Old glass being thicker at the bottom, isn’t what was referring to.
Maybe its a bit of a technicality, but since glass doesn’t form a crystal lattice, one could argue that its just a liquid which has an infinitely high viscosity. Hence its very viscous.
If you ask a material scientist, glass is also just a very viscous liquid.
I thought that was disproven?
No it’s not.
The thing about old glass is that the manufacturing process was different and produced glass with variable thickness.
