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 them, only buy brushing bottles and using distilled water. I need these glazes to work in dipping form for my students. I have used distilled water, it does not make a difference. I have thinned down the glaze, doesn't help. I have tried applying the glaze with time drying in between each layer and also dipping them one right after the other, doesn't help. Does anyone have suggestions? Thank you.

When a manufacturer states that a specific line of glazes is 100% mixable, and that each of these glazes is food safe on its own, can I assume that means that if I layer or mix colors in the same line the glaze is still food safe? Applied and fired according to their instructions of course. I'm really agonizing over glaze safety and no, I don't want to make my own glaze. The prevailing wisdom, and what the manufacturer's say, seems to be that once different food safe glazes come in contact with eachother, all bets are off as to the food safety of that glaze. This makes sense to me, but I'm seeing all sorts of combining going on in utilitarian ware. Beautiful combining. I don't think everyone is sending their stuff off to the lab for testing. Or maybe I'm wrong. At this point I'm using single glazes anywhere food touches. I'd appreciate any guidance and suggestions. Thanks Irene, trying hard not to contaminate anyone or make any enemies
