Coyote Clay & Color

FYI, I am a university trained ceramic sculptor with over 50 years experience. If you are reading this you likely already know that Coyote Glazes produces a line of ceramic glazes for a variety of firing temperature. I purchased several of their cone 6 glazes including a shino glaze and they all worked well. Several months later, I went to use them again only to find that the shino glaze ingredients had formed small hexagonal crystals, thus rendering the glaze useless. In all my years in ceramics I had never heard of or seen this happen. I contacted the company about the problem and they explained that it said on the package, (in very small type), not to store below 65 degrees. I pointed out that something that important should have a more highly visible label. The owner agreed and sent me replacement product at no cost. Yet again my faith in humankind is reinforced.
SUGGESTION: The thickness of the liquid glaze in the bucket is very important for consistent and predictable results. If you don't know already, find out what a hydrometer is and learn how to use it. Forget the-glaze -should coat-your -hand business.
