Hi folks,

I'm just learning about casting, and taking a great local course, but had a metal composition question. I'll be working with sterling silver, but am considering mixing it with a little graphite. The reasoning is not metallurgical but sentimental - as the STP thermo equilibrium state of carbon, graphite is forever (even moreso than diamonds).

Does anyone have any experience with the metallurgical consequences? Will I be making the item brittle? Will they simply not mix? I'm casting a ring...

Thanks!
