This lidded jar form is made out of a fine porcelain and is finished with a gloss crystalline glaze. This piece is 12 inches tall and 8.5 inches in diameter.
Generally, crystalline glazes are fired in an oxidation atmosphere in an electric kiln. This glaze, however, has been reduced to shift the color from a cream-brown to a deep blue with lighter colored crystals. This is achieved by introducing a fuel/combustible into the electric kiln chamber at the end of the firing cycle. These combustibles deplete the oxygen in the kiln chamber so much so that it pulls oxygen molecules from the glaze layer and shifts the color from a light cream color to a deep blue or purple and produces gold and black crystals.
