to come into contact with extreme heat, such as a Template:L, Template:L, Template:L, Template:L or Template:L, or for the magma-powered versions of these facilities.
Flux materials, such as Template:L, which are consumed in the purification of Template:L to produce Template:L, are considered fire-safe. It is perfectly fine to use limestone as a flux material to make steel in a limestone smelter.
As far as the game is concerned, any material which is stable at temperatures below 11000 (1032°F, or about 555.6°C) is supposed to be considered fire-safe; due to a bug, however, the game only checks that the material has no ignition point, resulting in such oddities as Template:L being considered fire-safe. Furthermore, the game only considers Template:Ls, Template:Ls, Template:L, Template:Ls, and Template:Ls to be capable of being fire-safe - all other item types are rejected outright.
Template:L are a different thing entirely; while many fire-safe materials will still melt when submerged in Template:L, that is not an issue for buildings that are merely powered by the magma.
