I have had a bottle of Spray A for a few years--I never get devit now that I stopped fire polishing on thinfire, so I have never used it. Recently I took a class where we were told that we should use Spray A when doing a certain technique because dark colors had a tendency to devit, so I wanted to go ahead and use it. However, I discovered that it had separated into a milky liquid and a hard white solid. I tried shaking it, but it didn't cause the solid to go back into solution. Any suggestions on how to fix this, or should I just buy a new bottle which will also languish in a drawer except when doing this technique? Thanks in advance for any advice!

It requires an extraordinary amount of shaking and agitation to get it mixed again, but it is possible.
Alternatives are saturated solution of borax or sprinkled clear powder or fine clear frit over the top of the piece.

I keep marbles in my jar of spray a.....lots of marbles.

Put it into a (microwave-safe) container you don't care about, stick it in the microwave and heat it to a simmer (not to a full boil). That should help it go back into solution, especially if you add marbles.

Aha! I was wondering if I could put it in the microwave--that's what I do with my kiln wash when it separates. Thanks everyone for the advice!

Are you sure you want to heat a solvent in an appliance which can ignite the vapors?
