As most of my friends know, last years' flood took out my raku kiln. Here is a description of how I built raku kiln number 3.
I was too poor and cheap to buy a new galvanized garbage can so I used one that had been previously used as a post-firing reduction chamber.
I had just recently purchased 50 square feet of kaowool fiber from E-Bay. I thought it was a steal at 120 dollars, that included shipping. It was 1-inch thick, 8 lb. density, and 24-inches by 25-feet long.
I also found a box of homemade ceramic buttons that I made over a year ago and a package of high temp wire. Its amazing what you can find when you clean up the studio,
(It was Spring Cleaning Time). I'll get to the buttons a bit later. Ok, on to the construction description.
As you can see in this photo I traced a 5-inch circle on the bottom of this can. Then I drilled a starter hole on the line and used some tin shears to cut out the hole for the burner port. Once the hole was cut out I used a metal file and filed off any of the sharp burrs left behind from the shears. I also did the same proceedure on the garbage can lid for the exit flue.
Next I rolled out some of the fiber and traced the bottom of the garbage can on the fiber with a black magic marker. Then I cut the circle out with razor-blade type box cutter. I cut two of these circles and placed both of them, one on top of the other, into the bottom of the can. The reason for two is because with two inches of fiber on the bottom, only one piece of fiber, 24-inches tall, is needed to line the kiln. It is a perfect fit.
