Bisque Fire question
So....
I accidently used Cone "4" to bisque fire a large number of vases, mugs, bowls etc.... Obviously I meant to use Cone "04"... Anyone know what the result is going to be? I'm going to do a test glaze fire shortly however I'm worried the pots are not going to accept any glaze. Thanks -Steve |

Thanks -Steve You won't get as thick a coat of glaze as the body won't be porous enough to suck up a normal amount of glaze. If you have a particular look for a glaze you probably won't get it. Best to go with transparent or flat glazes that will look okay thin. I saw pots by a novice who thought you had to bisque to glaze firing temp. She bisqued to cone 10!! High fire stoneware. Then she glaze fired to cone 10. Thin transparent glaze but they were glazed. We were amazed. Elaine |

Bisque Fire question
This actually happened in a studio I used to volunteer at (only worse -
fired to cone6). The glazes we use worked just fine. Getting the glazes think enough was a problem (people heated their pots, used corn syrup, glazed, heated, glazed again, etc.). Clear worked without any issue at all. Inside of bowls and such were easy enough to get think. Outside was tricky. These are for cone6 oxidation. I don't know if seeing them will be of use but here a few of them are.

Bisque Fire question
Steve,
We've met this one before! Our usual advice is to warm up the pots until you can barely touch them, then dunk them in the glaze. That way you get a much thicker coat than if you glazed them cold. The surface may be a bit frail, but if you add about 2 percent Gum Arabic to the glaze, that will help, and won't hurt when you next glaze some 04 bisc. Steve Bath UK In article .com, writes So....

Bisque Fire question
i have some pots that were no glaze, fired to cone 10, thinking the
clay body would look good. sometimes they do work nicely. we don't always have to glaze pots for a nice result. ~ but these were blah. so i glazed them & put them thru raku. ~ they came out great! the key was/is that the raku glazes were mixed on the thick side, the pieces had thin walls, and the pieces were fired slowly to give them a chance to heat up without cracking the clay body. see ya steve DKat wrote: Apparently my thinking about typos (collecting them for research interests sake) worked really well for generating data.
