This is an ongoing log of clay materials and firings to compile the information I have collected over the 20 years making pottery. I would love to make this into a book at some point, but until that happens, here it is for all to see and investigate.
My Initial thought is to split this into clay, glaze and firing sections and organize as I go, but I’ve decided to see what I input first and then I will organize them later. So please understand that this is not in a particular order at present.
The way I look at clay and glaze is they are the same materials organized in different percentages and ways to satisfy specific requirements. Clay usually needs to be the substance of ceramics and glaze is the coating in or around it, but as the art of ceramics grows this perception is being challenged.
