If you heat and melt some emulsion (say 40C or higher) do not save it in the bottle with the main bulk of your emulsion. If you must save it, save it in another container. Heating emulsion until it melts changes it.
Having liquified emulsion is abnormal. It should be stored in a refrigerator, and when you do that, the gelatin should become stiff. I cut mine with a knife and dish the solid out with a spoon. At work, we used such large amounts that we used rubber gloves to grab a big chunk and then we weighed out what we needed. We had space in a walk in cold store for the huge mass of emulsion, stored in 10L or larger cans.
