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 INSTAP Archaeological Excavation ManualArchaeologyMethodologyArchaeologyFieldworkExcavations (Archaeology)FlotationSoilsAnalysisElectronic books.ArchaeologyMethodology.ArchaeologyFieldwork.Excavations (Archaeology)Flotation.SoilsAnalysis.930.1Peterson Sarah E.1983-914450Betancourt Philip P.1936-208786MiAaPQMiAaPQMiAaPQBOOK9910452264403321Retrieval of materials with water separation machines2121626UNINA
