Hi People
I was reading the adverts for ITC last month and they were stating that
ITC sprayed on the steel industry's tundish (holding vessels for molten
metal) and my guess was that if it worked to save these from cracking up
it might work on the saggar containers. (We have been wrapping ceramic
fiber around them to less the thermal shock and have been wearing masks
and messing with fiber with every load.)
Linda has now fired several ITC coated containers (saggars) 5 times
without any losses. This is VERY unusual as they normally crack on the
first to third firing.
I apply it by watering it down to a cream consistency and then spray it
on a dampened saggar inside and out. I use the sandblaster sprayer that
Axner sells for this purpose. Our saggar clay is Laguna 548 and it is
thrown to approx. 1/4-3/8" thickness in a planter or shallow bowl shape.
Hope this is helpful to some of our fellow and sister saggar firers out
there.

PS-The latest Claytimes has the details on saggar firing but discovered
the ITC after the article went to press.

Charlie,
You may want to try another sagger body. One of the grads at Bowling
Green State University makes saggers from fire clay, ball clay, medium grog,
and kyanite. The body is just barely throwable and will take the prints off
your fingers, but they seem to last a long time in the anagama. I'll try to
get the recipe for you.
