Abstract: Abstract Over much of its history, silver production has been tied to lead metallurgy. For the early Middle Ages in particular, it is widely accepted that galena, a lead sulfide, was the dominant source of silver. Since galena can be associated with silver in the range of 0.1–0.5%, rarely more, this implies that tons of lead must have been laboriously processed to extract kilograms of silver. While all extant physical evidence from mines, slag and the metal itself point to this being true, this study has found evidence that extremely rich sil...
