BELL JAR Meaning and
Definition
-
A bell jar refers to a type of glass container that is typically used in laboratories for various scientific experiments and observations. It consists of a cylindrical base with a pronounced dome-shaped top, resembling the shape of a bell. The jar is made entirely of glass, offering a clear and transparent view of the contents enclosed within.
The bell jar is commonly utilized in scientific research to create a controlled and isolated environment for specimens or objects. By placing the intended subject within the jar and lowering it over a solid base, a sealed space is created that shields the object from external factors such as dust, air, or contaminants. This isolation is particularly vital when conducting experiments that require maintaining specific atmospheric conditions or preventing interference from outside elements.
The usage of a bell jar can involve various applications, including vacuum experiments, growing plants in a controlled environment, preserving fragile objects, or conducting chemical reactions under specific conditions. The airtight seal created by the bell jar offers protection while allowing researchers to closely examine and monitor the subject, making it an essential tool in scientific investigations.
Beyond its scientific context, the term "bell jar" has also been adopted metaphorically to describe a state of mental isolation or emotional detachment experienced by an individual. This metaphorical usage emerged from the semi-autobiographical novel "The Bell Jar" by Sylvia Plath, in which the protagonist undergoes a mental breakdown and feels trapped and cut off from the rest of the world, as if encased in an impenetrable bell jar.

Etymology of BELL JAR
The word "bell jar" derives from combining two separate words: "bell" and "jar".
1. Bell: The word "bell" traces back to the Old English word "belle", which meant a "bell-shaped vessel". It originated from the Proto-Germanic word "bellǭ" or "bellô". The etymology of "bell" can be further traced back to the Proto-Indo-European root "*bhel-", meaning "to sound, roar", which is also the source of words like "bellow" and "bawl".
2. Jar: The word "jar" comes from the Old French word "jarre", which was initially derived from the Arabic word "jarrah", meaning an "earthenware vessel" or "pot". The Old French word "jarre" evolved to "jarre" in Middle English and later became "jar" as we know it today.
