Did you know?

Did you know that the current global flat glass production volume is around 52 million tonnes per annum?

Lets do some maths :
A 1000mm x 1000mm glass item of 5mm thickness weighs 13kg.
Therefore there are 77 of these items per tonne, or 77 million items per million tonnes

Therefore the total world production of glass, if it was of glass items 1000mm x 1000mm x 5mm, would be just over 4 billion items. 

To put that in perspective if we stacked those 4 billion glass items on top of each other laying flat, it would be a 1000mm x 1000mm pillar rising 20,020 kilometres tall. 20,020 kms is 20% of the distance from the earth to the moon.

That's a lot of glass!
