Since I had some extra Kaowool, I decided to build a new lid for my raku kiln. Believe it or not, I couldn't find one store that would sell me just the garbage can lid. So, I had to buy the whole works again. I had heard from many sources that I should put the hole in the center, so I did. I cut the hole in the lid with a pair of tin snips, painted a coat of sodium silicate on the inside of the lid, set the Kawool in place and further secured it with 1-1/2 inch squares of rigid fiber board buttons threaded with nichrome wire.
I'm not sure if this kiln fires any more efficiently with the hole in the center. I didn't notice any difference in firing times for finished product. But one thing for sure---it is a lot easier looking into the kiln with the hole off-center. My favorite addition to the new lid is the two heavy-duty handles, which makes removal much easier.
Took my first clay classes at Bemidji State University in 1989. In 2002, after a long break, I started more pottery classes at Viterbo University in La Crosse, WI.
I do not have one area of interest, but that isn't to say I am unfocused. I enjoy making everything from coffee mugs to trompe l' oeil. I work with highfire stoneware, and low fire earthenware. I'm just clay crazy.
