This is a video in which we charred natural materials to make a fire starting aid. We took chunky rotted wood or Punk wood from an fallen oak and put it in a metal tin with a small hole in the top and then placed it in a fire. You will see smoke come out of the hole, this is normal. When the smoke stops take it off of the fire and let it cool. The charred material takes a spark very easily from a ferro rod or flint and steel. You can then use that ember to blow tinder into flame.
Once you have the charred wood you can blow it into flame.
