I remember "dope thinners" was required.

I'd quite like to find a copy of that book, or article.
My first attempt at a wimshurst machine used 12" 78's The machine would simply not work. I mentioned this to my physics lecturer at Tech He replied "Of course it wouldn't, the carbon filler in the 78's would be sufficient to be conductive at electrostatic voltages!"

My second attempt a year later using perspex discs worked fine.
