RAKU WORKSHOPS


Escape the hustle and bustle of city life and immerse yourself in the slower pace of Northern California.

Enjoy hand made snacks & lunches while learning about building outdoor kilns and alternative firing methods during the day.


Kilns and Alternative Firings



Wood Fired Train Kiln


What is a Train Kiln?

The original design for the train kiln comes from John Neely, Professor of Ceramics at Utah State University.  It gets it name from how the firebox (the fuel center for the kiln) and chimney are purposely constructed at the either end of the kiln and resembles a train engine. The firing results of a train kiln are meant to mimic an anagama kiln, but is much easier to fire. 

What is Wood Firing? 

Wood firing is one of the oldest processes to fire ceramics. Wood is used as the source of fuel to climb in temperature. Up until now CBTB has been using electricity to fire ceramic ware. The kiln gets SO hot (about 2350 degrees F) that the wood ash from the wood actually becomes the glaze on the pottery/ceramic ware! The kiln must be loaded for one day, fired for two days, and then cooled for up to a week. Then it's ready to unload all of your beautiful work! CBTB is doing our part to maintain the natural forests of Nor Cal and will be sourcing wood from sustainable sources (end cuts from wood suppliers, cabinet makers, etc.).  All wood-fired work is dishwasher, microwave, & food safe.

Atmospheric Firings


What is Pit Firing?

 

Pit firing is the oldest method for firing ceramics, dating back nearly 30,000 years ago.  First, a hole is dug in the ground and pots are placed in the pit with layers of organic matter, combustibles, and other additives and burned. The burning wood creates an atmosphere where smoke and vapor swirl around the pieces in the pit, creating surfaces that cannot be recreated.  Pit fired pottery is for decoration only and not food-safe.

What is Raku Firing?

Raku is a low-firing process that is inspired by traditional Japanese style of firing.  Pots are heated up rapidly and removed from the kiln while at a bright red heat.  The glowing pots are then placed into metal containers with combustible organic materials. Once the pots come in contact with the containers, the materials instantly ignite and the containers are sealed. This creates an atmosphere which reduces the amount of oxygen within the container, creating totally unique pots that have flashes of bright colors and a crackling effect.  What's FANTASTIC about this process is that you can have a piece of bisque fired pottery come out of a glaze firing in just under 2 hours!  Raku fired ceramics are for decoration only and not food-safe.
