I use cone 07 for my bisque firings.
4. Bisque Firing
Each piece of stoneware goes through two distinct “firings” - a bisque firing and a glaze firing. The bisque firing is conducted at a lower temperature and takes place in an electric kiln. The basic flow of the process is as follows:
Typical temps for a bisque firing are about 1750 degrees (cone 07). Typical timeline is about 18 hours from start to finish.
