Albumen can be used on glass. Actually one of my latest obsessions. Can be used as a negative on glass to make contact prints (one of the methods of reproducing images at the inception of photography) and as a positive (heliographs) and also in white milk glass, called opalotypes.
I did some research and found the personal notation for a conservancy program being taught by Mark Osterman on this issue. He was surprised since the course in question never took place and he was unaware that the notes had been placed online. Glad they were. I now have about 30 books of the 1800's on this matter that I am drawing from to make opalotypes.
Btw, one can also use collodio-chloride to make opalotypes (same chemistry used for POP - Print Out Process). All exciting and somewhat obscure nowadays simply because of our never ending interest in dumbing down photography. It is ready stunning to read from original sources of the 1800's and find that most photographers were scientists and common to have written books on scientific matters other than photography. We lost all that rounding and renaissance knowledge capabilities. There are hundreds of formulas on the account of how proficient and knowledgeable these folks were with chemistry.
Collodion exists in negative and positive. Negative being in glass, ambrotypes (once painted the back it becomes a positive) and positive as I just posted in tintypes (can be in tin, aluminum...etc) . They can be tinted and burnished whether in glass or tin in a variety of colors and can be in dry glass (called dry collodion as in opposition to wet plates) for ease of transportation and can be also wet preserved process for ease of transportation as well (called the Oxymel process). Truly fascinating methods for making images.
PS. Kodak now in bankruptcy but claims that film remains profitable. They just have to get rid of their digital printing products once and for all.
If you are interested in learning more or wish to take a workshop, I would suggest to learn from the best. Here: http://www.eastmanhouse.org/events/series/photo-workshops
Btw, you have someone in NZ that is an expert on alternative processes. In fact, just last month I purchased a passe partout for a daguerreotype from him. He did a bang up job on it. His name is Alan Bekhuis and I know that he is making cases for daguerreotypes made by Daguerre himself. Here: http://www.casedimage.com/
