LeeU Posted June 4, 2017 Report Share Posted June 4, 2017 I have maybe a half shelf or a half and a bit more of "smalls" in an unglazed cone 10 Troy Woodfire body. If I only fire it to cone 6 (for bisque) and I am not able to get into a woodfire anytime soon, and the peices are not being used for food or anything that would get much handling, will that clay be "fired enough"? Or would I be shortchanging myself re: quality by not just holding on to them until I can do a cone 10 wood fire, or even just wait until I can make enough from a high fire body to fill my my electric kiln? I can afford to wait, but I'm not really all that patient if it doesn't make a major structural or aesthetic difference for the type of ware. So-what should I expect-usable at 6 or not until 10?

Marcia Selsor Posted June 5, 2017 Report Share Posted June 5, 2017 usable in what way? If for water, it may seep. If it is sculptural, not a big problem except the glaze might craze. Marcia Link to comment Share on other sites More sharing options...
glazenerd Posted June 5, 2017 Report Share Posted June 5, 2017 You can fire to cone 6; understanding that it will be in no way way functional. I use to fire cone 10 porcelain to cone 6 all the time, when I began moving my crystalline glaze to a friendly firing schedule. The fluxes used in cone 6 and 10 are exactly the same: there is just less of it in a cone 10 body. You can cheat it a bit if you wish: after you bisq fire: spritz or dip the pieces in a mixture of 1 tablespoon of Nep Sy to one cup of water. The additional flux absorbed with help increase vitrification and help stabilize the clay/glaze interface. Nerd Link to comment Share on other sites More sharing options...
