Liquid crystals are a state of matter (phase) that have properties between those of a conventional liquid and those of a solid crystal. Shown here, the phase transition (liquid/solid) is occurring. A sample of the material was placed between two crossed polarizers; the sample was then heated and cooled. The crystal and liquid crystal phases will both polarize the light in a uniform way, leading to brightness and color gradients.
