In the past, after sieving them out, I’ve tried to heat up the crystals with boiling water, or then in the microwave. But when added back into the glaze they form again. The glaze works without the crystals (I got about maybe 2 cups of crystals sieved out of 1-2 gal glaze), but it’s not as interesting.
