Did you know that until the 1500s, most glass that was made had a cloudy look? Clear, colorless glass wasn't invented until the 1500s, and it didn't become popular until the 1700s when people started using it for windows. Clear glass is very common today, but not all of our glass is clear. We also use a good amount of colored glass and clouded glass as a population.

And glass has a wider array of uses than ever before. There are entire buildings made from glass, marbles and other toys made from glass, and even fake eyeballs made from this hard material.
