Flotation Method in Archaeology - ThoughtCo

In flotation, the technician places dried soil on a screen of mesh wire cloth, and water is gently bubbled up through the soil. Less dense materials such as seeds, charcoal, and other light material (called the light fraction) float up, and tiny pieces of stone called microliths or micro-debitage, bone fragments, and other relatively heavy materials (called the heavy fraction) are left behind,The Flotation Technique in Archaeology - Digging,03/05/2012· I spent the day participating in a mix of flotation (explained here) and sifting through the remains.
