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.
