I work with a lot of glass negatives at The New York Historical Society.
For contact printing if it is a silver print the wight of the negatives is all you need.
Ido it with 4x5 5x7 and 8x10.
For enlarging I take the top glass from the carrier for 8x10 and 5x7 and place the
glass negitive over the bottom glass. For 4x5 I put a peace of glass in the enlarger than place the neg over it.
The contact as I said works fine with silver paper but you can have problems with
hand coated paper as it is not as flat.
I do not know much about cleaing as they come to me from the library archives so
that is done befroe the negatives reach the archives.

I know this is somewhat off subject but there are several photograph
conservators on the list and I surely would appreciate some advice.
I have been given several 8x10 glass negatives to make contact prints from.
These negatives date from about 1910-1920 so I'm pretty sure they are silver
gelatin negs. I have two questions:
(1) They are a little dirty. Is it safe to rewash them ? Would it make
sense to put them in a hardening bath before washing ?
(2) I am afraid to put these negs in a standard print frame. I might break
them. Any suggestions on how I might get good contact between plate and
paper while exposing ?
Any suggestions surely would help. Thanks
