Komakigama

When I was 17 years old, way back in 1974, my first introduction to ceramics were Shigaraki jars that were wood-fired and made with clays ladened with decomposed granite.  Read more here..

The Deep Stillness of a Raku Tea Bowl | Nippon.com

Black Raku chawan, or tea bowls, are currently gaining global attention. The founder of the Raku family of potters created this implement at the request of Sen no Rikyū, who elevated the Japanese tea ceremony to entirely new levels of refinement. What is the allure of these tea bowls that crosses national borders? We asked Raku Kichizaemon XV, the current head of the Raku family, about their appeal.

Have you ever wondered what causes “flashing” colors on bare clay in atmospheric (e.g. wood, salt or soda) firings?

Pots from Feb 3 2016 Stanford Kazegama firing

http://firemouse.me/stanford-kazegama-february-3-2016/

Firing was 6 hours in neutral/oxidation to reach cone 9, then ash introduced gradually over the course of a 3 hour reduction soak dropping cones 10/11.  Firing ended with a 3 hour reduction cool down to about 1850F.

A more gradual introduction of ash…

20160202_155429_resizedYesterday we fired the Stanford kazegama again and tried a new method of introducing the ash.  Previously we fed the ash into the intake of our large combustion blower, following Steve’s original method, and this worked well except that many pots ended up with unfortunate clods of unmelted ash.  In the above photo you can see a metal sealed can with a red rubber hose and larger diameter steel-mesh hose attached to the lid (the upside-down white plastic bucket isn’t doing anything).  We put ash into the metal can, blow compressed air in through the red hose, and allow a well-dispersed stream of ash to enter the burner through the metal hose.  The can is loaded only half-full with ash, and we didn’t screen the ash ahead of time.  Some shaking of the can is necessary but the ash goes in gradually (we put in about a gallon over the course of about two hours) and without clods.  Larger pieces of “sintered ash” get left in the bottom of the can, and probably help stir up the finer ash when shakin.  You could do the same thing with any sealed container with bulkhead connectors.  The can we use has 1/4″ NPT fittings.

Kazegama Rebuild – January 2016

For 15 years, my Kazegama was bolted to a trailer which allowed me to travel to different venues to put on Kazegama workshops. It has gone through many adjustments and changes due to the knowledge gained over many years of firing. Continue reading
