Paving stone in oven?
Like others here, I'm sure, I saw an episode of Alton Brown's TV show recommending a 'quarry tile' for use as a baking stone. Having checked Homebase (DIY store) I found the following:
Standard Paving stone (materials unspecified - looks like reconstituted something or other)
Sandstone Paving (I get the feeling this would be a baaad choice)
Bricks (common garden variety)
Which (if any) would be the most suitable for placing in a (domestic) oven?
