I'd give these serious consideration (near the bottom):
Not as cheap as bricks. The deck of my WFO is built with these things. They have stood up to heavy residential use in pretty extreme temp conditions.
Thanks for the links about the oven floor tiles.
I didn't know about them. I am studying about WFO's and maybe by next summer, might try to build one. Could be a possibility.
I have never even tried a pizza in a WFO and would really like to experiment with one.
Your help is appreciated,
I got the tan ones. Not sure if there's a difference in heat transfer or retention between the colors. Also, I don't use them in the home oven. I've only used on the LBE (which I use exclusively for my pizzas now - No more indoor oven), but they're the base for my 19" kiln shelf, and not the cooking surface.
I used unglazed quarry tiles on the indoor oven when I made pizza in it. Got them at Lowe's many years ago.
I wish I had a LBE to experiment with.
Right now it is just my old home oven or next to the BBQ grill.
Thanks for your help and your experiences with firebricks and unglazed quarry tiles,
