<P> A centrifuge may also be used in decantation as the natural process of settling down is time consuming and tedious . A centrifuge forces the precipitate to the bottom of the container; if the force is high enough, solids can aggregate to form pellets, making it easier to separate the mixtures . Then the liquid can be more easily poured away, as the precipitate will tend to remain in its compressed form . </P> <P> Decantation is frequently used to purify a liquid by separating it from a suspension of insoluble particles (e.g. in red wine, where the wine is decanted from the potassium bitartrate crystals to avoid unsavory taste). This makes the wine more tonic and astringent . </P> <P> Cream accelerates to the top of milk, allowing the separation of milk and cream . Fat is determined in butter by decantation . </P> <P> To obtain a sample of clear water from muddy water, muddy water is left in a container until the mud settles, and then the clear water is poured into another container . </P>
