- After bisque firing, keep your pots clean. Lotions, or even the oils from your hands, can create resist spots where glaze adheres unevenly or not at all. Throughout all phases of the glazing process, including loading and unloading the kiln, handle bisqueware with a clean pair of disposable gloves. If you think your bisqueware has been compromised — splashed with something, covered with grime, or maybe handled by a visitor — bisque it again rather than risk your glaze crawling.
- Remove all dust before glazing including bisque dust, studio dust and even household or street dust. Use an air compressor for foolproof results, but work outside or in a well-ventilated area away from your primary workspace, as bisque dust is extremely abrasive to your lungs.
- Use silicon carbide paper to remove any rough spots you missed before bisque firing. Place your work on a piece of foam to prevent chipping. After sanding, wipe with a damp sponge to remove all traces of sanding dust. Use a damp sponge instead of rinsing, which should be kept to a minimum. Wring the sponge thoroughly and rotate it so each area is only used once. I tend to use half a dozen or so of those orange round synthetic sponges during any given glazing session
