Hello Robert,
If you are using Zinser's shellac check the bottom of the can for
the date that it was created on. Shellac only has a shelf life of 6 to 12
months.

I am having this same problem.i just checked the bottom and then the entire surface of both my Zinser cans. no date in sight???? I bought them both at Home Depot???

18 years later Zinser may be placing the date code somewhere else.

Not recalling the thread in 2000, but, seems to me you can buy shellac
in chunks, chop it up and dissolve it in some pure booze. I see no
reason a can of Zinser's would go bad, or have a shelf life at all. I
have used cans several years old and works just like new cans. Perhaps
that's why no date on your can? If you have a 20 year old can that
dry's up, chop it up in your wife's coffee grinder and soak it in
alcohol for a while.

Have had Zinser's change from clear to a gray opaque, and when I
opened the can the lid flew hit the ceiling when it blew off. The can
had been used in the winter and sealed, open at 90 f in the summer.

Not Zinser's. It has conditioners and hardeners in it. Once it has completely dried, it won't resolvate properly.

Are you saying that you are having the original problem as the original poster, that your coats of shellac won't dry?

That makes sense. Never had a can completely evaporate on me though.
Never had a can "noticeably" evaporate on me that I recall. I try to
keep a can of Zinser's on hand at all times, and about the longest I've
stored it is a few years, never had a problem with evaporation or
application though.

I suspect he's looking for the date written as plain as pie, not coded. Zinsser still uses the coded dating system. If my suspicions are correct, he needs to learn the coding system.

As to shellac in flakes or chunks, as Jack mentions, store the flakes/chunks in a cool place, like in the frig.
