re: #86 jaunte

It’s a fascinating read, although they get a number of things incorrect. I am not terribly surprised, since glass is a misunderstood material. If it’s flowing, it’s not glass. Glass doesn’t have a melting temperature, it has a glass transition temperature. :)

The interior of the flow is still a melt (i.e., super-cooled liquid below the crystallization point, although I can’t say for sure if the interior is totally super-cooled in this case since rock/glass can be a fantastic thermal insulator). The outside, however, is a glass - hence the breaking noises.
