Well, I simply can't open it. Would it help to put it in a bowl with boiling water or what?

Hope someone has an idea. Thank you!
When you say you can't open it, do you mean you can't get the long metal bar OFF, or that is off and you can't get the pull tab on the rubber ring to release? I used a firm knife as a lever, and got a bit of air in slowly to help release the glass top. Just lift the knife and you see a few bubbles, hold that position and wait, release and pry it up again, let more air in.

I am clearing out my Dad's house and I found 27 jars of peach preserves and 4 jars of apples sauce in those jars. Being as they were about 30 years old I decided to open them outside and dump them in a hole I dug in the garden - instant compost! A few were really tight and the paring knife did the trick. Just did this Saturday!
