Although similar in appearance to some Raku processes, vapor glazing differs in two ways. First, since no copper is used in the glaze the brilliant colors will never fade. The pots have about 25 to 30 thin coats of glaze applied, then fired in an electric kiln. Second, instead of a post firing reduction, as the kiln cools down metallic chlorides and nitrates are introduced. The chemicals vaporize and the swirling fumes coat the pots with iridescent colors, similar to the production of iridescent glass. It's a tedious method, and like Raku, only two or three pots can be fired at a time, but the results are magnificent! |
