Session 4: Foil Saggar Firing
Foil Saggar Firing
Saggars, or enclosures for pots, were historically developed to protect ware from firing ash or flame in a kiln. Today, they are most often used for the opposite reason, serving as containers with which to tightly pack combustibles or chemicals around ware. During the firing, effects from the added materials are concentrated and transferred to the adjacent ceramic surfaces.
In this saggar class, a simple, low temperature technique of wrapping work, colorants, and combustibles in aluminum foil packets will be used. Instructional demonstrations will include methods for wheel throwing closed (bottle neck) and simple lidded box forms, creating clean surfaces on the thrown work in preparation for applying terra sig, making and applying terra sig, preparing the saggars, and waxing and polishing the finished work. Students will gain information about the materials through several firings.
This is an intermediate level class, open to both wheel throwers and hand builders. **Students will be required to bring their own acid/gas respirator to use when handling chemicals and firing (you will need an OV/AG yellow coded respirator cartridge, not just a particulate cartridge).
Monday evenings, 6:30-9:30
