What is Sol (colloid)?
A '''sol''' is a [[colloid]]al [[suspension (chemistry)|suspension]] of very small [[solid]] particles in a continuous [[liquid]] medium. They can be quite stable; examples include [[blood]], [[pigment]]ed [[ink]], and [[paint]]. Sols can change into [[viscosity]] quickly if they are [[thixotropic]]. Examples include [[quicksand]]s and paint, both of which become more fluid under pressure. [[Category:Materials]] {{science-stub}}
