Glass is a mysterious substance. I never realized how interesting it was until I took a class in fused glass from Maggie Spencer, a Sawdust artist.
Glass, as Maggie explained to our small "Girls Night Out" class, is neither liquid nor solid. It's "amorphous," or formless.
Yet glass is one of the most common substances in our lives. If you look around, you'll see at least two to three, or more, forms of glass on your wall, on your desk, on your kitchen table.
It's not "formless" at all; it's able to take many forms.
And yet, as Maggie explained, when left to its own devices, glass tends naturally to take a quarter-inch, round shape. That's what it wants to be, and over time, glass will "melt" into a roundish shape, such as the glass on an antique piece of furniture or windows on a very old house. It will ripple and lose its hard edge as it succumbs slowly to gravity.
