Dear Readers:

I am looking at a glaze formula that calls for a Hommel Frit # 494 and
wonder if there is another frit that I can substitute with? pemco etc.

I would like to fire this cone 8 glaze- (test tile) in a cone 9 firing and
well, lets see?

Hommel Frit # 494 18.7 (sub? equivalent / grams?)
Lith Carb 5.3
zinc oxide 23.1
Custer Fieldspar 13.2
Kaolin 8.6
Titanium Dioxide 2.7
Silica 22.7
whiting 4.4
Bentonite 1.0

Thanks to all
