What is done to anneal glass?

In: Science, Chemistry [Edit categories]

Answer:

The glass soaks in heat, typically about 960° F, to give the molecules a chance to settle down. The thicker the glass the longer it should anneal. Typical annealing times for 1/4" plate glass might be a few hours. Improperly annealed glass is more subject to fracture with subsequent temperature changes.
