bone china??

      This is not made of bone. The glare of the light and the purity of the white coloration can assure that. I would guess that it is porcelain (or some other sort of ceramic if not that, though it is probably pircelain) with metal around the edges and a glaze to cover it all.

      Of course, if I am mistaken and these dishes aren't smooth and cold but rather warm and almost wood-like, then you've got yourself some bone objects. But bone was only ever really used way before thay decorated things.

      That red mark in the third picture is a signature.

      Sadly, to evaluate your items, I would need a bit more than just pictures. We'll start with an easy one. How much did you pay for it?
