The lacquer composition could have more coloring agent in it than most.
Any indication of the brand of blank?

Recently I acquired a number of glass based records. Or I think they are
glass. Some say they are glass. They are flat like glass. They weigh
like glass, sound like glass when you tap them lightly with your
fingernail, and looking at the edge of the center hole, I don't see
anything that looks shiny like aluminum. Dates are 1944, which would be
the right time frame for glass.
But when I attempt to shine a bright flashlight or a red laser thru
them, they are opaque, even in a very dark room at night.
Is there some reason why a glass based disc would not pass light?
