My friend who has the same kiln as mine is having problems reaching temperature. I am going to visit her next week to tweak her kiln.I thought some others here might be interested. The two 1/2 shelves are on half bricks tied together with about 5-7 inch posts for stability. Added a chimney after seeing the German and Scottish raku kilns. The burner is 1 1/2 inches away from the kiln wall to start with primary air disc barely open. By 1000 F I back it out a little more and increase the gas and air a little. The pressures is always a little below 5 psi.I was firing obvara today. three batches in 2.5 hours. I am beat and today is our anniversary. I will need (really bad) to freshen up!
I needed a small raku kiln for experiments. I made this one because I need to take a small kiln for demonstrating some techniques for a teaching video. I had a roll of 8" wide 2" thick ceramic fiber that was a gift from a former student who worked at a refractory supply in Montana. I have had it for almost 15 years.The jacket is made of 16" wide flashing. The fiber is treated with rigidizer to contain the airborne fibers. Will fire it up in the morning to seal it.
