I did further tests using honey on 11x14 Ambrotypes. Mixed a 2 part honey to 1 part water solution. Let the first plate sit for 1 day before washing, the second sit around 1 week. No issues with either plate post 2 hour wash.
I think I got something good here! This should revolutionize my remote shooting in the trailer. Now I can depart a location much sooner and wash the plates at my leisure when I have time and a good supply of water.
Note * I am finding/making more and more storage trays, that I can use to place the honey covered plates in before they are washed.
Things are looking good!
