Hello all! Few weeks ago I started my adventure with hand-made gelatin emulsion for glass plates. I found Mark Osterman recipe and guide. I followed it as firmly as I could but of course there were some small differences (mostly caused by lack of specific equipement, I also use food grade gelatin, not photographic grade - it's not easily accessible here sadly). The results are somehow not satisfying and I cannot eliminate the problem that I'm having which is lifting off of the emulsion. 80 % of the plated I made has lifted off, it doesn't happen always the same way - sometimes it looks like the emulsion isnt "glued" to the surface if the plate at all and it just go off under water. Some other times it looks like the surface of the emulsion itself is melting and it's not smooth anymore, it has a wrinkled texture. There were also times that in the middle of the plate under the emulsion some kind of bubbles appeared and the emulsion started to lift from this spots on. Finally on a few plates the emulsion shrinked and after forming a web of ruptures also left off. All those effects are happening on the same moment - after developping while washing and before fixing. I tried several theories I came up with why it is happening. I ruled out bad developer, too hot temperature, bad water for washing (I tried with running and destilled water), different thickness of the emulsion, different methods of cooling emulsion after coating, lack of chrome alum (I made a 2% alum bath before and after developping). Nothing worked. Then I found this forum and I thought maybe I'll try to ask for some advice here because now I'm seriously clueless. I hope you guys will help me out. Thanks in advance (and sorry about not-so-good english), Asarnil.
