At Which Temperature Does Glass Melt?


Quick Answer

Although it technically depends on the exact molecular makeup of the glass in question, glass typically melts between 2,500 degrees Fahrenheit and 2,900 degrees F (approximately 1,400 - 1,600 degrees Celsius). Certain types of glass can melt at lower temperatures, but commercial glass must reach that approximate temperature before melting.
