[[40d:Bauxite|Once]] highly prized as the only practical source of [[magma-safe]] [[mechanism]]s to create magma-proof devices, its importance has declined with the addition of many new heat-resistant forms of stone as well as the ability to make [[metal]] mechanisms from [[iron]] and [[steel]]. Nevertheless, it is still used by some long-time players for nostalgia, and its rare, bloody appearance makes it an interesting aesthetic choice. |

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 [[ruby]] and [[sapphire]] (aluminum oxide: Al<sub>2</sub>O<sub>3</sub>), 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 [[cryolite]]. The development of this process transformed aluminum from an exceptionally rare metal to a cheap, utilitarian material. Dwarves have not yet discovered electricity, therefore they cannot make use of electrolysis to get aluminum from 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 [[cryolite]].
