[TheForge] flux proof forge floors ?

[Peter Fels & Phoebe Palmer]

Kinda fishing around here...The story....
An old friend died a while back, he was a potter and a packrat in the 
grand sense of the word.
A mutual friend bought the property and is cleaning it out for his own 
mess. I just returned from there with a flatbed of bedframes.
One of the stacks in the yard he wants to sell consists of 1" thick 
carbide kiln shelves, about 2'X 2'. I'd guess there are about 30 of them 
more or less. They are all mildly warped.
I've had part of one as a floor for my Sandia forge and it seems 
unchanged by the heat. I cut it with a carbide masonry disk..scoring on 
both sides, then breaking it off.
These puppies are not light and were gawdawful expensive new.
Any idea what they are worth? Any interest from you guys in some of 
them? Any suggestions?
They are in Old Edna, near San Luis Obispo in central CA...pete
