All the work is coil built and Raku fired. Prior to firing, some surfaces are burnished using various levigated slips. Biscuit firing is between 1000C & 1100C. The Raku firing is between 850C & 950C and is completed by a prolonged smoking and cooling process. Finally the pots are cleaned and where applicable sealed with a natural wax.
