ALPS makes a special plastic material which takes the image in reverse,
which can then be transferred to any medium (including ceramics, I would
imagine). Someone might like to experiment to see how much heat the
transferred image will take during firing. The pigment is in a plastic
base, and the plastic certainly would fire off. Be worthwhile
experimenting; I can't do it as I'm not into ceramics, but I'd be willing
to work with someone in return for agreement to publish an article for the
PSA Journal, if successful.
