Bought two small bottles of shellac a few weeks ago. I havent even opened them yet but I can see that a white clumpy substance has formed in both bottles. It goes away if I shake it, but is this ok or should I return them as I haven’t opened them yet? Its Liberon sealer so its good stuff. Is this possibly a bad or old batch?
Sounds like there might been moister in the container. I would return it to the store where you got it. You might be better of with flakes, that way you can just make a small batch when you need it. If you keep the flakes in a sealed container in a dry dark place they will last for a long time.
