What is the importance of Plath's, The Bell Jar, in the novel, Belzhar

“The Bell Jar” is the name of the novel by Sylvia Plath that the students in Mrs. Quenell’s class read during the semester. In science, a bell jar is used to isolate a sample from the rest of the world. Plath felt as if she were trapped in this type of jar and isolated from the world around her. It is inside a symbolic “bell jar” that Jam had trapped the love that she believed Reeve had for her after she figuratively killed him.
