7/11/2017· Soil flotation: A DIY approach Post-excavation analysis is the underappreciated sister of excavation–less glamorous and exciting–but absolutely fundamental to making sense of a site. Here at the Achill Field School we like to give our students a taste of all aspects of the archaeological process, so this morning we rolled up our sleeves for ...
The method is more controlled than flotation by machine, and the recovery rate is better. For large-scale excavations, machines are used. Operating principles vary: samples are poured into a large container of water, or water and paraffin, which is agitated by air injection or by currents of inflowing water.
These Old World flotation machines inspired the development of flotation machine design as part of the Shell Mound Archaeological Project in the American mid-west, and the so-called SMAP-type machine has become a standard baseline from which many flotation machine designs have been developed, e.g. in China. Watson, P. J. 1976.

Flotation rates for the customized Flote-Tech system ranked high, matching flotation rates for SMAP systems and out-performing manual IDOT systems by a factor of four to eight. In addition, a distinct advantage of the Flote-Tech system over other machine-assisted and manual systems is the elimination of cross-contamination between samples.
The flotation machine described here is based on a design innovated by Patty- fo Watson for use on her Shell Mound Archaeological Project in Kentucky in the 1970's (Watson 1976).What has since become known as the "SMAP-type flotation machine" was later refined by Gary Crawford (1.983:53), who improved the means for sludge disposal and ...

They will be floating dry sediment …
by Laura Shick: Flotation 101. I'm in charge of the flotation laboratory at Mount Vernon this summer. Flotation provides archaeologists with insight into people's diet and agricultural practices, as well as information on past environmental conditions. We hope soil from the distillery will yield some of the grain that was used to produce whiskey.
This is typical froth flotation machine, often constructed from an old oil drum. It is also known as a Siraf-type flotation machine. Flotation machine at Giza, Dr. Mary Anne Murray hard at work.

The flotation method vastly improves the amount of information archaeologists can retrieve from soil samples at a site, in particular with respect to the diet and environment of past societies. By the way, this machine is called a Flote-Tech, and as far as I am aware, it is the only manufactured flotation machine available on the market.
You can see demonstrations of our flotation process during special events like the Winter Village Family Fun Day being held on February 17, 2014 and Wilfrid Jury Archaeology Day in July. You can also check out these videos that demonstrate the Bucket and Machine flotation techniques.
