What is the best way to unstick a glass perfume stopper from a glass bottle- it has dried perfume between?

You could try placing the bottle in hot water in your sink, let it sit for a little bit then try and remove.What is the best way to unstick a glass perfume stopper from a glass bottle- it has dried perfume between?
I disagree with all of them. Try putting the bottle in the freezer for a while. Things contract when cold, all you need is a little schrinkage and your back in business. good luck.What is the best way to unstick a glass perfume stopper from a glass bottle- it has dried perfume between?

I agree with the hot water but if that does not work--try putting the bottom only in hot water--hot should expant the bottom a little.
Try taking a rubber band and putting it around the stopper until it is all used.That will give you enough to hold onto while you try and turn it. If you want use a hot cloth and clean all around the stopper first.
I agree - hot water has worked for me in the past.
