Hello all,
I have a puzzle and I am curious what this knowledgeable community might have to say about it. I am hoping to combine my photography and ceramics work in the following way: I would like to coat a bisqued (that is, fired once but unglazed) ceramic surface with something photosensitive and then register an image directly into that surface. It is important (at least to keep the puzzle interesting) that there be no intermediary negatives (no contact printing)--I want the ceramic itself to be the substrate on which the image, projected through a large lens, is recorded. The ceramic would then be fired. This is also e
So here is the puzzle. Ignoring the construction of such a camera, what sort of photosensitive chemicals can I use that can both survive a firing, preserving the image to be clear glazed over later, and are also fast enough that the exposure can be less than, say, 3-4 hours. The two processes that I've seen adapted to ceramic before are gum bichromate and cyanotype--both of which are contact speed as far as I know. I had thought about using something like Liquid Light, but I worry the silver wouldn't survive the firing or else would run and blur or flake as the gelatin binder melts. The ideal process would deposit a pigment directly on the surface to avoid this.
My best idea was to use some kind of hypersensitive cyanotype, since that would at least deposit iron directly on the surface, which I know will survive the firing though it might be faint. Another idea I had was somehow using very sensitive gum process to leave a negative in unpigmented gum and then printing with pigmented linseed oil in the positive. I bet there is a better answer out there. Something fast enough, leaves pigment or iron or something directly on the surface, and can survive firing to a decently high temperature. Anyone of you wise alchemists have any clues for me? Anything would help!
