Re: [ARSCLIST] vinyl 78's

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.
I've seen some postings suggesting styrene rather than vinyl. More brittle,
