To Claylover about the red. In my experience, it is the cooling cycle and the crystallization that occurs then that brings out the red. In my studio, I run a cool down program to do this. I have noticed in some studios where the kiln is in a small room, or multiple kilns are firing, the reds come out great with out a cool down program. I am theorizing that the insulation slows the cooling down. Aside from firing conditions, Claypple is probably on to something in calibration differences.

My plenum cup is about 4" wide and 4"tall. Three 1" holes drilled at 90 degrees, 180 d, and 270 d from 2" output for the hose to the exhaust fan. Adjustable bolt holds it to the underside of the kiln floor. Wish I could draw this. Air coming out of the fan is not hot just warm. Drawing air through 2 5/16" kiln holes and 3 1" cup holes.
