For kicks I looked up glass on Wikipedia. They know everything. And it’s interesting to see what they have to say about glass. Most of this stuff you probably knew already, but I bet there are a few things you didn’t know. It was first created in Mesopotamia in 3500 BC. Glass is an amorphous (non-crystalline) solid material. Glasses are typically brittle, and often optically transparent. Those words are directly from Wikipedia. What I love about Wikipedia is that they do give quite a bit of information about the subject and there is a bunch of reference material where you can go to find out more. I love the science of glass. If science had been as much fun in school as it is playing with glass we might all be scientists. But then again, can’t glass workers be also called scientists since we deal with chemistry and physics and other scientific types of things while working with glass? Nice question, I think.
