Gas Car Kiln, 2008

Robert built this kiln in 2008 after deconstructing his previous kiln built in 1977. He made many improvements over his previous gas kiln.
The gas kiln at Robert's studio is used primarily for bisque firing, as most of his work is fired in one of his wood fired kilns. However, he does high fire the gas reduction kiln to touch up pots that may have been under-fired, or had un-melted ash deposits from the wood kiln. He also uses the gas car kiln for special glazes such as Copper Red or Carbon Trapped Shino.

Design Elements

The large 6" wheels on this cart allow it to be rolled in and out of the kiln easily using a metal handle that screws into the frame. Robert's previous gas car kiln had 4" wheels and it was necessary to winch the cart in and out.

Gas Car Kiln, 1977-2007

Robert built this kiln in the mid 1970s when his primary business was making Aquariums and Fountains. It was fired weekly for many years.

Firing The Kiln

When Robert built his first wood kiln in 1993, the use of the gas kiln changed and began being used primarily for bisque firings. It was fired over 500 times during its tenure at the pottery.

Unloading The Kiln

After the firing the glazed pots show the variety of reduction in the kiln chamber.
The darker reds show the areas of the kiln that experienced more "reduction of oxygen" during the firing.

Gas Salt Kiln, 1994-2000

This Gas Fired Salt Kiln served Robert well for six years. It was demolished in March of 200 to make room for his 250 cubic foot Noborigama Wood Kiln.

All of these kilns have been dismantled. The building was taken down and then doubled in size to make room for the Noborigama 250.

Gas Fired Two Chamber Kiln, 1974-1977

This was Robert's first kiln at his Bristol studio. Constructed entirely of insulating fire brick, it incorporated a two chamber design. The waste heat from the first chamber was used to bisque fire green ware in the second chamber.
