Kodak makes a number of glass plate materials for special purposes. From
"Search" type in "plate" this will bring up a list of most of them. The
specific URL for Technical Pan Plates is:
http://www.kodak.com/global/en/professional/support/techPubs/ti2438/ti2438.s
html
Most browsers will truncate this when you attempt to paste it in so its
best to do the search. Kodak also puts up T-Max 100 on glass.
The plates are quite expensive.
Two suggestions:
1, Make film adaptors for your holders using a sheet of glass or plastic
(or metal) the right size with photo corners on it to hold standard size
sheet film. You can also stick the film on with double stick tape or just
tape it at the corners. Mark the ground glass for the actual image size.
2, Make your own plates using one of the liquid emulsions on the market.
You can use plastic instead of glass. If you use glass or plastic it should
be about 1/8" thick, check the holder to see what it wants.
You will probably have to coat the glass with a substrate of cellulose
nitrate to get the emulsion to stick. Very hard gelatin may also work.
There is an abundance of material in the literature on coating. Probably
one of the groups which use wet plate process will have recommendation. The
emulsion may stick without anything if the glass is really clean. The
emulsion manufacturer may also have suggestions.
Kodak coats plates on acrylic plastic so it must be suitable.
