And now my reply to move this to the forum....
Thanks, PE. I'm going to move this to the forum and then reply when I figure something out. Right now I am just doing some trial and error with the 10% gelatin only mixture (no silver). Coating temperature of the substrate seems to have a lot to do with it because the warmer base coats better. Unfortunately, that isn't the whole problem because that will strip, too, if heated. Adding the hardener has also changed things because with hardener it seems to be harder to strip. (10% chrome alum added about .5 ml to 10 ml of 10% gelatin)
I'll also see about dipping some of the stripped emulsion into warm water.
