One of our ceramics instructors wants to try placing photo images on clay.
She has been doing some research and has passed on to me an article which gives some basic information.
We will be helping her in the darkroom part of the process, and am looking of any tips that may be helpful from anyone who has been using this process.
Based on the article i am reading, it seems as if one of the Rockland products would be a good emulsion to use. Anyone out there using this process, or have tried it out for themselves?

I've been considering this because my brother just got a kiln and we've seen fired photographic images. I'm thinking any process that uses a gelation emulsion would be incompatible. It would most likely be a process like salted print or platinum palladium coated directly on the bisque, exposed and processed, then fired under a clear glaze. I think an unglazed tile would be a good place to start. We will probably try this out before too long. I'll be interested to see what you can find out in your efforts
I don't know about Rockland products, but if you want to get good image quality, you must pay attention to provide good smooth surface on which the emulsion is coated. How you can do this depends on the surface of the ceramic, glazed or otherwise.

Also, don't forget to harden the emulsion itself as well.
Hope this helps.
thanks to everyone, this is going to be an interesting experience.
When i agreed to assist in the darkroom end of things i thought the instructor had a better handle on the process. SHe is a great person and makes real fun stuff, but is a bit in lala land about the process.
And of course, i know nothing about clay, except you have to throw it around to get the air out. Am sure it has a technical name, but don't remember it from college when i did take one class.:rolleyes:

Generally images for ceramics are either silkscreened or applied using a process much like carbon printing.
Commercially other processes are used as neither of the above processes are fast enough for mass production work.
Somewhere out there is a really good site covering the traditional process. Once upon a time I had it bookmarked but can't seem to find it now..
Alternative Photographic Processes, Webb & Reed, ISBN 1-883403-70-7 mention that gum printing can be used on unglazed tiles. Watercolour pigment is substituted with underglaze pigment, the tile coated, exposed, washed and dried. Coat with transparent glaze and fire.
Hope that helps,
