The need to complete this "job" for a client has passed, I told them I
couldn't gauruntee the type of finished product they envisioned in the
amount of time alloted.
But a few of the things I had worked out:
Filling a large zip lock baggie with water and using it to hold negative
in place on non-flat surface. This has worked pretty well for me on
other similar projects. On the bowl specifically, the photoi was to be
on the inside, so I figured small negs set side by side, so that the
photo was kinda puzzle piece like.
For non flat surfaces, my experience has been that the quality of the
photo will vary considerably, so I see it as a surface treatment as
opposed to a clear photographic print.
I had hoped that there was some way to glaze and fire after the
cyanotyping... but haven't found any that keeps a good color....

Have you or anyone else here on the list tried the Strands in NYC?? They
will even keep an eye out for a book for you. I don't get to NYC oftenb
enough, but if I remember, the next time I'm there I can check with them.
