From a quick look at your site, it says your double-layer of pizza stones sits directly on a layer of sand. How is this working for keeping your stones hot? Do they retain their heat for a long time?

"Harbison Walker (ANH Refractories) has 24"x12"x2.15" refractory tiles which are made of the same material as their firebricks. A year ago these were $32 each at their location in Los Angeles. They have a location in Dallas."

If this is right and the shelves are fired to the same temp as the bricks, then they should be the same density.

When I picked up my floor insulation from H-W I tried picking up one of these floor tiles. They looked exactly like the firebricks they had there except maybe a little smoother. They were proportionately heavy and my only thought was "I wish I could afford these"...

Density has nothing to do with conductivity. I'm talking about completely different materials here. Kiln shelves are generally made of Cordierite, which is much more thermally conductive then firebrick. Any I've ever seen that are Cordierite are an even more thermally conductive material.

Sure, but Gianni said Harbison Walker told him that the shelves were made of the same material as the fire bricks. My reference to density was assuming the materials were the same and therefore the only other variable would be the temp they were fired to which does affect density because the higher fired material will be denser because there is greater shrinkage.

Got ya now. I was responding to the original poster which I now see was a couple months old. Too bad this old thread was brought back to life by another shameless attempt to drive commerce to another site and away from forno bravo.

Yes, the refractory 'tiles' were made of the same material as their firebricks, but I'm unaware if they are used for kiln shelves.

Sorry, my misreading, as the tiles are over 2" thick I doubt you'd be using them for kiln shelves.

At $39 ea and a double layer, that"s a pretty expensive floor.
Doubt whether you'll be selling too many of those.
