Dear Tony,=20

This sounds like a good idea <<<

How about glazing the bricks with my old 70's Oatmeal glaze

Whiting 300

dolomite 1050

talc 1050

felspar 2025

Nep syn 1275

EPK 1500

Flint 300

Zircopax 750>>>>

But I think it would be important to give it an initial firing well =
above the intended salt glazing temperature to ensure that all of the =
silica and felspar had been taken into solution. As I suggested in =
another posting on the topic, Potash felspar reacts strongly with NaCl =
and free Silica with Na2CO3. Interesting to see that you would have =
Zirconium in this glaze!!

I can understand that, put on the underside of shelving, there would be =
little response to salting. Gravity at work here.

All the best,

Ivor Lewis
