“Copper Flash” Raku is created by applying a “copper matt” glaze to the bisque-fired clay. Each glazed piece is returned to the kiln until the proper temperature is reached. One by one, each pot is removed from the kiln with tongs and immediately submerged in a container filled with combustible materials (such as sawdust and/or shredded paper.) The materials ignite, and something magical occurs. As the flames lick up against the pots, they react with the copper matt glaze, producing colors that are nearly impossible to achieve with standard glazes. The process is ended by putting a lid over the container at the proper time to extinguish the flames.
My black and white vessels are achieved by polishing the clay surface, heating each piece in the kiln and removing them while they are red-hot. Strands of carbonous material are applied to the surfaces to create patterns.
