Looks great Swizz! Because a mug can last forever and so does lead, I like to write "NOT FOOD SAFE" on the bottom when appropriate. This guy's great grandchildren could end up with lead poisoning when they discover this mug in the attic 100 years from now and use it to drink from :lol:

You are sure having your share of trouble with glazes, don't get discouraged! Everyone else has put their 2 cents worth in, I might as well add mine: Are you using a cone pack to be sure the kiln isn't over or under firing? Are you able to try a slower cycle so the kiln has more warm up and cool down time? Could be a Glaze Fit problem Are other people in the class using the same clay/glaze combination? Are they having problems too? I was told I could use low fire glazes on a high fire clay body fired at low fire - but I got shivering (chunks of glaze coming off) every time I tried it. I realize you may be limited in your choice of products, either in the school or available in Australia, but you might want to try another slip or glaze. The other (much more complicated) option is to put additives in your slip or glaze, I'm afraid I don't know much about that but the information is out there.

Keep pluggin' on Swizzle, you'll find the right combination!
