The reasons suggested in letters posted in this week's Bread Digest are correct.
There can be unpleasant elements in the glaze. And also, the non-porous
nature of these tiles defeats the purpose. Try a large, warehouse-type hardware
store such as HQ to buy them or a tile-only store like Color Tile. I see them in
these stores. Also, yesterday I saw a lovely, large rectangular baking stone in
my local Target store for juft $16.
