• Resumen

  • We usually think of glass as a good electrical insulator; this, however, is not always the case. There are several ways to show that glass becomes conducting at high temperatures, 1,2 but the following approach, devised by Brown University demonstration manager Gerald Zani, may be one of the simplest to perform.
