Is water based glue useable after it freezes?
Richard Jones: Generally no. Glue is so cheap really, it’s safer to buy new rather than risk failure due to freezing of your old glue.
Michael Dresdner: Most waterbased glues are emulsions in which the solids are dispersed and suspended in water. Freezing causes the solids to drop out of suspension and coagulate into a solid, unusable mass. The exception is hide glue which can be frozen and thawed and will still work just fine.
