Re: [ARSCLIST] Glass Records

And in my experience, glass based discs seem far less prone to palmitic 
acid.

Interesting statement, and one I had not heard before. We just finished 
surveying a few lacquer discs (almost all US), so just for fun I tried 
to run a query.

Of 1,925 with metal substrate, 375 have evidence of palmitic acid (19%). 
Of 123 glass-based, 22 have evidence of palmitic acid (18%).

"Further research is necessary", as they say ;-)
