Flotation Process of Archaeology UW-La Crosse

To recover very small artifacts and charred seeds and nuts, soil is "floated." In this process, the soil is dried, then poured into a bucket of water. Charcoal and other plant materials are lighter than the soil, and float to the surface. They are poured off into a screen with holes of

Flotation Techniques for the Recovery of Small-Scale

Abstract. This paper outlines the procedures and equipment necessary for applying a simple flotation technique to recover animal bone, seeds, and other small cultural remains lost in the normal screening of soils from archaeological sites. Soil is initially processed in the field by a water-separation technique.
