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?

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.
