Each piece is fired in an outdoor kiln to 2000 degrees F. It is then pulled from the red hot oven and plunged into a sand pit with wood shavings. The red hot vessel causes the shavings to ignite. After the flames reach their maximum height, I cover the inferno with a metal drum. The unique manner in which the fire burns each time creates the unique splashing of colors from the copper glaze on the Raku art piece. The intense change in temperature from the red hot kiln to the outdoor atmosphere shocks the glaze, causing cracks. The smoke penetrates any unpainted parts of the ceramic art, turning it black. The black lines in the crackle are from the smoke penetrating the fissures in the transparent glaze.
No two pieces are alike
Ceramic art made by hand will have minor variations in size and shape. Due to the varying conditions of the Raku process, each piece is unique. No piece will look exactly like the picture from the catalog or website. The colors in copper matte vary and may include: copper, blue, silver, gold, magenta, green and brown. Despite efforts to create the most beautiful Raku finishes possible, occasionally some items will arrive with minor imperfections such as small scars, specks, cracks or pin holes in the glaze. These imperfections are unavoidable in the Raku process and add to the character and uniqueness of the Raku art piece. Copper in the matte Raku glaze may react over time in the atmosphere and could slowly turn green. To best preserve the finish, Raku pieces with copper based glazes should be kept in a dry environment and out of direct sunlight.
