I am having trouble with Amaco's Potters Choice glazes crawling when layered. I have used them for years and have never had a problem until about a year ago.
The issue is specifically when layering the potters choice glazes in dipping form. The Brushing bottles are fine, I have not problem with them.
At first I thought it was my students application or the thickness of the glaze. But after endless test I can not figure out what is going on. I called Amaco and they said they were aware of the problem and were working on it. But the only suggestions they had were to stop layering
