Lead corrosion dating

While reading about an ancient Roman technique for maneuvering heavy stones using lead lumps, Prof. Shimon Reich of the Weizmann Institute's Materials and Interfaces Department came up with an idea: The age of ancient lead could be determined with the help of superconducting properties. To put his idea to work, he enlisted the help of a metallurgist - Dr.

A methodology for dating archeological lead artifacts based on the voltammetry of microparticles is described. This methodology is based on the comparison of the height of specific voltammetric features from PbO 2 and PbO corrosion products formed under long-term alteration conditions.

Calibration of the method was performed with the help of a series of well-documented lead pieces from the funds of different museums of the Comunitat Valenciana Spain covering from the fifth century B.
