Re: [ARSCLIST] identifying acetate substrates

[Steven Smolian <smolians@xxxxxxxxx>]

What we forget is that not only was aluminum unavailable for use as the base
of lacquer records during the war, but so were many chemicals.  Thus the
makeup of the lacquer may well be different froim that used earlier.  I've
seem memos from RCA addressing this issue.

That means that cleaing and chemical restoration products may affect them in
unexpected ways, the most unexpected is that the old ways may not work at
all.

Answer to David's question re: use of glass in Canada in 1940.  Canada was
at war before the U.S. was and may have been getting blanks from elsewhere.
Were convoys coming back empty?  An interesting historical question.
