Electrical discharge mb-artistname Wenceslaus Hollar By the late 1950sPatterns produced by electrical discharges on surfaces revealed by dusting with powdered red lead and sulphur. Sometimes termed 'Lichtenberg figures'. These experiments were conducted at Cragside in Northumberland, England, using a Wimshurst machine (electrostatic generator) and two 10 gallon Leiden jars. Current was conveyed to two rod conductors with a spark gap at which coated wires discs or plates were positioned. Lord Armstrong exhibited figures
