I have another question. I was in the darkroom today and noticed that one of my two bottles of AJ-12, one that hasn't been warmed up at all since it was made around 11/15 had turned to liquid at room temperature. It wasn't a gel anymore. I put it in the fridge before I left, but I'm assuming that this is a sign that the gelatin has broken down and that the emulsion is a goner. Does anyone know if that's a correct assumption?

Also - if AJ-12 doesn't hold up at room temp for more than a few weeks, instead of making batches of emulsion every couple of weeks, are there any basic chemistry changes/additives that I can make that could help lengthen it's shelf life? Would using photo grade gelatin help at all?

Any input is greatly appreciated as always!
