Using Foam instead of Wax Resist- update

Call me a creature of habit or set in my ways... I found it much quicker to use hot wax instead of the foam. If the inside of the foot ring is raised, the foam did not remove all of that glaze. Also any of the glazes with red iron oxide love to crawl into the crevices of the foam and stay there.

I did like the very straight glaze line you can get from using the foam.

Using Foam instead of Wax Resist

Chris, a potter from New Jersey, has been frequenting drop-in the past few months while he is staying with his sister in Truckee. He showed me how he learned to use a foam pad (consistency of a sponge) to wipe the bottoms of pieces on after glazing.

The idea is to glaze a piece, once the glaze is dry enough to lift with your hands, you push down and twist the piece back and forth on a moist piece of foam. The friction, caused by pushing and twisting, removes the glaze on bottom and up the side a little ways.

First we tried a fairly stiff piece of foam I had laying around the studio, it worked pretty well. Being it is on the stiff side, it only removed glaze about 1/8" up from the bottom. I love the straight line where the glaze has been removed. But, I want a little more clearance since many of my glazes can run and with drop-in pottery nights there are so many people using the glazes who are not failure with them.

Last night at drop-in, we tried foam from Wal-mart which is used for seat cushions. It is much easier to push down on but, does not remove the glaze as well. Some of the "testers" last night commented it took longer to then sponge off the glaze than dipping in hot wax.

I'll keep you posted on the results- last nights glaze pieces are in the kiln as I write this.

Let me know if you have tried something similar or other alternatives to using wax!
