Limescale - Wikipedia

Limescale is a hard chalky deposit, consisting mainly of calcium carbonate (CaCO3), that often builds up inside kettles, hot water boilers, and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where "hard water" has evaporated. The colour varies from off

For this purpose it usual to use steam or hot water in what amounts to a blanching operation and will necessarily mean contact of a water phase with the expelled oil. The nature of the liquid mixture is such that phase separation may become a real problem, and advantage must be taken of the enhanced separability occurring at higher temperature.
