This may be a harebrained idea, but…
I have several sterling bracelets that I need to heat harden. I’ve
never done this, since I don’t have a kiln. I was looking at the Rio
catalog’s advice on the subject, and they said I need to get the
silver to 600� F. for 30 to 50 minutes.
I will soon run the self-cleaning cycle on my electric oven, and 600�
is about the cleaning temperature. But it stays there for longer the
50 minutes, I think. Would it be at all feasible to put the silver
pieces in the oven? What would happen if it stayed hot for too long?
