C.C. Bookout The pottery displayed here by C.C. Bookout is thrown on the potters' wheel and is made of the purest white clay. It is porcelain in that its final firing reaches the temperature of 2385 degrees Fahrenheit. It is then cooled slowly over two days to help develop a crystalline structure in the clay and glaze. The glazes are ancient Chinese and Japanese formulations that pool over high spots in the clay to create a rich surface. The slip-trailed decoration is intended to accentuate this property of the glazes. There is color variation created by the different thicknesses of the glaze as it spills over the slip-trailed lines. The glazes are all colored by iron oxide or in common terms, rust. The different colors are created by the differences in the glaze ingredients and differences in the amount of iron oxide used. The blue and the green celadon glazes use only a small percentage of iron in a reduction atmosphere of a fuel-fired kiln while the tenmoku glaze achieves its rich brown color from a higher percentage of iron. The pottery is durable. It can go in the dishwasher and the microwave. If you do not break it, it could last forever. Think of all the pottery that exists today that was created many thousands of years ago. Thinking of this will give you a sense of how durable clay can be. elsewhere on the web:
