The figures are first bisque fired in an electric kiln. A white crackle glaze is brushed on and fired in raku kiln to 1000degC at this point the lid is removed from the kiln and with metal tongs the red hot figures are removed with metal tongs and placed into a tin bucket of sawdust. Flames flicker on contact with the extreme heat of the ceramic form and a lid is placed on top shutting off the supply of oxygen.
Once cool the pieces are removed from sawdust and washed to remove ash and sawdust. The effect is the glaze has formed crackles and the black markings is the carbon from smoke entering the surface of the clay and cracks in the glaze.
