Hi Snail, Thanks for the good advice. How do you wet your bisque before the first glaze coat. Do you dip it in water and if so for how long. Spraying with water might be another option but might not wet as evenly.

I find that deep narrow textures fill better when the first coat is thinned, and the bisque is well wetted. The glaze will wick down into the recesses more effectively. Subsequent coats may be dipped or brushed normally, and the glaze will tend to flow into the recesses, during firing following that initial thin coating; it will basically never flow where the clay is unglazed. For larger, sparser deep texture, I apply the first coat with a brush, using a stabbing gesture, then glaze subsequent cots normally, and it evens out nicely in firing. However, note that very narrow spaces may fill up entirely due to the same effect. This is nice for celadon-type glazes which rely on variations of glaze depth for their effect, but not so good for opaque and low-contrast glazes which rely on the actual, physical texture remaining visible.
