Kiln sitter.






My kiln sitter cup.
Fired probably 20 times now. It feels so fragile, but has a wonderful deep gloss as a result.
I suspect the glaze has become well and truly part of the clay body.

A "kiln sitter" is a piece that gets put in the empty spaces of a kiln so as to keep about the same volume (amount of pieces) as a previous firing. And/or placement in the kiln for a desired firing effect. The amount of content that soaks up the heat energy, affects the rate of temp. climb and rate of cooling. In a reduction firing the volume of pieces and placing is even more important, to aid the flow of heat, flame etc...
I just seem to use cups, I think because they are a more closed form.
