High Fire Information
The high firing in our studio is done by our own trained volunteers, and is provided to CAC members at no additional charge. We use our electric kilns for this sort of firing, which accounts for over 80% of the firing in the Ceramic Arts Club. Our high fire is done to the Cone 5/6 range, which is 2150 to 2175 degrees Fahrenheit (this is the highest temperature that we fire to in the CAC kilns). It is the final firing, after glaze has been applied. Once a ceramic pot has been glazed with CAC glazes and high-fired, it is usually water tight (unless the piece has structural cracks) and food safe.
NOTE: Every piece must first be bisque fired (to cone 06) before it can be glazed and then high fired in the CAC kilns.
FYI: You may hear what is referred to as High Fire in our studio called "mid-fire" by people who work in other ceramic studios. This is because in some other studios they fire to cone 10 or higher.
