Tonight, I gave a rousing talk on open source GIS to a group of students at Portland State University.
I have not doubt they will seek out the things of which I spoke! I hope you students enjoyed it, I’ve never talked for 45 minutes straight in my entire life. Feel free to leave me a comment!
Here is the presentation for your viewing pleasure (download)
The Soulgama kiln was fired up last month out at Stephen Mickey’s place. I had a great time firing with everybody and I definitely came out with a few really sweet pots.
This time we decided to try tumble stacking the back section, which is typically the coolest part of the kiln overall. We managed to keep the back (the floor at least) around cone 10 (2350 deg F) while flattening cone 13 in the back of the middle section of the kiln. There was very little fusing of pots in the tumble stack due to excessive accumulation and melting of ash. We were going to attempt to cool the back in a reduced environment (for iron rich clay bodies) while allowing the front and middle to stay in an oxidized to neutral environment (for bright porcelain and lighter stoneware bodies), but it was ultimately decided that it was not worth the risk of muddling the brightness of the clay bodies and glazes in the middle and front sections (which hold the largest amount of pots by far).
