I know you're right Calin! And I realized if I make one the right size I can fill up one of my many "bins" (which hold all my years of collecting "precious" art supplies) with water and let the pot "cure" in there, at my art studio, which would make it much easier to regulate temperature!! ( this was a very exciting idea that I came up with last week, and then you post these, and David posts his link...motivation for sure!)
