100 ? Year old Kodak glass plates !

[timofred]

I am seeking advice on exposing and developing these glass plates.
No details on the box,
emulsion ?
ISO ?
I have ID-11 dev,
might be able to get Rodinol from a friend.
Any help greatly appreciated.
Cheers, Timo.

No personal knowledge of these, but I found this page where someone experimented with some early plates:

How many do you have? Could you rig up a way to do a test series on one plate, like sliding the cover out of the holder partially in steps?

I took Photography in school but,not that long ago.
By the looks of the packaging, moisture stains and the tear below and how they were stored, sadly they may not be much good anymore but, I know nothing about plates of this type.

To even open them slightly will expose them to light damaging most of them if there are okay, they must be ONLY opened in a darkroom.
Here's a couple of places you can check out.

Great idea, thanks.

Do you know if their exposed. That looks like a sealed factory pack. It takes special skills to develop old film the same may apply to glass plate.
