I'm pouring 12=22 floor tiles from =5E6 stoneware slip that I made in my =
cement
mixer. I have some basic questions. Haven't fired yet--just drying them =
now.
1- I want to airbrush them with underglazes after bisquing, so what cone =
should
they be bisqued to in order to remain fairly porous but still be fairly =
sturdy?
2- Because they're quite fragile (3/8=22 thick) I've been turning them out =
of my
home-made mold directly onto the kiln shelves to dry in order to avoid
additional handling. Is it possible to bisque them on edge, or would they =
sag?
3- I'd really like to have a tile setter made for them, but I'm not sure =
what
exactly happens to the bisqued clay at =5E6. Would bisqued tiles of that =
size
sag in a tile setter at that temp?
TIA

Most people bisque to cone 08 to cone 04.

Yes, in fact, it's a really good idea to bisque them on edge.

They may or may not, depending on their thickness, how well they're
supported in the setter, their size, and how close to the maturing
temperature of the clay cone 6 is. Only one way to find out- fire a
few.
