However, since the dangers of ingesting lead are now well-known, today lead glass is used mainly for electrical applications because of its electrical insulating properties and lower melting temperature. When coated with an electrically conductive film, aluminosilicate glass is used as resistors for electronic circuitry. The data from the demonstration can also be used to calculate the universal gravitational constant G. Photo courtesy Clive Grainger.
Fire polishing ends will also reduce cuts and abrasions to you. Match the area of hot glass to the size of the seal. 25 amps so there is enough capacity to run other things as well.
