Ferro Frit 3124. 44.5
Custer Feldspar . 20.0
EPK Kaolin. 5.0
Silica . 8.0
Add: Tin Oxide. 9.0 %

From Central Carolina Community College,

It flakes off the bisqued pots prior to firing.
I have wiped the pots with damp sponge as I always do, I have even bisqued higher than normal. It is an attractive glaze when the glaze actually stays on the pot even when cracked and fragile.
i dip the pots.
I get the deep toasty colour where thin and the whiter colour where thicker.
It has a high bentonite content.
Yes test, but the brilliant chemists out there, will dropping the Bentonite content help, and would one replace that with more EPK?
I've used MGSO4, glaze mix is thin but not wanting to add more water what is your advice?
