Na, the tea pots and that kind of ceramics are mostly alumina and silica that are fused together, and most of those are at 1700 degrees F, low fire or cone 06. A lot of the art type ceramic pieces are high fire cone 9 or 10, somewhere around 2500 F. Either are hard, but fairly brittle. I don't really know what they use in the ceramic knives, but I am sure it is not regular tea pot clay.

I have fused pieces of nickle and copper into high fire ceramic slabs while they were being glaze fired, but that is not easy to control; the metal just ends up in blobs in the ceramic.

All that being said, this thread has got me thinking about the ceramic cantles again. Perhaps metal overlays or something like that could be used on a ceramic cantle...
