Glass: Neither a solid nor a liquid, this common yet complicated material is still surprising scientists

Due to the slow rate of change, the myth that old windows are thicker at the bottom due to centuries of gravity pulling on the slowly flowing glass is not true

Happy to see this being mentioned in the article, for some reason I keep finding this myth frequently repeated by a lot of people, some of which should know better.

As the article describes, glass is a very interesting material on its own, without having to make up fantastic properties around it.

kudos to JT for posting a scientific article from time to time.

Over 1 billion years, a typical piece of glass will change shape by less than 1 nanometer – about 1/70,000 the diameter of human hair. 

There's my WTF moment of the day.

I guess, Wandora has the point. lol

Neither is glass liquid at room temperature, nor will it ever change shape a nanometer through “relaxation” , because there was no glass a billion years ago and there also will be no glass in a billion years from now.

Nice article, JT! I too hope for more scientific content here, given that we live in Japan, country with extremely advanced research. Yes, glass is probably the most important material our society can produce and very often overlooks (due to its tranparency ;) ? ) nice to have it described as good as here.
