Temperature of glass melting
Web9 Dec 2011 · The range depends on the composition of the glass but is usually about 450°C. If the glass is cooled slowly through that range, so that the temperature near the surface is never very different from that of the interior, then the strain in the resulting object is much reduced. Such glass is said to be annealed.
