The test tiles seemed to turn out pretty well, but the glaze on this test mug didn't see to do as well. The mug is made from a white cone 6 stoneware, where as the test tiles are buff stoneware coated with white slip. I'll need to test this glaze further to see if I can isolate why the mug bubbled so badly and the tiles didn't.
Something to working on tomorrow I guess. Have a great week.
