Glaze Inspiration?

My friend Graeme of Arcimboldi Studios made a post on FB where he was experimenting with Copper, Salt and Ammonia. It makes a fantastic patina.

Long strip soaked (right) overnight. other 2 place a small amount of ammonia in a small container like bottle top place in tupperware box. Sprinkle salt over brass sheet randomly and cover tupperware box for about a week. Don’t breath in:-)

I’m wondering if it is possible to add a small amount of salt to a glaze with copper oxide and see what it does. Or placing small salt crystals on wet glaze. The box of things to try is miles deep.

Potters of Japan Documentary

I’m always interested in the older pottery videos of times gone by. My wife and I enjoyed watching The Potters of Japan the other night. Put together by Richard E. Peeler who was a pioneer in documenting these treasures. It features some the great pottery styles and regions of Japan like Bizen, Tamba, Haki & Mashiko that we saw during the visit to the Mason-Scharfenstein Museum at Piedmont College. The soundtrack is just classic!

Celebrating Failure

Pretty much everything that could have gone wrong with this last firing has gone wrong.

Clay body cracks
Crazing

Crazing reduces the strength of the vessel by up to 80% A short drop to the wooden floor split this right in half.
Blistering AND crazing

Pinholing AND Blistering
Pinholing like a CHAMP!
Even a bit of reduction in part of the kiln. Although I must say the reduction looks beautiful!

I’m picking up some dry materials to start testing my base glazes. At least I know that my chosen clay body tolerates overfiring very well.

I’m getting some witness cones (5, 6 and 7) to stack on each shelf and see what they do. I don’t understand whats happening yet. Olympic says that the kiln usually underfires if something is wrong rather than overfiring. The company that makes my clay body says that blistering happens from overfiring. The cones should tell the tale though. I need to get that straight before I drive myself crazier than usual.
