Here is a kiln shot of the second firing of the semester.

I wanted to test the use of a black underglaze under a grolleg terra sigilatta on the different clay bodies that I am currently using. I am satisfied with some of the results, especially the cup at the bottom of this photo.

A few of the pots I am not satisfied with, the glaze over took the images; Clyde or Morty, the sandblasting guns, may have some work lined up for them. Plus, I think it is time to move away from these drawings, as much as I love them.

Gabe had a tile and some chopstick holders on the top shelf that turned out really nice. The tile bloated in a couple of spots which creates a nice break in the repetition of stripes.

On September 6, I fired a cone 10 soda kiln with a neutral atmosphere. It was primarily so I could get some glaze and clay body test results. Julie helped me during the firing so she could learn about firing Badda Bing, and she got some great soda texture on her porcelain cups. We added one pound of soda ash to the kiln through a garden sprayer.

Results of my clay body tests, (l to r) red stoneware, dark brown, and stoneware with yellow ochre addition. I am happy with these results, especially the YO Stoneware in the soda.

Below are some glaze tests from this firing. They are on a different red stoneware body than the one I tested above. These three turned out the best, yellow and lavender have some potential.
