Leslie Ceramics is a nice local ceramics supply place. The staff are knowledgable about most things ceramic... differences in clay bodies, glaze material substitutions, etc. Their selection of tools is pretty good. For run of the mill stuff (sponges, basic tools), you'll probably get it cheaper at a more generic art supply place. They're great if you need a pound of some glaze material and don't want to wait and order it from someplace on the net. I used to thing their prices were higher than ClayPeople up in Richmond, but I've done some more extensive price comparisons, and they're actually less for most things. Kiln hardware seems to be cheaper at ClayPeople, but glaze materials average less at Leslie's.
