Fire-safe materials are those that are not damaged by fire. These materials include glass, most metal (bismuth, lead, tin, zinc, and all three pewters melt), 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 fire-safe building material. More esoteric fire-safe materials include ash, potash, pearlash, and dragon tallow soap "bars". Bituminous coal, lignite, charcoal, and coke are all flammable and ought not be fire-safe, but the bug mentioned below allows them to be used as fire-safe building materials. Furthermore, the game only considers bars, blocks, stone, logs, and anvils to be capable of being fire-safe - 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 furnaces and the forge. For the magma-powered versions of these buildings, as well as anything that will be in direct contact with magma (such as floodgates), fire-safe material is not enough: it has to be magma-safe.
As far as the game is concerned, only materials which are stable at the temperature 11000 °U (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, any burning item will heat up to 200 degrees above its material's ignite point).Bug:5011 For practical purposes, anything which has an IGNITE_POINT should be treated as not fire-safe, so as to avoid triggering this bug.
