|Monthly Tech-Tip |
This is more technically oriented than the first edition, a book for those who are really serious about "learning the glaze", rather than just "doing it". It has fewer glaze recipes, highlighting and explaining the really good ones and their special qualities of crystal shape, amount of crazing or maturing temperature. This book has more about firing, both gas and electric. And more about clay bodies and better information about the glaze materials, coloring the background and crystals, seeding the crystals and the firing schedules.
About understanding the process and materials. Mixing, applying and firing crystalline glazes is very different than with stoneware or porcelain. By far the best success is had by people willing to learn about materials and chemistry and experiment with recipes and firing schedules. A lot of things can go wrong and hundreds of firings are needed to develop a style and repertoire of glazes. There is even a "language of crystals" to learn, being able to describe things using the right terms is a big part of development and getting and giving help to the community.
