Duncan High Fire Index for Low Fire Glazes

This month I’m setting a goal to create glaze samples of all my “plethora” of random glazes I’ve accumulated over the years. Many of them have never been opened and some of them are over 5 years old…so this will certainly be a surprise.  


Since I fire to Cone 5/6 on stoneware, I’m interested in testing out my low fire glazes on this clay. Here is an index I received from Duncan describing the colors I can expect if I use their low fire glazes in a high fire environment. I thought others may be interested as well!! 

Happy Testing!
