[TheForge] a blacksmithing question and aceramic/pottery question

[Jerry Frost]

Terry: How about just doing a specific gravity on a piece. It may not give 
you a metallic analysis but it will give you a ballpark. If you actually 
need a correct analysis I'm thinking you need to talk to someone with a mass 
spectrometer and pay the price.
