I know, I am being a pest.

I just picked up some unglazed quarry tiles at Lowes. 8"x8"x1/2"....Does
anybody have any experience using them or a link that may be helpful? I am
wondering things like do I need a space for air circulation between the
walls, do I bake directly on them or use parchment, do they need to be
seasoned, can I leave them in place all the time, ....

Thanks, Hutchndi
