Sugar Reflotation and Curation.

Sugar reflotation of matrix containing archaeological material appears to be a relatively inexpensive, safe, and reliable method for the recovery of botanical remains. Using high concentrations of sugar to increase the specific gravity of water to make flotation viable for botanical recovery will, however, also saturate archaeological material (e.g., botanical, faunal, and some artifactual materials) with sugar that could damage the materials or attract pests that could damage the materials during curation. For this reason, samples processed using sugar reflotation should have the sugar removed bofore curation. This issue has not been previously addressed and will add to the time and expense involved in this process. [ABSTRACT FROM AUTHOR]
