Yes think of something more in the lines of Plexiglas. https://en.wikipedia.org/wiki/Poly(methyl_methacrylate)

The video is down here, looks almost like a gooey liquid how it melts back together... http://www.asahi.com/ajw/articles/AJ201712150041.html

This is a better link IMO: https://phys.org/news/2017-12-semi-transparent-polymer-room-... And here's the actual paper all the articles are about: http://science.sciencemag.org/content/early/2017/12/13/scien...

Ok, we've changed to that first link from http://www.enca.com/technology/japanese-inventor-shatters-ex.... Thanks!

If it’s non crystalline then yes, glass is defined as a non crystalline amorphous solid and there are more than a handful of plastics that fall into that category.

Plexiglas is a type of glass, it’s non silicate based but glass non the less.

What is the distinction between amorphous and non-crystalline? Also, for instance, aren't all solid metals amorphous non crystalline solids?
