Glass Is Our Legacy

Glass is the toughest man made substance. That is a pretty big statement considering we all know how easily it breaks, so give me a chance to explain.

When you break glass it is still glass. You can crush it to a fine powder, heat it up or freeze it. It remains glass. Metal however rusts, and in that process changes from iron into ferrous oxide. It becomes something else. Same with wood, it rots. Bricks break down back into their original parts. Glass however will always be glass.

Now look around. Glass is everywhere, in many different forms. There are different colours as well as different grades of glass. You can find it nearly everywhere on this planet in some form. Go into the wilderness and there will be some in the form of rubbish. It lays on ocean floors covered with corals. It has even made its way to Antartica.

Imagine in a billion years from now. Humankind has long since died out. An alien race lands on Earth. All our buildings and monuments have long since crumbled to dust. Glass however is still around. It will show them that an advanced civilization once lived here and that it spread all over the globe.

Glass is our legacy. It is here forever. Something to think about next time you are relaxing with a bottle of wine or beer.
