This was a real find from a very old local school that was closing. This old item was m. Ade from very heavy glass. Complete with Glass Stopper. Perfect for isolating experiments from outside interference. This Bell jar is for use in only Physics Experiments to teach Science. It should be able to withstand amounts of vacuum by common mechanical pumps. Any imperfections found in the bottom of the Bell Jar are air bubbles that occur during the firing of the bell. Every Bell Jar has this to some degree. It is not a damage or a crack. When I inspected this item closely, I noted only one small air bubble. This imperfection should not affect the performance or integrity of these Bell Jars. I would trust this item to withstand and possible vacuum. I just need to liquidate some of my prized vintage pieces of glassware. Please help me liquidate some of my well loved treasures.
