Crucible
noun /ˈkruː.sɪ.bəl/ — A situation of severe trial that produces transformation; a melting vessel.
Definition
A ceramic container for melting metals at extremely high temperatures. Metaphorically: a situation of severe trial or difficulty from which something new and transformed emerges. The crucible is the place where things are tested to their limit — and changed by what they survive.
Beyond the definition
The crucible burns away everything that isn't essential. What comes out is either broken or revealed. The crucible is not kind. But what survives it is real in a way that comfort never produces.
Origin & history
Latin: 'crucibulum' (night lamp, earthen pot). Related, perhaps, to 'crux' (cross — the source of heat beneath an earthen pot). Arthur Miller's play 'The Crucible' used the Salem witch trials as a crucible metaphor.
