I dont know what type of glue your using..ie cyanoacrylate (super glue) or what the base monomer is made of. I have yet to wear but I guess soon enough I'll find out. However, I do work for a glue manufacturing company. I can tell you if your using a cyanoacrylate (super gule) type glue you should always keep the unused amount away from moisture. That not only does moisture start the polimarization (curing) it can also hasten its shelf life ,prevent the viscosity (ability of movement) from being what you want and reduce its bonding ability. Best way to prevent this is always store in cool, dry, and dark place. I dont recoment putting it in the same refrigrator you eat from but, what eles are you going to do..hey good reason to buy a beer fridge lol Other chemistries work differently, however, air is not glues friend in 95% of standard glues air changes glue (its not just the air but things in it..but you guys get my drift I'm sure) and I have more learing of what types of gules you guys use.

Hope that helps a bit.
