Bauxite used to be the only Template:L Template:L. This made it highly valuable as the only practical source of magma-safe Template:Ls to be used in Template:Ls. However, nowadays, dwarves have a wide selection of hard to melt rocks, and can even make mechanisms from certain types of Template:L (including Template:L and Template:L), and as a result, bauxite is no longer so important.

Some older players might still prefer to use it for the sake of nostalgia, though, and its pleasing dark red color makes it look like the walls are always dripping with Template:L.

In real life, bauxite is an ore of Template:L, but the technology required to extract it is beyond the level possessed by dwarves.

Bauxite can also contain Template:L and/or Template:L.

In Real Life

Bauxite is a stone comprised primarily of the minerals gibbsite (Aluminum Hydroxide: Al(OH)₃), boehmite (Aluminum Oxide-Hydroxide: γ-AlO(OH)), and diaspore (Aluminum Oxide-Hydroxide: α-AlO(OH)) (none of which are individually present in Dwarf Fortress). Bauxite forms by the weathering and mineralization of various aluminum-rich soils or clays. Despite the correspondence in game, corundum, the mineral that makes up Template:L and Template:L (Aluminum Oxide: Al₂O₃) does not form in bauxite.

Extracting aluminum from bauxite, even in the most primitive way, requires the use of the Hall–Héroult process: the electrolysis of bauxite which has been dissolved into molten Template:L. Dwarves have not yet discovered electricity, therefore they cannot make use of electrolysis to get aluminum from bauxite. (If it were implemented, lightning might work)

Raws

an ore of aluminum, but through a too-advanced process, in-game as the source of the corundum gemstones (ruby and sapphire) bauxite melts around 2000C, so it's not practical to smelt it for aluminum (magma only goes up to 1300-1400) [INORGANIC:BAUXITE] [USE_MATERIAL_TEMPLATE:STONE_TEMPLATE] [STATE_NAME_ADJ:ALL_SOLID:bauxite][DISPLAY_COLOR:4:7:0][TILE:'+'] [ENVIRONMENT:SEDIMENTARY:CLUSTER:100] [MELTING_POINT:13600] [BOILING_POINT:15000] [IS_STONE]
