analog newbie question/vinyl weight

Rushton, FYI - "virgin vinyl" as a marketing concept is not a product of the '80s. I have a bunch of Longines Symphonette LP sets from the '60s that promote their virgin vinyl materials. I'm sure this was not new in the '60s or exclusive to Longines Symphonette.

regarding steve hoffman's preferences for heavier vinyl, he has stated on his own website his dislike for 200g. and i don't know if the thickness of vinyl has anything to do with it, but there is enough complaints about the quality of classic's 200g releases (although i've never had any problem with them) to make you wonder if 180g is good enough. open for ongoing discussion...

What is "Quiex II" Vinyl? and is it just a special formulation?
Figure this is a good point to ask at the spot!
And who sells the basic vinyl supply? Like do they buy 55 gallon drums. 100lb blocks... 100 pound bags of pellets???

Rex - interesting, I'd never seen the use before the 80s.

Elizabeth - "Quiex II" is stated by Classic Records to be a different formulation, but they are all somewhat different from pressing plant to plant. Some of CR's re-releases on Quiex II do sound better than the earlier releases with a somewhat sweeter top end that improves somewhat on the notoriusly poor CR string tone (they haven't been remastered, so the vinyl is the only change). As I understand the process, the vinyl comes in pellet form.

Elizabeth,

A dealer friend gave me a "Hershey Kiss" piece of vinyl years ago. I don't really have any way to confirm this now but he told me it was a genuine piece of MFSL vinyl as they purchased it, ready for the stamping process. It does look exactly like that particular piece of candy. It has been sitting close to my turntable since the early 80's as a novelty. It's about 3" in diameter by 1 1/2" tall.
