  • Comes out of the kiln as sterling silver more than twice the strength of PMC Standard
  • Ideal for more delicate designs & for pieces that need the added strength
  • Due to the copper content in this formula, PMC Sterling requires a two-step process; step one is an open-shelf firing and step two requires a firing pan with activated carbon media
