Lumen Prints

I bought two carrier bags full of very old (at a guess 1960s) photo paper (and some other goodies) at Tynemouth flea market this weekend (Jan 22/23 2011) and since I needed to look at a sheet from each box to see if it had been exposed, I decided to make some Lumen prints. Some are plants, some are prints from film negatives.
The recipe I used for this was:
0) Get your paper out of the packet without exposing any of the rest of the paper. Use a dark bag/darkroom.
Everything else in daylight:
1) Put whatever you're using to make your photogram on top of the paper.
2) Put glass on top of that, if you can
3) Leave in sunlight until the paper gets dark (I used about 45 mins, but should probably have waited longer).
4) Fix in rapid fixer (this significantly lightens the image).
5) Wash in running water, then dry.

Here are more results:
All so far are done on old Kodak paper, which is no longer produced.
