“Scientific instruments have become quite collectible. A vintage barometer, for example, can look distinctive in a home and serve a useful purpose.
…Most barometers use a graduated glass tube that contains a column of mercury. An aneroid barometer has no mercury but measures pressure with a needle connected to the top of a metal box in which a partial vacuum is maintained.”
Editor’s Note: We had a previous post on how the ban on the selling of items with mercury in them would affect this particular collectibles market.
