- "How do you apply your glazes?"
There are several ways of applying glaze. Dipping the piece into a large bucket of glaze. Pouring a thin, liquid glaze onto a piece. Spraying on a glaze. Or Brushing on the glaze.
I almost exclusively use the brush method. Whether it is a glaze, slip, underglaze, or oxide, I prefer to use a brush. Since I apply multiple colors in specific areas, brushes give me the ability to control placement and composition.
- "I brushed my glazes, but they didn't crawl like yours? What happened?"
Well, one of the biggest "secrets" is to mix and apply these type of glazes THICK. And by thick, I mean like cake frosting. It isn't a matter of "How many coats?". Usually, just one "frosting" will to the trick. They end up being about 1/16" - 1/8" thick. (Another reason brush application is preferred over other methods.)
When the glaze has dried on the bisque ware you should see the crackle or crawl pattern. This is also when the glaze is the most fragile, and tends to chip when over-handled. (Right photo below.) When using crawl glazes in combination with non-crawl glazes, I apply the crawl glaze last, and then immediately load it in the kiln if possible.
Another tip: Be mindful of the direction you apply the glaze. This crawl glaze will tend to pick up brush strokes. Where the glaze is the thickest, the crawl beads will be larger. Thinner glaze = smaller beads.
