The images appearing on these pots are formed solely by applying the tin white, and in some cases, coloured glaze to the bisque. The black areas and linear work is the consequence of leaving the area of clay body free of glaze. The thinnest of lines is the result of brushing the glaze to within a millimetre of its adjacent area. Temperature is crucial here as when the glaze matures it will run and quickly merge, so loosing the line. Only when the piece is taken from Raku kiln at 1000º and smoked in a chamber of sawdust and wood shavings does the carbon deposit form and complete the work by turning the unglazed areas black. Once there is sufficient coverage the pot is removed before scrubbing and washing in water.

If you ever get the chance to watch or participate in a Raku firing, grab it. It's always outdoors, very hot and very exhilarating!
