Session 4: Cone 6 Soda Firing, Wednesday pm
Cone 6 Soda Firing (Session 4)
This class offers a hands-on opportunity to make, design and participate in the firing of pots in a soda kiln. In the soda firing process, a soda ash (sodium carbonate) and sodium bicarbonate solution is sprayed into kiln at maturing temperature, and the sodium vapor combines with the silica in clay to form a sodium-silicate glaze. Surfaces textures vary from juicy gloss through satiny-smooth to pebbly and dry. Since the soda provides the glaze, surface decoration focuses on the use of slip, textures, and accent glazes as well as the raw clay surface, rather than glaze interactions to create interesting surfaces. Students new to soda firing are welcome. All students will need to have taken a previous introductory clay class (either throwing or hand building), and all students are expected to load and unload the kiln as part of the class. Cost includes firing fee.
