Hello all,

I am near completing my first forge and have the ultimate goal of casting a singing bowl (or rather casting a plate and cold-working it into a bowl). HOWEVER I am running into trouble determining the composition of these bowls. Copper and copper alloys are a major component. Some of the more traditional methods call for gold, silver, mercury, copper, iron, tin, and lead. As I am not comfortable working with mercury or lead, mine will not include these.
