Have you ever gotten a stopper stuck? JohnB. posted this question on the chemistry forum:
How do you remove a ground glass stopper from a bottle with a ground glass neck? I have tried cold water (and ice) on the stopper and hot water on the neck, tapping the neck of the bottle, ammonia, holding the stopper with various types of cloths (rubber, cotton, etc.). All have failed, any suggestions?Aside from breaking the flask, what would you do?
