Morphology

bell + jar

The meaning is directly compositional: a 'bell jar' is simply a jar (container/cover) that is bell-shaped, so a learner who knows 'bell' and 'jar' can infer a bell-shaped glass cover. This noun–noun construction follows a common, cross-linguistic naming pattern (modifier + object), making the sense immediately predictable to a B1 learner.

Etymology

Bell jar comes from its shape: a glass cover that looks like an upside-down bell and acts like a jar placed over an object. Because it is put over things to keep them safe or to hold gases, it means 'a glass cover used to protect or contain something'.
