Lead in the Bones of Prehistoric Lead-glaze Potters

In 1932 Haury described lead-glaze pottery from the Southwest. In view of his report, it appeared desirable to find out whether the makers of such pottery suffered from lead poisoning. A series of 46 bone specimens from Kinishba, where lead-glaze pottery was made, and a control series of 33 specimens from Point of Pines, where such pottery is not known to have been made, were screened by X-ray and by X-ray diffraction. The 11 most promising specimens were then analyzed by atomic absorbtion spectrophotometry. Lead was found in quantities believed to be below the toxic range; concentrations in the control series from Point of Pines were, with few exceptions, higher than in the experimental series from Kinishba.
