  "abstract": "<p>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.</p>\n\n<p><strong>Method</strong></p>\n\n<p>The PSDs were measured using a LA-950V2 (HORIBA) laser granulometer.</p>\n\n<p>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.</p>\n\n<p>The PSDs were calculated using the Mie solution to Maxwell&#39;s equation, with 1.33 as the water refractive index and 1.55-0.1i as the sediment refractive index.</p>\n\n<p><strong>Data description</strong></p>\n\n<ul>\n\t<li><em>sample:</em> sample reference;</li>\n\t<li><em>date:</em> date of the analysis;</li>\n\t<li><em>laboratory:</em> analysis laboratory;</li>\n\t<li><em>H2O2:</em> has the sample been pre-treated with hydrogen peroxide?</li>\n\t<li><em>HCl:</em> has the sample been pre-treated with chloridic acid?</li>\n\t<li><em>HMP:</em> has the sample been dispersed with sodium hexametaphosphate?</li>\n\t<li><em>ultrasonication:</em> duration of ultrasonic dispersion (seconds);</li>\n\t<li><em>0.011</em> to <em>3000.000: </em>relative amount (percent) for the given grain size (micrometers).</li>\n</ul>",
