Carpenter's White Glue Print

[sanking]

"I just read a description of a vintage photographic print for sale. "Carpenter's White Glue Print." That's a new one on me! I believe the print is from the 40's. Anyone ever heard of a "glue print?" :confused: "



Gene, for some reason I could not reply to your thread so I started another thread with the same name.

The only thing that comes to mind is that white glue has sometimes been recommended as a substitute for gum arabic in the gum bichromate, or direct carbon process. I played around with this myself many years ago, using plain white glue. This stuff is not waterproof, which I guess is what lets it work like other colloids.

I am not an avid gummist but in following discussions on the subject I have noticed that folks are using a wide variety of substances (polyvinyl, gloy, white glue, tempera, etc.) other than pure gum arabic in processes which they continue to call gum.

If you check on the silkscreen supply houses you can find the diazo photoemulsion for silkscreens. Ulano is one such brand. When I worked with it years ago the diazo and colorant was added separately so you can replace the color with your own. With an intense enough color you can get continuous tones by spreading the emulsion thinner on paper than you would with a screen mesh. It'll take some trial and error to get it right.
