6.3 Sample for analysis

Altogether we included 121 artefacts in a spreadsheet, with a total of 179 edges (many artefacts having more than one used edge), 99 of the 107 artefacts from the three nodules (A, B, and C), whose manufacture and use were recorded in the field, were analysed microscopically. Eight artefacts were not included – six were missing from the collection, one was broken and one was impossible to study under the microscope owing to its shape.

An additional 22 artefacts were analysed from those given or sold to us; their probable uses recorded. Most of the other artefacts in the bought or given assemblage were either too large to examine under the microscope or there was no use recorded for them. Six tools were hafted, the remainder were unretouched flakes.

The variables used in the analysis are as follows:

  1. length, width, thickness and mass of the artefact
  2. edge angle, edge length, edge thickness (Figs 6, 7, 8 and 9)
  3. edge profile, number of used edges (Fig. 10)
  4. artefact shape (Fig. 11)
  5. dorsal and ventral macro fractures (absent; <5 per 10mm; >5 per 10mm)
  6. dorsal and ventral macro fracture type (flakes, snaps, steps) (Fig. 12)
  7. edge rounding
  8. dorsal and ventral micro fractures (absent; <5 per 10mm; >5 per 10mm)
  9. dorsal and ventral micro fracture type (flakes, snaps, steps, flakes and snaps) (Fig. 12)
  10. dorsal and ventral micro rounding (absent, heavy, light)
  11. dorsal and ventral microtopography (flat; undulating; ridged) (Figs 13, 14)
  12. dorsal and ventral polish distribution (continuous; intermittent; absent) -dorsal and ventral polish distribution type (away from the edge; gapped; edge only even; edge only asymmetric; differential; absent) (Fig. 15)
  13. dorsal and ventral polish invasiveness (edge only; <0.5D; >0.5D; absent) (Fig. 16)
  14. dorsal and ventral micro linear features (parallel; perpendicular; angled; parallel and perpendicular; parallel and angled; perpendicular and angled; absent) (Fig. 17)
  15. dorsal and ventral microstriations (parallel; perpendicular; angled; parallel and perpendicular; parallel and angled; perpendicular and angled; absent) (Fig. 18)
  16. dorsal and ventral polish development. [A (individual pockets); A+ (large unconnected individual pockets); B (linked pockets); B+ (greater linkage between pockets); C (all over polish); D (linear)]. (Fig. 19).
