New Raku Kiln Lid

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.
