Photo-lithophane is not practiced today as far as I know, it has been
substituted by photopolymer plates and some other rubber-casting techniques.
The idea is the same as before, only gelatin is substituted by plastic,
rubber or resin. Porcelain casting forms are prepared from the molds, that
have recieved a decoration made by a photographic relief on a thin layer of
latex or rubber.
In addition there are some computer programmed machines, that are able to
make any type of molds by carving, also after a photograph.

Galina.

Christine, that sounds like something called -- as I recall "lithopone."
I have a photograph of some in a file which I might one day locate, and
once found a description of how it's done -- possibly casting fine
porcelain over a raised gelatin photo relief. It is EXTREMELY beautiful,
but the process was not simple.
There used to be a magazine called Ceramic Monthly. If it still exists, it
might have such info. Sorry I don't know, or can't remember, more, but
.... maybe Galina?
