Abstract

To enhance the recovery of dense, nonfloating botanical remains, we used a siphon subsequent to the normal flotation process. The siphon vacuums the heavy fraction of a flotation sample and retrieves most of the non-floating botanical material. Experiments show an improvement averaging 9.9% and 11.3% by count and weight, respectively, for the recovery of high-density botanical remains using the siphon technique.
