Quick Answer
Fatwood is prized among survivalists and campers due to its high combustibility and durability. When dried properly, fatwood is essentially waterproof. This property makes it an ideal fire starter in wet conditions.
Fatwood Identification and Harvesting
To identify fatwood, look for resinous dead branches or trunks, typically found in pine or spruce trees. These trees produce a type of sap called pine resin, which hardens upon exposure to air, creating a waterproof, waxy substance. Fatwood is usually the driest and most brittle part of the tree, often with a light or dark brown color.
Harvesting fatwood requires care. Cut a small branch or a piece of bark, and let it dry in a shaded, well-ventilated area. Fatwood can be dried in as little as 30 minutes to an hour, depending on the humidity and temperature. A general rule of thumb is to dry fatwood in a warm, dry spot protected from the elements.
Preparing and Using Fatwood for Fire Starting
To prepare fatwood for fire starting, shave off small strips using a knife or a sharp rock. Fatwood shavings are usually thin, brittle, and can be easily lit with a match or a lighter. In a survival situation, you can also use a hand drill or a bow drill to create an ember and ignite the fatwood.
When using fatwood, keep in mind that it burns hot and fast, producing a high-quality flame. To conserve fatwood, use small amounts and combine it with other dry tinder and kindling. A general rule of thumb is to use 1-2% fatwood in a fire, as excessive fatwood can create a fire that’s too hot or hard to control.
