This data set contains 38 particle-size distributions (PSD) of unfired potsherds from the Iberian workshop of the Mas de Moreno (Teruel, Spain). The distributions were obtained by laser diffraction.
The PSDs were measured using a LA-950V2 (HORIBA) laser granulometer.
All the samples were pre-treated with hydrogen peroxide to remove organic matter. The samples were then dispersed in water using sodium hexametaphosphate and ultrasonication.
The PSDs were calculated using the Mie solution to Maxwell’s equation, with 1.33 as the water refractive index and 1.55-0.1i as the sediment refractive index.
