What were typical white dyes/pigments for lacquer in the 1950s?

Excuse me posting a non-electronics thread in an EE forum, but I think most electronics projects would require paint at some point. And I could call it an electronics topic thread by saying "conductive dyes for better EMI shielding?  "
 
anyway, does anyone know what were typical white pigments/dyes used for white lacquer, specifically automotive nitrocellulose lacquer.
my first thought was lead carbonate, but was it used for lacquers too? not just oil paints?

Yes you used lead carbonate, though more modern ones use titanium dioxide instead, as it is a lot less toxic, and more reflective as well. You just have to use a lead paint tester on the old paint to see just how much lead is in it.

Titanium Dioxide didn't really see widespread use until the toxicity of lead became better known, probably because of cost. So up until the 1960s or so, anything that's painted white might still have used lead carbonate as the pigment. Not everything needs automotive grade paint.
