Multiple Polaroid Emulsion Lifts on Glass

[honeyblob]

Hi everyone. I hope this is in the right category. I've been playing with polaroid transparencies and emulsion lifts lately, and am curious to try an emulsion lift on glass or a mirror. I was thinking of covering the surface with multiple emulsions, but here's my question. If I do an emulsion lift on glass, and the emulsion dries, will it become malleable/will it come off if I put it back into water to put another emulsion lift onto the same piece of glass? Has anyone on here tried doing something like that before? It would be difficult to manage two wet emulsions at the same time.

Thanks very much!
