1 firing can be either bisque firing or glaze firing, and it depends on the current status of your pots.
(If this is not sure, please check the information from the first page.)
2 firing means you need to fire bisque and glaze firing respectively.
Please note that glaze firing options are only our communal firing.(1,260c)
If you need to fire the kiln separate with other temperatures, pleas tick "other"
