The use of wax, paper, clay, and other materials to prevent the effects of heat, fire, smoke, chemical reactions, colors, and glazes from altering or contaminating the surfaces of work is very popular with ceramicists. However, learning to use these techniques can be a long and frustrating process, particularly when complicated by considerations of the state of the clay and the form of glazing to be used.
In this book Peter Beard discusses the techniques of masking and resist and gives guidance as to how best to use various materials and firing methods to achieve a wide range of finishes.
