Violet Smoke Method #1

  • 1 part powdered zinc
  • 4 parts powdered iodine
  • wash bottle or dropper bottle filled with water
  1. Separately powder the zinc and iodine, using a mortar and pestle.
  2. Mix the ingredients in a shallow dish.
  3. Perform the demonstration by spraying a stream of water onto the powdered mix. Violet vapor will immediately form. You may wish to place a white board behind the dish to make the violet smoke more visible.

Violet Smoke Method #2

  • 4 grams powdered ammonium nitrate
  • 4 grams powdered zinc
  • 1/2 gram iodine crystals
  • wash bottle or dropper bottle of water
  • Powder the materials separately, then mix them together in a shallow dish.
  • Initiate the reaction between the zinc and ammonium nitrate by spraying water onto the powdered ingredients. Iodine will sublimate in the heat of the reaction. White Smoke Chem Demo | Easy Violet Fire
