you could also leave the plates out in the sun with "stuff" on them
i like yard waste, leaves, chains, negatives, plastic ... if it can blow away in the wind
put a piece of glass or saran ( weighted down ) on it ... and make some
cameraless, sunprints.

i've been doing that with glass plates and it is a ton of fun ...
but your actual mileage may vary from the mileage at the factory ...
