ORWO glass plates

Hi all
this is a double post from I Shoot Film, just to widen petential glass plates users

Recently i got a lot of unused orwa glass plates, 3 different one.
Do you still use them? do you have some info about em?

Interesting. I shoot 4x5 and 5x7 plates, and have to coat the glass myself. Would be interesting to run some through if they were that size but it looks like they're 6.5 X 9 cm (~2 1/2 X 3 1/2)

The NP20 plates will be similar to the Orwo NP20 roll or 35mm film for conventional photography. The others are special emulsions for scientific research, EU2 for electron microscopy and WP1 for spectroscopy (astronomical).
With this, and noting the expiry dates of around 50 years ago, they are perhaps more interesting as collectables rather than for practical use?

Thank you guys

You could make a simple pinhole camera for this size of glass plates and test it.

i might better ending selling it all... i have less time now with two little kids

I have used a lot of Agfa Scientia 6.5 x 9cm glass negs, in a vintage Voigtlander plate camera. The plates expired around 1984. I've had some good results, some plates were very clean, others quite fogged. I also had some Ilford HP3 plates that were so fogged they processed as black even without any camera exposure. It's an interesting thing to try if you have the right equipment and are in the mood to experiment.
