The plate dried out quite quickly in my basement - about two days - as I never store them in the fridge.
I'll try to get a video clip posted to You Tube, later today, of me working with the natural dyes and the gelatin plate. It all depends on if I can get the video to cooperate, it's been a couple of months since I've worked with any of this and am starting to get a bit rusty (Oh I'm doing some rust dyeing on my day off) at video editing.
