During this workshop with Lois Hirshberg, participants will learn how to achieve dramatic results from this spectacular firing technique! In contrast to most ceramic firing processes, Western Raku is very fast. Combustible materials are smothered over the hot pieces after they are removed from the kiln. The vibrant colors and crackling of the glaze occur during this final smoking phase.

Various results can be achieved, ranging from turquoise to intense red/bronze to beautiful white crackle. We will also be experimenting with Horsehair Raku.

Western Raku is mysterious and elusive. The unpredictability of the process is what makes it so exciting!

You will glaze and fire your bisqued pieces outside in our two raku kilns. Everyone is welcome to this workshop, regardless of their level of expertise.

To safely handle and fit them inside the kiln, you’ll need 3-5 bisqued pieces made from Raku or white stoneware clay no larger than 10″ x 5″.

A saggar is a container that holds the ceramic ware as it is being fired in the kiln. In this workshop with artist Lois Hirshberg, we will explore methods of preparing and firing ceramic pieces in saggars to produce beautiful surface effects. We will experiment by loading the saggars with ceramic pieces surrounded by organic materials. Traditionally, saggars are made out of clay, but we will be using tin foil.

The purpose of the saggar is to provide an environment for fuming. The saggar is filled with a variety of materials, including seaweed, straw, sawdust, copper wire, salt, used coffee grinds, and more. The resulting color range includes blacks, pinks, maroons, oranges, and other colors depending on the ingredients used in the saggar.

We will then fire the kiln for several hours (until the tin foil turns to dust). When the ceramic pieces are cool enough to touch, we will remove them from the kiln and see what colors have emerged.

Each workshop participant should bring 4 or 5 small bisque pieces.
$20 materials fee to be paid directly to the instructor.
Please bring a brown bag lunch.
