Flotation is usually undertaken by an archaeo-environmental specialist, who then checks through the fraction and analyses the dried flot. Now the Trust can process our own bags of soil samples, and send just the flot to specialist Val Fryer for analysis.

Environmental Archaeology Crash Course: Flotation

Flotation is a method of processing bulk soil samples using water. Essentially, the different materials in the sample (such as the soil, the rocks/bones/artefacts, and the charred material) have different densities. When you put the whole sample in water, the soil and the artefacts sink while the charred material floats.

The Flotation Technique in Archaeology

May 03, 2012 · The aim of flotation is to “recover animal bone, seeds, and other small cultural remains lost in the normal screening of soils from archaeological sites” (Struever 1968:353). As I understand this, faunal (animal) and floral (plant) materials is trapped in soil, and is sometimes hard to distinguish in a dry sieve.
