clayshapes Posted January 8, 2011 Report Share Posted January 8, 2011 I work in both earthenware and stoneware, and fire them separately. But am wondering... Since I bisque my stoneware to 05 and I fire my glazed earthenware to 05 as well (as recommended for the glaze I'm using at the moment), is there a reason why I can't fire them together. I read somewhere that glazed ware in the kiln changes the chemistry somehow and it's not a good idea to mix glazed with unglazed greenware. Any comments on that? And as a secondary question -- any reason why I can't put stoneware and earthenware into the kiln together for a bisque fire -- since I bisque them at the same cone?

Marcia Selsor Posted January 9, 2011 Report Share Posted January 9, 2011 You should test and see. Some glazes will react to a dirty burnoff from a stoneware bisque in the same chamber. SOme may not react. You can only try it and see what happens in your particular case. Marcia Link to comment Share on other sites More sharing options...
