Galena can also be used in alloy reactions requiring silver-bearing ore. Because these reactions treat the galena nugget as the equivalent of 4 silver bars, the resulting alloy will show a roughly 30% increase in value over smelting the galena separately. Galena is also magma-safe, but just barely. Since galena is a mid-value ore, however, you ...
