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.
I have been using the Amaco Obsidian layered with Potter's Choice colors for some really beautiful results. I have planned a new line around this. I had been warned that the dipped and brushed glazes combined don't work well together but I forged ahead anyway because I'm clever. I purchased the bucket of C-1 Obsidian, mixed it, dipped test pieces with it, let dry for 24 hours, layered the PC over, sure enough, crawling. I mixed some gum solution into a pint of it, brushed, layered it, normal results. I contacted Amaco and they have no workaround for me. They said they won't work together without the brushing gum and once the brushing gum is added I cannot dip with it. I know very little about glaze chemistry. Does anyone have any solution for my issue?
