Anachron, 
#TIL that we produced "Superfest" glass in Germany in 1970 but the market did not want it because it lasted too long.
Fun fact: The Gorilla Glass on your phone is actually using the same process that we created back 50 years ago.
In fact, the more I find out why the world is like it is now the more depressed it becomes.
What a world we live in. Money, greed and planned obscolence everywhere you look.
