Here's a few that I'm bringing to Maine Precious Metal Casting tomorrow. They will make a rubber mold of these metal pieces. When I order, say, 25 of a particular design, they will inject wax into the mold, sprue the waxes onto a wax "tree", burn the wax out in an oven/kiln, and inject the molten sterling into the negative space cavity left from the wax....Lost Wax Casting!!!
Yay for delegating work to worthy hands!!!
