![]() ![]() ![]() But I had read somewhere that it's not true. I had always liked the idea that glass was actually a liquid that moved so very slowly that it might as well be solid. One of the characters in Sweet Home Alabama (the movie) did this, although the sculptures they showed as his lightning sand creations don't really look like what this really looks like. I also really like the shapes that lightning makes with glass, which are sometimes refined and then sold as glass art. ![]() One of the reasons glass is such a good art material is that it softens like this when it is heated, so it can be blown into thin and lovely shapes, rather than needing to be poured into a mold or hammered into shape like metals are. July 3, - I wonder if that theory has got something to do with the fact that one of the conditions in the definition of an amorphous solid is that is has to soften rather than become a liquid when it is heated.
