Firing Results

We fired the soda kiln at the Watershed Center on May 2, and just unloaded it today. This was our second firng in this kiln, and we definitely improved on the first:


As usual, I find the bottoms of bowls almost more handsome than the rest.

One great addition this firing was the use of Bauer Orange Flashing Slip:

41.9 EPK
41.9 OM 4
5.7 Borax
10.5 Zircopax

Apply very thinly to bisque. Works on greenware, too. Do not apply over glaze.

This week:
Monday -- Beginner's Class, Portland Pottery
Tuesday -- Fiona getting spayed! Find sub for Intermediate class.
Wednesday -- Trim lids & finish casseroles

May 3 Firing

The last time we fired this kiln, we had a tough time keeping it in a sufficiently strong reduction. This I blamed on a very loose door of castable bricks, so we took steps after we loaded to address the problem. Using door mud (50% fire clay, 50% alumina) we filled in the gaps, then papered over the door with newspaper dipped in a slurry of recycled clay:




Relaxing while waiting for cones to fall:

Adding the soda mix:

We had no trouble reducing this time! Unloading Sunday. In the pouring rain, probably. I'll keep you "posted."
