synj00 Posted November 11, 2014 Report Share Posted November 11, 2014 I'm seeing a lot of recipes for feldspar / granite grog or manganese to get the dark spots in the lighter clay that bleed into the glaze. Is there an inverse where you take a dark clay body and add something to get white or lighter speckles? Lighter color grog would work but want something that bleeds into the glaze a bit. (preferably without creating pinholes) Link to comment Share on other sites More sharing options...
bciskepottery Posted November 11, 2014 Report Share Posted November 11, 2014 This is Standard 266 with feldspar inclusions, no glaze. Have not tried any glazes over the feldspar. Basically, pea gravel size custer feldspar that is sledge hammered down into smaller pieces/dust, then sprinkled onto slabs. Light soda ash wash (1/6 cup soda ash dissolved into 1 cup hot water) applied. Fired to cone 6, oxidation. Link to comment Share on other sites More sharing options...
MMB Posted November 11, 2014 Report Share Posted November 11, 2014 Molochite can be used to give a white grog look. Its very dominant at about 15% when the surface is wiped away just slightly. I have a ton of granite dust that I want to experiment with in a dark clay body like you. I cant find my test tiles with the molochite in it anywhere!! I think I trashed them because I wasnt happy with the body, not the molochite. Link to comment Share on other sites More sharing options...
