OK. I decided to bite the bullet and sit down and type these in. I had
many requests. If I didn't respond to everyone, my apologies. I said I'd
post 'em and here they are. There are 14 with many variables. Read the
attached microsoft text only document.These are ^6 glazes which look
like ^9 stoneware glazes. We have used them for 20 years. I had to go to
^6 when we moved into a new building. I was told to conform to an 8 hour
firing for the assistant's work day. I had an assistant for four years.
The last 14 years we have still used these glazes.
Best wishes,
Marcia Selsor, Professor Emerita
