Iron wire explosion pattern Size:M: 60 x 45cm 2: 'Wherein is proposed aTwo figures of effects produced by the explosion of iron wire positioned over a sheet of paper or glass when subjected to a high voltage electrical current. This was provided by the electrostatic generator and associated machinery designed by John Cuthbertson (bap. 1743 d. 1821) for Martin van Marum and installed at Teyler's Museum at Haarlem in the Netherlands.
