The cylinder is about 12" in diameter and I have cut 8" holes
in each end. I would like to line the cylinder with 2" of
Kaowool, painted with ITC-100 and then put in an 8" wide section
of 1" thick kiln shelf. The shelf will stick out each end a bit.
Seattle Pottery Supply has 1" thick cerablanket in 4, 6, or 8
pounds per square foot. Which density is best for my application?
The Anvilfire store sells the 6 lb stuff so that would be my
default unless there is a compelling reason to go lighter
or heavier. Any one care to chime in on which weight would be best?
Also, there are a variety of kiln shelf materials available.
I'm looking for something that is durable and can withstand being
blasted by a 3/4" T-Rex burner. Mullite, silicon carbide, and
high alumina shelves are available. I have found references that
high alumina would probably be suitable and that mullite would not
be as good. Not sure about SiC. Can some one enlighten me as to
the properties of each material?
Thanks for helping a neophyte out--I'll probably have more questions
as this project progresses.
