A lot of cermic material slated for construction use is not food safe,
typically those tiles you speak of contian heavy metals like lead and
cadmium.... I'd strongly urge anyone using any ceramics in their
kitchen to buy a test kit and use it (they are available).... wasn't
too long ago a poster here bought a ceramic tagine, when advised to
have it tested it was found to contain lead.
