This cone 06/04 clear glaze has a smooth satin finish and is ideal for covering underglaze designs. It should also be applied thinly as it may cloud if applied too heavily. It is lead-free, dinnerware safe, A/P non-toxic and also zinc free. These cone 06/04 glazes provide solid coverage and a beautiful satin finish. They require 2 to 3 coats by brushing. Satin glazes tend to be stiffer and do not move much in firing, so an even application is important. They are sensitive to the firing temperature, in that the hotter they are fired the smoother and glossier the surface will become. They are all lead-free, dinnerware safe and A/P non-toxic.
