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.
