Bronze CastingSimon,

The bronze I cast is 95% copper. It will stain your finger green
or black depending on your body chemistry. Copper is thought to
have theraputic (sp?..can you get spell check for e-mail?) value
to those suffering from arthritis. I believe some of the %5 is
manganese, tin and depending on the source there may be other
constituants. Call Belmont metals in NY and ask their tech folks
for an MSDS form. J.A. J.A.Henkel Co., Inc. Moldmaking Casting Finishing
