Diamond Glaze Problemos

There has been a recall on Diamond Glaze. I forget the batch number, but it affected the November 13, 2008 batch. During the drying process the glaze cracks. I've heard others tell that they've had the same problem with batches that WEREN'T recalled. I found a way to ensure that the glaze doesn't crack. When the glaze dries, room temp should not go below 70 degrees F. Since it's still cold where I live, I put my pieces to dry on a cookie sheet and lay them next to a heating vent. NEXT TO NOT DIRECTLY ON IT! Just as long as your drying pieces stay warm, you should be fine.
