These little beauties were made using PMC clay that when fired turn to Pure Fine Silver. My heart one would have had to be cast to get the same results if PMC was not available. The two with glass in them were fired in a kiln with the glass in place. The other one without the glass was torch fired. I may take one more step with the one that was torch fired, and add some contrast by using liver of sulpher. I'll post the results later.
