Bisque Distorting Pot
Posted 15 September 2010 - 06:29 PM
If the vase is round, you will probably get support from the curve, like an arch. So I wouldn't think it would distort.
If it is square or rectangular, you might have a problem, especially if the sides are thin(ish). Any side longer than four inches or so
might sag, and this might or might not be acceptable.
I have laid many round vases on their sides for bisque, and have not had a problem, bisquing to 04.
I think everyone tries to fit in as much as possible in a kiln run, only makes sense, no?
Here's Cynthia Bringle's bisque, at the bottom of the page:
And Gary Jackson's various kilns :

Not a problem, I have fired 06 bisque for years in a high school situation, and stacked the pottery in any manner I could get it in. Never had a warpage problem at that temp. Now When I fired an unglazed load to cone 6 for painting-that technique was a disaster on 3 pots.

I have had mixed results with distortion. In the interest of saving space, I pack it in, except for plates. I really baby them so they sit nice and flat. After having a special piece warp, I glazed it anyway and put it in the hight temp firing with great results! The warped bottom reformed itself into the original shape, and I got a flat bottom out of it. Was not so lucky every time, but worth a shot!
