What is a raku glaze?
Similar to the question of raku clays is the answer to this question. Any glaze that you can successfully raku fire is a raku glaze. The most important factors in identifying raku glazes are the temperature at which they mature, how you plan on using them, and what kind of effects you are looking for. You must also keep in mind that if you are using a variety of glazes on the same pot or in the same kiln load, unless you know that they all mature to your satisfaction at around the same temperature, you will be faced with varying degrees of maturity. However, just because a glaze is formulated to fire at a temperature higher than your usual range doesn’t mean that you should eliminate that glaze from your pallete. Experiment with your glazes to achieve a variety of surface effects from dry textures to surfaces with a high gloss. Don’t limit yourself to homemade or personal glazes either. Try low fire commercial glazes for some unusual results.
