Macrobotanical Analysis - Clarissa Cagnato

This sieve will catch the lighter particles, while the heavier plant remains will stay in the bucket. Manual water flotation is usually easier to set up, especially in the field, and inexpensive. However, it can be time consuming and labor intensive, and usually does not make sense for processing very large samples of soil.

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.
