The wind stopped over the weekend, and fired the kiln on Sunday. I opened the kiln today.  Here are some new attempt.

One is the stamped directly over the green-ware, and glazed a bit differently. I like the flow of the things, but I am not sure.

This is combination of the tenmoku, the tomato red and the rutile blue.

I like it.

I really like the rutile blue and the amber combination, but I cannot find the recipe for the amber glaze I came up last year. I checked the Hyperglaze, but the software acting wired and did not save the data.  My blog entry said the chun blue.  I mixed and tested the similar glaze, but turned out the celadon.  Looking at the old batch, I remember I used the different iron oxides, the iron silicate; calcined iron and silica mixture I made.  This is not feasible for a large batch, so I need find the alternative.

I  glaze the large pieces today, and fire on Thursday.

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.
