A water separation, or flotation, machine is an instrument that divides soil into three components: the material that floats (called flot or light fraction), the stones and other heavy portions that do not float (called residue or heavy fraction), and the particles that either dissolve in water or become suspended in it and are washed away. The primary purpose for utilizing such a device is the recovery of organic remains, such as charred seeds, charcoal, or small bones, which would otherwise be permanently lost. However, the machine is of great value for archaeological excavation because it allows for the collection of tiny artifacts of all classes, it divides them by size and weight, and it does not break fragile items. Water separation is very different from water screening. Use of a water separation machine requires four stages in the recovery of archaeological material: 1. Retrieval of archaeological sediments 2. Operation of the water separation machine 3. Sorting of the materials 4. Study of the materials.
