Nope.
There's virtually no scattering in modern regular glass - except maybe
for some dirt on the surface, but that's obviously not some interior effect.
Ancient glass did often have impurities that would scatter light, but as
a result the material would appear misty or even opaque at reasonable
thickness (because that's what scattering ultimately does to a medium).
