No it's not.

The thing about old glass is that the manufacturing process was different and produced glass with variable thickness.

    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.
