Quick Answer
To safely process inner bark for fire making, strip the bark from the tree using a sharp tool, then dry it by cutting it into thin strips and laying them out in a single layer. This can take several hours or days, depending on the ambient temperature and humidity. Once dry, the inner bark can be used as tinder.
Preparing the Bark
When selecting trees for inner bark, look for species like cedar, cypress, or pine, which contain oils that help ignite more easily. Use a sharp knife or hunting knife to carefully strip the bark from the tree, working from the base of the trunk upwards. Be mindful of any branches or knots that may cause the bark to tear.
Drying the Bark
Cut the bark into thin strips, no thicker than 1/8 inch (3 mm), to promote drying. Lay the strips out in a single layer on a flat surface, such as a rock or a piece of bark. It’s essential to maintain airflow around the strips to speed up the drying process. If the ambient temperature and humidity are high, it may take 2-3 days for the bark to dry completely. However, in cooler, drier conditions, it may take up to a week or more.
Storing and Using the Tinder
Once the inner bark is completely dry, store it in a dry place, away from any moisture. When you’re ready to use the tinder, simply crumble it into smaller pieces and use it as you would any other tinder material. The inner bark of certain trees can produce a hot, long-lasting fire, making it a valuable resource in a survival situation.
