We had a workshop in Wildacers NC through the FSG, Fall 2009.
This is the project I demo in the workshop. We experimented in different backings and each artist chose which method they preferred. In this jewel I use pure platinum foil to support the enamels while firing. Hauser Miller will roll this for you to.002 ”
A draw back is the expense of the platinum, but it can be used multiple times and sent in for refining. The advantage of using this foil over other backings is the end result of clarity in the enamels.
