sorry, its bisque to cone 06. this is the glaze i'm looking at:
Duncan Crystals & Crackles Glazes Celadon Crackle
but it needs an 04 bisque... does anyone know of a glaze that would work with a 06 bisque?
I bisque to cone 05. Some porcelain users will bisque much lower. The main difference is how absorbent the bisque will be when glazing. Many studios bisque at cone 05 or 04 to help reduce glaze runs by less experience students. A higher bisque temperature also helps burn out more clay impurities that could affect the look of a glaze. You may have to experiment with glaze thickness since your bisque is lower and the bisqueware a bit more absorbent. Go ahead and use the Duncan. Make up a handful of test tiles and go for it.
