'''Fire-safe materials''' are those that are not damaged by [[fire]]. These materials include [[glass]], most [[metal]] (everything ''but'' [[bismuth]], [[lead]], [[tin]], [[zinc]], and all three pewters) and most [[stone]]. [[Nether-cap]] is the only [[wood]] that can withstand fire (and even [[magma]]) thanks to its fixed temperature, but the game does not recognize it as a fire-safe building material. More esoteric fire-safe materials include [[ash]], [[potash]], [[pearlash]], and [[dragon]] tallow [[soap]] "bars". Counterintuitively, [[Bituminous coal]], [[lignite]], [[charcoal]], and [[coke]] '''are''' considered fire-safe, since they only catch fire when they're hot enough (see below).

[[Fire-safe]] materials are those that are not damaged by [[fire]]. These materials include glass, (most) metal (tin has a low enough melting point to turn into a pool of tin if exposed to fire), ash and most stone. No types of wood are fire-safe, and neither are [[charcoal]] or [[coke]]. [[Bituminous coal]] and [[lignite]] are flammable stone, and ought not be fire-safe, but the bug mentioned below allows them to be safely used as a fire-safe building material. Furthermore, the game only considers [[bar]]s, [[block]]s, [[stone]], [[log]]s, and [[anvil]]s to be capable of being fire-safe - all other item types are rejected outright.

For the purpose of job item requirements (e.g. in custom [[reaction]]s or when constructing certain buildings), only [[bar]]s, [[block]]s, [[stone]], [[log]]s, and [[anvil]]s can be classified as "fire-safe materials" - all other item types are rejected outright. Fire-safe materials are only required when the object is going to come into contact with extreme heat, such as all conventional [[furnace]]s and the [[metalsmith's forge|forge]]. For the magma-powered versions of these buildings, as well as anything that will be in direct contact with magma (such as [[floodgate]]s), fire-safe is not enough: it has to be [[magma-safe]].

As far as the game is concerned, only materials which are stable at the [[temperature]] {{ct|11000}} (i.e. MELTING_POINT/BOILING_POINT/IGNITE_POINT/HEATDAM_POINT greater than 11000 and COLDDAM_POINT less than 11000) are considered fire-safe. Despite this temperature being considered fire-safe, actual [[fire]] can generate temperatures significantly higher - in particular, all burning items generate temperatures up to 200 degrees ''above'' their material's ignite point, so once a "fire-safe" item manages to get ignited (e.g. by exposure to [[magma]]), it can easily spread further. For practical purposes, anything which has an IGNITE_POINT should be treated as not fire-safe.
