Hi there, fellow toe dipper! Makes sense. But is that swelled gelatin or dry? I am guessing swelled since each formula tells you to swell the gelatin first.
Well, last night's experiment has now produced a piece of film base with a fairly uniform green tint to it since I did put green food coloring in the gelatin. It feels like a piece of film albeit a little on the thin side. The gelatin coating is hard, clear and shiny and does not seem to want to come off the base. Therefore, I will consider this a success.
Also, remember to take the film OFF of the glass after the gelatin has set up. Otherwise it glues your base to the glass!
