The Flotation Technique in Archaeology | - Archaeozoology

May 3, 2012 ... Flotation has always been somewhat of a mystery to me. My base understanding of what flotation entails is that you use water and sieves to separate archaeological materials from soil. As we all know certain objects are heavier than others, wood and seeds are light and thus float, stones are heavier and...

Mississippi Valley Archaeology Center: The Process of Archaeology ...

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 0.5 mm, which is finer than window screening.
