Every ten degrees in temp will make a big difference. That includes the
temperature it was stored in for the months before you bought it. Same with
mixed shellac; in a cold climate year-round, I've had that last nicely over 6
years, yet a friend in a warm climate is lucky to get much over 6-months.

I have been using Tite Bond II glue from a gallon bottle with no expiration
date on the bottle. I have been using this for approximately 4 years.
I used about a third of it when I purchased it and had less than a half
gallon after the one year expiration date, seems fine to me but what do I
know?
Can anyone out there explain what happens to the glue after a year other
than getting a little thicker ?

I also remember when bottled/canned beer had no expiration date.

A week ago or so someone posted something about shelf life for glue. I
was surprised to learn that the regular white and yellow PVC glue had
a shelf life of about one year...

I tought when glue was too old, either it makes a film, dries in the
bottle, change color or consistency, etc...

I purchased a bottle when I was a teenager for my first woodworking
project... That bottle got packed up in a box and remained forgotten
for around 20 years... The time I was going through my years in a
small appartment and paying all the more pressing bills...

When I bought my house and started to dig through all those forgotten
stuff, I found my bottle and put it back to use as I started
woodworking again... It's been there for almost 18 years...

Guess what? No difference from the first day I used it. Same strengh,
same open time, same consistency, etc...

Now the inevitable question: Are you kiddin' when you all say one year
shelf life max?
