DVD REVIEW- Glazing and Firing
March 24, 2010
Glazing and Firing begins with the basics: how to make and apply surface decorations and how to permanently change the composition of clay with the use of fire. In its most natural form, clay is nothing but earth, water and fire. Working with clay and glazes can be maddening at times, but with practice, experimentation and knowledge of the basic principles, desired effects may be achieved.
The DVD starts with a discussion on surface decoration. Beginning with clay in the wet stage (also known as greenware), slips, engobes, stains or oxides may be used as surface decoration before the piece is dried and fired. After the ware is dried and fired, the composition of the clay is permanently changed, and it’s now called bisqueware.
Discussion on the chemistry of glazes, as well as application methods, begins with the three basic components that form the building blocks of glaze, namely silica, flux and alumina. Mixing basics are shown and while it is very much like baking a cake, a certain procedure must be followed to achieve good glazes and the application process.
Next, we learn about methods of loading the two types of kilns: gas/fuel or electric (oxidation and reduction), and about how each kiln operates in regard to the creation of color. Finally, primitive methods for added special effects are discussed, which include pit/barrel and raku firings.
I think this is a great beginning on the basics of surface decoration and glazing, as well as an effective introduction to firing. However, I recommend that while mixing glazes, protective wear should include glasses, gloves and an aspirator.
