The unique finish on the piece is achieved with a raku glaze that contains minimal amount of copper carbonate. The wheel thrown bisque fired pot is glazed, then placed in an outdoor raku kiln and takento a temperature of 1850. Quickly the artist removes the red hot pot and places it in a metal container filled with straw. THe hot pot ignites the straw, and the smoke and carbon react with the copper to create exquisite rainbow of carival colors. The necks on the bottles are treated with a silver nitrate glaze creating an extreme luster effect. When cool enough they are finished with a hand finishing.
