Mean SANS tilting angle (angular axis) against isotropy (radial axis), measured in the tangential plane, for 50 archaeological samples. GSW: Grey Grainy Surface Ware; MTW: Marble Tempered Ware; OWM: Other Wheel-Made; OHB: Other Hand-Built. Black dots represent samples with macroscopically visible wheel-traces, and white dots represent samples without any traces of wheel use. Yellow zones: wheel-throwing, with clockwise (positive quadrant) or anticlockwise (negative quadrant) wheel-rotation; Green zone: coil-building and coil-wheeling; Grey zone: percussion-building.
