Hi, and happy new year all,

I'm just curious - what can I distinguish shellac 78rpms from
other thick vinyl-made 78rpms, not only by reading labels saying
such as "Merco Plastic" or "Non-breakable"?

The last era of vinyl 78rpms can be easily distinguished just
because they are very thin and flexible. But other type of vinyl 78rpms,
as well as very early LPs, are not flexible and rather thick.
I've been wondering whether the last era of thick 78rpms (late 1950s
to early 1960s, for example) are actually made either of shellac
or thick vinyl.
