For those potters out there considering it after reading the email by Ceramic Arts Daily, converting an electric kiln - I tried it 2 summers ago based on Bowers publication in Ceramics Monthly, and in my experience it was a failure, of course your mileage may vary. I'd try it again perhaps but definitely with lower maturing glazes, perhaps on a low-fire clay body around cone 03-cone 1, might get some good action.
My friend Josh blogged about our experience here: http://joshgrenier.blogspot.com - - Go to 2007 and page down until you find it. If you can't, contact me. That's me to the left after stoking in a bit of soda-drenched wood, nice haircut, heh?
All work in my Etsy store qualifies for 5 buck shipping. New work coming soon. After the fire inspection passed earlier in this week, which was a relief, I've been back at the wheel making mugs and vases. Firing in mid-stoneware range with a red earthenware clay, excellent durability for the clay I'm using. Look out world!
