Dear Nils, Pete, Vince and Mel
Since you guys have access to people that will test stuff for you, try this
on for size. If the whole point of this softie, salt thing is to
encapsulate the soft brick why not glaze the frigger with a high alumina
matte glaze. this would be a hellava lot cheaper than ITC, the salt would
not penetrate the glaze and as a side benefit the inside of the kiln would
be drop dead gorgeous.
How about glazing the bricks with my old 70's Oatmeal glaze
Whiting 300
dolomite 1050
talc 1050
feldspar 2025
Nep syn 1275
EPK 1500
Flint 300
Zircopax 750
When ever I heard glaze nerds trying to guess what was in ITC they always
seemed to point to zirconium. So why not use my glaze and save the big
bucks.
I painted the underneath of my high alumina kiln shelves with this glaze and
wood salted them for 15 years. they stood the test of time.
I'd love to hear if the dunkin donut approach worked.
cheers,
tony
P.S I know Craig has testies too, but he has to get ready for santa and
can't afford to miss a drum beat in his next firings.
