Cone 6 Glazes / 6號錐氧化燒

On my previous post, I mentioned that two glazes on my tea pot – Orange Street and Creamy Rust are in Mastering Cone 6 Glazes. I think I was wrong. A blog reader couldn’t find the recipes from that book.
Here are the two glaze recipes I would like to share.
Just a friendly reminder!! Cone 6 glazes react to work-heat ratio slightly different from the cone 10 glazes. A different firing program could change how the glaze turned out from firing. Always run some tests on smaller pieces before you use them on your “real” works.
I fired my works in Cone Art kiln (have I ever mentioned that Cone Art is my favorite kiln since I was working for the porcelain company in Taiwan : ) with fast glaze program and hold at cone 6 for 20 minutes.
I got most of cone 6 glazes from Sawtooth School for the Visual Art, Winston-Salem, NC, where I am teaching an intermediate/ advance wheel-throwing class.
