==Origin==
[http://nordan.daynal.org/wiki/index.php?title=English#ca._1100-1500_.09THE_MIDDLE_ENGLISH_PERIOD Middle English] ''congelen'', from Middle French ''congeler'', from [[Latin]] ''congelare'', from ''com''- + ''gelare'' to freeze
*[http://en.wikipedia.org/wiki/14th_century 14th Century]
==Definitions==
*1: to [[change]] from a [[fluid]] to a [[solid]] state by or as if by cold
*2: to make viscid or curdled : coagulate
*3: to make rigid, fixed, or immobile
==Description==
'''Congelation''' is the [[process]] by which something congeals, or thickens. This increase in [http://en.wikipedia.org/wiki/Viscosity viscosity] can be achieved through a reduction in [[temperature]] or through [[chemical reaction]]s. Sometimes the increase in viscosity is great enough to [[crystallize]] or solidify the substance in question.
In [[alchemy]], congelation is one of the 12 vital processes for transformation to occur.
