I never thought it would be so hard to find a stinkin tile.
I checked at 4 places this week for any unglazed tile that is at least half an inch thick. Found absolutely nothing. I did see the Saltillo tiles, but they were all sealed with some kind of chemical. I Ended up getting some 1/4 inch "earth guaged slate" from Home Depot. Stupid thing is popping on the sides and peeling apart. Looked like it was a complete stone when I bought it, but now its apparent that there are layers and it must have been glued together or something.
I've run out of ideas and don't know where to get one of these things.
BTW The pizza I made was from the pizza inn recipe on this site. I loved it, thanks for sharing.
