@sco7sbhoy Jut curious-Have you got an analysis of the metal at all? It does look a good casting and they're usually hard to get with a pure metal.
@sco7sbhoy Some smiths seemed to know it was a good trick to add something to the Ag before casting. It doesn't always look natural, but how they found out is what fascinates me.
@SteelFolk I don’t have that information to hand, but may be researchable given its importance.
