Flotation forms should be used to record provenience, volume of soil, date floated, and notes (Figure 1). Before pouring the soil into the flotation machine, prepare two more trays by lining them with newspaper and writing the provenience data for the soil on the paper. One will hold the heavy fraction and the other will hold the light fraction

Jan 20, 2017 This system uses water recirculation in a closed loop between a water reservoir and a flotation tank, aided by diffused air, to extract archaeological botanical remains from soil samples. The paper presents two experiments conducted to assess macroremain recovery rate, flotation rate, and the potential for cross-contamination between soil samples

Jul 31, 2003 The flotation tank holds 100 gallons of water, and requires electricity to run a pump to keep water flowing through the soil so that the sediment breaks into fine particles and artifacts float to the surface. The flotation tank was soon working beautifully. However, it can only store 113 liters of sediment, so I had to figure out how to empty
