Bob Coyle Posted July 2, 2014 Report Share Posted July 2, 2014 here are a couple of glaze tests I ran the other day fired to cone 05 on a stoneware body. the ramp held at 1150F for 30 min then to 1700F at 500/hr then to shutoff at 125/hr to cone 05 with a kiln sitter. Sample tiles have a black line drawn on the bisque ware and on top of the glaze to show slump and transparency. Glaze is brushed on with a second coat on the left side. I added talc to the standard "Jacky" glaze formula to get a little more hide and matte. The G20805 is not modified. Flecks in the glaze are unmixed pigments, since I just mixed them into the base mix and did not attempt to completely blend Jacky Mod 4 Flint 41.65Gerstley borate 27.58Nepheline syenite 10.84Lithium carbonate 9.51Talc 5.66EPK 4.76 G2805 Cone 04-06 Matte Frit 3134 44Dolomite 8Kaolin 12Whiting 8Silica 28 Link to comment Share on other sites More sharing options...

Denice Posted July 3, 2014 Report Share Posted July 3, 2014 Nice glazes, it's hard to get that earthy look in low fire. Denice Link to comment Share on other sites More sharing options...
