Bob Coyle Posted February 18, 2014 Report Share Posted February 18, 2014 Here are some photos of test tiles I made using a recipe taken from the October issue of Ceramics monthly. It makes a pretty nice waxy magnesium matte. It is stable between cone 5 and cone 6 and holds well without sagging with good leveling on the pot. This is important to me because I brush on all my glazes. This was a straight up run with a shutoff at cone 5 with a kiln setter. the last part of the ramp up to shutoff was 125 F/hr from about 1700F. The glaze was used on the tree pot which is speckled buff.

Roberta12 Posted February 19, 2014 Report Share Posted February 19, 2014 Nice glaze, Bob. And very nice tree pot! How did you do the tree design? Apply it after the pot was thrown or carve it out on the pot?? Roberta Link to comment Share on other sites More sharing options...
Bob Coyle Posted February 19, 2014 Author Report Share Posted February 19, 2014 The tree was incised in the leather hard pot then it was bisqued. I masked the tree and glazed and fired the pot. Then I electroformed copper into the incised tree and patinated it. Link to comment Share on other sites More sharing options...
