Abstract from DBPedia
    Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the denser liquid of the mixture behind. An incomplete separation is witnessed during the separation of two immiscible liquids. To put it in a simple way, decantation is separating immiscible materials by transferring the top layer to another container. The process does not provide accurate or pure product.

    デカンテーション（英: decantation）は、容器を移して沈殿物と液体を分離する操作。傾瀉（けいしゃ）とも呼ばれる。上の不純物が少ない液体を上澄み、底に沈んだ沈殿物は澱（おり）と呼ばれる。
