I'm from Montreal, Canada. One of my art patrons lives in Henderson, NV. I'm going to visit him in April. He's a carver/sculptor himself and knows a lot about mold making. Part of the reason I'm going to see him is to see about making molds to do some poured silver (maybe gold?) Mandalas. All you gold & silver folks on here have given me some cool ideas of how I could apply my art to precious metals, stoked to see how it develops!
