Black Flame is a multichrome black/magenta/red/bronze polish with silver magnetic pigment and a sprinkle of very thin, black holo glitter to keep the base color deep instead of adding silver holo. This gives the polish a mysterious depth and it's very hypnotising in the sun.
(Last photo shows it unmagnetized, gives it a gunmetal look and you can still see the red shift.)
This can be used magnetized or not. We recommend 1-3 thin coats on it's own or 1-2 medium coats for coverage. It can also be used as a topper, 1-2 coats over black. We have a 1 coat black in our shop called Nevermore that would work great for layering.
Application tips: For a crisp magnetic effect we recommend applying colors one finger at a time so that each finger can be magnetized. Follow up with one of our quick dry top coats - Baroness X Liquid Crystal Top Coat or Assimilate, applied one finger at a time and use the magnet to keep your design sharp.
Our "hack" to getting a crisp magnetic line is to get a stronger neodymium bar and rest your fingers on top of the bar while you paint and while they dry.
