Is there any source for dry glas plates? I mean glass plates coated with a dry emlusion and sensatized?

There are only three types of mounting flanges; too big, too small and wrong thread!
I saw some at an Antique shop. They were opened and exposed to light so probably worthless. Unless you mean to recoat them?
I don't know of a source for new dry plates but there is a lot of information available on making them yourself if you that appeals to you. Searches here on LFPF and also on APUG should get you information on coating glass with commercially available liquid emulsions. Denise Ross has a website called The Light Farm that has a great deal of information on making your own emulsions for papers, film, and dry plates. I am gearing up to make some 5x7 plates using information I acquired from Denise's site.

Thanks for the info on Light Farm. If i cannot find a prepared dry plate from a manufacturer, I'll have to go this rout. I really don't want to coat plates though.
I am exchanging e-mails with a company that makes plates for Laser Holography. We'll see where that leads.

Why?

Actually I would be interested in this too. I have an old Rolleiflex that has a glass plate back, and several plates. In fact film ever runs out, I want to know how to coat my own glass

I would like to avoid the mess of working with this stuff in the dark. I want a standard material that I know the properties of. Our home does not lend itself to converting any space into a photolab . . .it has been discussed in several family meetings over the years.

hey drew
you can bypass the making your own emulsion part
and buy some liquid light and easily coat glass or plastic
yourself. a cheap paint brush, a blow dryer and plates
its fast so you just need an empty film box and some wax paper to interleave them
no lab needed ...

good luck getting them premade + cheap
when kodak made tmx 4x5 plates they cost more than 400$ a box of 100,
which was more than 4x what film cost.
have fun !

The upside to factory made glass plates is situations where very exact enlargement factors are involved. High mag transmission electron mircoscopy comes to mind. I use to develop tmax 100 quarter plates for micrographs where the shrinkage of estar base material was unexceptable for the parameters.
For making pictures its hard to see an upside, unless of course you just want to do it.
