  • Dense and still fires fast
  • Fires at remarkably low temperatures
  • Three distinct firing options
  • Greater firing range useful for co-firing glass, findings and some stones

PMC3 Technical Information

When fired at 1,650° for two hours, PMC3™ is the strongest fine silver metal clay available. It has a finer, smoother composition that’s easy to work with and manipulate. You can also embed findings with confidence—firing at a low temperature means they won’t be heat-damaged. PMC3 is suitable for torch-firing as well as kiln-firing.

Best ways to work with PMC3

1 Strongest fine silver clay with smaller, more variable metal particles

2 Useful where strength is required such as rings, bracelets, bails and small, connecting parts

3 Variety of firing temperatures which are one low enough to embed findings, glass elements and low-fire stones

4 Suitable for torch-firing as well as kiln-firing
