Sterling Silver Metal Clay
The latest issue of Metal Clay Artist Magazine is just out. In this issue Lisa Cain from MCSJ has given her method of making sterling silver clay. Lisa and her staff have developed methods, recipes and firing schedules for combining existing commercial silver and copper clay formulas into hallmark-quality sterling silver clay. A fired sample of the clay was first hallmarked by the London Assay Office on January 25, 2011.
Staff at MCSJ developed two successful recipes, one using Art Clay™ brand metal clays and another using PMC® clays. The clays were tested and the process refined to ensure that it could be reproduced easily and reliably in a home studio. It’s most generous of Lisa and her staff and promotes the evolution of metal clay.
Even though Mitsubishi have marketed PMC Pro being 90% pure silver and 10% alloy the public in general have been confused when it comes to jewellers marking and selling their work.
