Electrical resistivity

Electrical resistivity

See soil resistivity. A standard cleaning process in archaeological conservation. artefacts are placed in a chemical solution, and by passing a weak current between them and a surrounding metal grill, the corrosive salts move from the cathode (object) to the anode (grill), removing any accumulated deposit and leaving the artefact clean.
