Making two sectional long neck vase and pitcher. I threw the bottom part last week, and dried very slowly over the weekend. The bottom part is about 15″ high. I threw a chuck, and dried quickly with the heat gun, and trimmed the bottom. Then I threw a cylinder, about 10″ high. I placed th trimmed bottom part on the Griffin Grip and placed the cylinder on it, and threw it. I usually place a paper towel inside the pot to collect the throwing water, to be safe side as the bottom part is already trimmed (some part maybe is thin). They are about 24″ high now. It will shrink to 21″ or so after the glaze firing.

Bisque firing was completed. So problem was related to the thermocouple.

I hurt my hip, and pay a visit to my chiropractor today. Take easy for next couple days.

I tested elements of the electric kiln last week. I set the kiln to “the fast glaze”, and turned on for 30 minutes with the lid open. All elements are lit, so the elements are fine.  I checked the thermocouple, and replaced one in the middle with one in the top, and placed a new thermocouple on the top.  I will bisque tomorrow to see how it works.

I had the glaze fire on Friday, and opened the kiln today.  All looked good, except one piece.  I am very happy.  When I draw the sample at the end of firing, the clay got lots of carbon (gray),  reduced too much. I had some pieces at the front of the kiln had crawling started slightly.  I will place three test pieces at the next firing, and draw them at the different stage of the firing to see when it collecting the carbon.
