So, perhaps a bit geeky here, but one of things that drives me absolutely crazy in a group studio is the constant mess that is kiln wash. We've tried a number of different formulations in the past couple of years, and have consistently found nothing that behaves the way I believe a kiln wash should. That is, a kiln wash should last many firings, staying in place, and providing a decent barrier for glaze runs.
I recently found this recipe from Jeff Campana, and am anxious to try it in our studio. I thought it was worth the share...
