Potters & Sculptors - Making Rock from Mud
Collaborate on building an online list of well documented glaze recipes, with application and firing methods. Strong photo documentation. Only glazes that are mature at cone 6 will be included.
Testing the glazes, and identifying their problems and fixing them. Also, if there are obvious issues just by looking at a glaze recipe (like high barium, insufficient clay to suspend or harden, too much feldspar (which causes crazing), too much clay (causing crawling, peeling), hard-to-get materials, non-specific materials, etc) then it needs to be fixed as part of the testing I would say.
Tony Hansen included links below to procedures for a few glaze tests that could be done. Another good one would be to appraise the rate at which it settles, how hard is the dry layer, the water content of the slurry, the viscosity, these could be measured with commonly available tools.

I'm setting up my new studio, mixing some glazes and get my first glazes unloaded. I was shocked at the Waterfall Brown as it wasn't anything like it had always been and I hadn't bought new…Continue
I found that I had a 2013 glazechem database.There are hundreds of recipes. I extracted the recipes for you folk. The files were so large that this software would not accept even one of them as…Continue
I have noticed that glazes often tend to either react when layered or are quite stable and do not mix. If anyone has any insights into the chemical reactions I would like hear. It seems like there…Continue
