Here is your chance to use the same Copper Matte Raku Glaze that William K. Turner developed after many years. William's glaze is the best, most fool proof raku glaze you will ever use.
You can buy my Copper Matte Glaze and all you do is mix it with water to make a about one gallon of glaze.
I use this one glaze to get more colors then most people get out of a dozen different raku glazes.
