pots from one bisque load

work, work, work!  the sale approaches!!!!
I've unloaded the bisque kiln and am about to wax the bottoms of all the pots (and the lidded areas), so that I can glaze everything.  Here's the procedure:  before I glaze, I wax, then wait for the wax to dry, (the longer, the better), then dip everything into a bucket of cool water (don't want to re-soften the wax), then wait til the pots dry a little and can accept the glaze, and then I glaze.  If the pots are too dry when they're glazed, they absorb too much of the glaze water, too quickly, and the glaze builds up unevenly on the surface of the piece, sometimes pinhole-ing and leaving areas that are too thick. In addition, I single-dip, so I can't re-dip where I think there might be a problem. On the other hand, if there is a little moisture in the pot (just cool when held up to your cheek--as you would a bone-dry piece, to see if it's dry enough to go into the bisque), then the water from the glaze enters the porous, bisqued walls a little more slowly, and the air exits less precipitously, and I don't have little pinholes all over the glaze (which have to be fixed before firing, so they won't show up, later.)  hmmmmm.  If you have questions about this  (better as a demo, I think) just ask.

  1. Thats a lot of pots! I'd heard of this technique before but wasn't really sure about how it worked. Thanks!
