Liner and IR coating
I have my 20 pound propane tank prepared, my T burner built and the ceramic blanket and digitizer are on the way from Front Porch Forge in Edmonton, AB. I'm going to make the liner using 95% Zircopax and 5% Vee Gum T and use the same ingredients to cast the NARB. Can I use Alumina Oxide and Vee Gum for a brush on IR coating or should I stick with a thinner mix of zircopax or order Plistex from Wayne Coe? I can get these ingredients in 1/4 pound or 1 pound bags from Greenbarn Potters Supply in Surry, BC and I'm wondering how much to order for a forge this size.
