So I tried rubbing a 12" 78 with a soft cloth and it charged up and would attract scraps of paper. This was a 1946 recording.

I have a 10" 78 from 1909 and no amount of rubbing would produce a charge.
Two years ago I bought a special transparent rod from ebay, it grows purple in the dark after rubbing it with a cloth. It grows very bright purple near a Tesla coil. I can't remember what material it is made of.

When I was a kid, I used to have a ginger cat, i got good output of electrostatic charge from her furs from rubbing a plastic ruler under dry weather conditions.
