Thanks Alisa for keeping my question in mind. You just reminded me to thank
everyone for their responses about my 1 ton of A.P. Green Silica Cement.
Thank you everyone, I had some really great suggestions like getting it
tested at Alfred. I had no idea what other kinds of things they tested
there beside JH and RR's leaching tests.

Are you reading Ceramic Glazemaking? I think I have this book somewhere, I
will go try and find it. You definitely have my curiosity up.

This is a good question. And I find it very intriguing. The engineer at
A.P. Green about hit the roof when I told him I might try and make something
with it, he told me if I ruined my kiln he wasn't going to pay for it. I
suspect that it is mortar for a glass furnace. (I was really hoping to use
this stuff when I build my kiln, though I hope I don't require of ton of
mortar.)
Can someone tell me more about what kind of temperatures a glass kiln might
have? I also think this silica cement, if it is mortar, might require heat
to "cure" properly. The guy who gave it to me tried to pour a patio and it
cracked badly. Can you believe he had MORE than 1 ton of this stuff?

I would be willing to GIVE someone some of this stuff, if they would like to
try it. You can come pick up or I will mail to you. Now this stuff I am
sure will travel well!
Sincerely,
