Quick Answer
Green birch bark is generally a better choice than papery bark for fire tinder due to its higher water content and resinous properties, which make it burn more efficiently.
Choosing Green Birch Bark
When selecting birch bark for tinder, choose green birch bark over papery bark. Green birch bark has a higher water content, typically around 30-40% moisture, making it burn more efficiently and produce a longer-lasting flame. Papery bark, on the other hand, has a lower moisture content, around 10-20%, and may not burn as well.
Preparing Birch Bark
To prepare green birch bark for tinder, peel off the thin, papery layer from the underside of the bark. This will expose the thicker, more resinous layer. Use a knife or a rock to shred the bark into fine strips, about 1/4 inch wide and 1 inch long. This will increase the surface area and aid in ignition.
Ignition Techniques
To ignite the birch bark tinder, use a drill method or a bow drill. Hold the tinder in a small nest of dry leaves or grass, and place a small stick or twig across the top. Create friction by rotating the drill or bow, generating heat and eventually an ember. Once the ember is established, gently blow on it to ignite the tinder.
