Traditionally potters fired their work either at low temperatures, as for earthenware, or at the high temperature that stoneware requires. However, a growing number of potters, particularly those who use electric kilns, are firing to a middle-range temperature, of which cone 6 is typical. Using middle range temperatures saves fuel and expense, reduces wear on electric elements, and yet allows the potter to achieve features shared by earthenware and stoneware. Because of the popularity of this technique, pottery suppliers have recently begun developing clay bodies and glazes suitable for the temperature range.
In "Glazes Cone 6" Mike Bailey surveys the growing trend in middle-temperature firing and guides the reader by practical knowledge. He discusses a range of different glazes, including special effects, glaze stains, and underglaze colors, giving both recipes and tips for ensuring success.
