A possible contributing factor to bubbling is the firing temperature of your first opaque cycle relative to the oxidation cycle temperature. If you are oxidizing the alloy prior to opaquing, even if you then blast off the oxide layer before you apply...[More] opaque it is very important that your first opaque...

I agree with Jeff. It's likely contamination of the metal from finishing stones.

If any of the metal from the machined...[More] gold interface gets into the stone, it can no longer be used for finishing.
