    $\begingroup$ It might be a bad example for this particular use case, as you have to insulate the wire before winding it and lacquer would crack. If you have any wire that you could insulate in place though, it's not a bad option. $\endgroup$ Commented Nov 13, 2019 at 0:04

    $\begingroup$ "Other types of insulation such as fiberglass yarn with varnish, aramid paper, kraft paper, mica, and polyester film are also widely used across the world for various applications like transformers and reactors. In the audio sector, a wire of silver construction, and various other insulators, such as cotton (sometimes permeated with some kind of coagulating agent/thickener, such as beeswax) and polytetrafluoroethylene (Teflon) can be found. Older insulation materials included cotton, paper, or silk, but these are only useful for low-temperature applications (up to 105°C)." $\endgroup$ Commented Nov 13, 2019 at 0:33

  • $\begingroup$ If you lacquer paper or cloth and only heat it after it is wound it should work well. lacquer does take a long time to dry, easily long enough to wind the wire. $\endgroup$ Commented Nov 13, 2019 at 14:35
