I don't have the glaze calculation software, but would rather not publish this recipe online. But thanks for the tips. If you google Margaret Kunzler you can get my information on Siskiyou Arts Council webpage. Another question I have about possible changes in this glaze is the barium. Is there a big difference between Chinese barium and German Barium? Another possible problem is that I added a little chlorine bleach to the bucket because of growth of green slime. (Could this affect the glaze?) I'm going to run a bunch of tests. I will also try G-200 feldspar. Strangely enough, this matte glaze has become more melted with Custer. I'm thinking of removing some of the flux.
Thanks again, Margaret
