Hi there,
I'm new here and wonder whether you could help me?

I'm setting off to make some silver earrings set with sapphires (I think these are durable enough to withstand firing in a kiln).
However, would you advise that I use PMC3 and kiln at 600 Celsius, or could I get away with the OneFire at 870-900 Celsius?
I'm not clear on the relative values of PMC 3 vs. OneFire? It seems that the latter is stronger and more easily manipulated (and since I tend to make fine detailed pieces I thought this might be the better option), but not if I can't set with stones.
Also, is it possible to use the PMC3 paste with OneFire despite different firing temps?

Many thanks for your patience with my beginner's questions.
Best wishes,
Katy
