I got hold of a few boxes of Ilford Glass Dry Plates in very good condition, they have no expire date but according to the Early Photography website it dates back 1950's.
I've run a test to find out how sensitive the plates still were after all this years and I had a good result at 20 seconds f/4.6 in sunlight.
They came out slightly over exposured, the sun was probably stronger in the Park but it was not difficult to adjust the levels in Photoshop. Considering I didn't have much image recorded on the first test plate I'm quite pleased with the final results.
I've used my Combi Plan tank to process and because the plates are smaller than the 4x5 sheet film, I could use 600ml of chemicals instead the usual full tank. I used a solution of 1:50 Rodinal / 15 minutes normal agitation.
The shots were taken using my Voigtlander Avus plate camera.
