Billon is an alloy of equal parts silver and copper. Historically, this was used to mint coins, and that is also one of its uses in this game.

Two billon bars can be made at a smelter from 1 chunk of silver ore and 1 of copper ore, or 1 silver bar and 1 copper bar. One unit of tetrahedrite counts as both copper and silver ore at the same time, and will yield two bars of billon all by itself; this may be considered a bug.

Billon can be used to make furniture and 'other objects' at a Metalsmith's Forge.
