The glue stays in the little cups, which are about half full, so a quick trip in the microwave is all it takes to heat one up. Floating in a cup of boiling water, it stays hot until I use it.
Freshness depends on how long they're in the bag because they can dry out slowly and require a bit more water. Hide glue is food, so mold can grow in a few weeks, more or less depending on production batch.
I've had some older hide glue of unknown manufacture that has lasted well over a year in the fridge without molding (may have had preservative added I suppose) while my best clear stuff from Milligan gets moldy in just a few weeks.
I don't freeze, just because I don't need to keep it for so long in the gel state, and because there's never room in the freezer.
