Sampling methods for ancient starch analysis: stone tools

Sampling method Posted by Picasa

The two major methods used elsewhere have been spot sampling with water in a micropipette or immersion of stone tool in a sonic water bath. At present, spot sampling is relied to learn exactly how starch is distributed on tool surfaces.

Spot sampling from tool surfaces is mainly focusing on residues embedded in crack and depressions on tool surfaces. At this step taking samples, it is not sure that these samples contain ancient starch.

1) Basic set of sampling equipment (sterile water, disposable tips, sampling tubes, 10-100μl pipette)
2) Crack with residues
3) Removing residue with water
