In Fig. 10 we present the relation between diameter and thickness for ‘Vădastra
2’ pottery. The dispersion of the location increases with their thickness. For an average
diameter of 258 mm the tolerance is 73 % and increases at the same time with the
diameter. That increase proves that for the excised pots, the diameter–thickness ratio is
lower as the pots are larger.

‘Vădastra 2’ pottery from Vădastra.
The IN/EX pots have preserved this pattern approximately (Fig. 11) with
tolerances up to 300 %.
In order to assess the even thickness of the walls of the pots the modelling index
was assessed as a standard deviation of the individual measurements for the calculation
of the sherds thickness 40 . The tightest modelling index–thickness relation is the parabolic
one, but this relation is much looser than the porosity index–thickness and diameter–
thickness ones (Fig. 12). That proves that the potters were not concerned with modelling
pots with walls of the same thickness.
