The origins of glass date back to 3,500 BC but it wasn't until the Roman Empire, 2,000 years ago, that the art of glass-blowing and the practical uses of glass became more widespread.

We were simply too busy to join book clubs, take glass-blowing classes, or even stay late at the office.

A special process in the glass-blowing causes greater space between the molecules of the glass, leading to more surface area.
