This is weird. Apparently, glass will melt both when it's too hot - and when it's too cold...
Here's why:
"Most of the time, not many interesting things happen once a substance gets below the temperature required for solification. Its atoms are bound to one another, and without the indroduction of some kind of energy, they'll stay that way. Glass, it turns out, is the exception. Once it gets close to absolute zero, it melts again.
But what could make that happen? The atoms in glass chilled to near-absolute zero have almost no energy, so they can't be jiggling fast enough to tear apart from each other. And yet, on paper and in computer simulations, glass returned to a liquid form when brought close enough to absolute zero.
The wild card turned out to be quantum mechanics. Once the atoms of glass became still enough, they stopped acting like particles and instead acted like waves. The wave-like atoms now were able to flow, moving through spaces too small for particles to get through. This motion, and this ability to fit through small spaces, causes ultra-cold glass to melt into a liquid. No word yet if this works on the T-1000.
