Chosen Solution
I have an antique perfume bottle with a glass stopper on top. A part of the stopper broke off. How can I get the broken plug out?
Diane Keating clean the visible part of the plug with some sand paper. Then get yourself some silicone rubber adhesive and glue something like a screw with the head first onto the plug. Let it sit for 24hours. After that invert the bottle whack the bottom of it with your hand a couple of times and try to pull it out by the adhered screw.
