68 How long can you store hide glue?
Dry glue has an indefinite shelf life if stored in a cool, dry place.
Mixed glue can keep in the refrigerator for several weeks. Liquid
glue (with urea) is good for several months, longer if
refrigerated. Keep the lid tightly capped. Mixed glue can be frozen
to last a very long time. Remember, glue is a gelatin and should be
treated like a food, it can spoil and "go bad" if left out. It is used
as pill capsules and marshmallows. (Don't forget "Jell-O")
Once the glue is dried, as in a joint, it will last "forever", but
bear in mind that hide glue hydroscopic and will react to the relative
humidity. If the RH dips too low (10% and lower), for an extended
period of time, the moisture content of the glue joint will lower
making the glue brittle.
