Punk wood can also be used uncharred. I use it alot to sustain an ember created through firiction fire. An ember created through friction fire is fragile and small. Moving an ember like this into a tinder bundle and blowing it into flame can be risky: you can drop it and, if your tinder isn’t dry enough, there’s a risk you’ll extinguish it before it ingnites the grass. A better alternative is to place some punk wood on the ember and let it grow and build. With a much larger ember, you have more time and more chances to create a flame.
If you would like to learn how to use punk wood and charred material to create a fire why not join one of our bushcraft courses, run throughout the year. We also run courses on request for individuals, families, workplaces and schools.
