Yes, after losing a uro to long term lead poisoning, only then did I learn that my herp vet had already been in the midst of researching the effects of brick, cinder blocks, concrete, and pottery in reptile cages. Many (read: 'much, but not neccessarily all') of these products can produce toxic effects, that may or may not be immediately noticeable.
Uros constantly lick things and ingrediants in these items or glaze on pottery can be harmful. Please research your possible decisions before putting in their cage. Heck, I just moved in to a house with a LOAD of flagstone outside. Swing by, I'll give you a piece or two.
