Stones

Years ago, because I wanted to be able to bake two loaves at once, I bought two “Pizza Gourmet” rectangular pizza stones, put a cheap masonry cutoff blade in my radial arm saw, and cut the ends from both of them. I ended up with a surface about the width of my stove.There are lots of other solutions if you want a large surface, unglazed floor tiles for one, but this has worked for me.(Cast-iron rock pan for steam is visible on the floor of the stove.)
