Quick Answer
Fatwood, derived from pine resin-rich stumps and roots, contains a higher resin content than most other woods, typically ranging from 10% to 20% resin by dry weight. This high resin content contributes to its ease of ignition and sustained burn. In comparison, other woods usually have lower resin percentages.
Characteristics of Fatwood
Fatwood is distinguished by its high pine resin content, which can reach up to 20% of its dry weight. This characteristic is crucial in fire starting, as resin burns readily when exposed to heat. To identify fatwood, look for pieces that have a dark, sticky substance on the surface, and a distinct, pungent pine scent.
Comparison with Other Woods
In contrast, other woods have lower resin content. For example, oak firewood typically contains 1-3% resin by dry weight, making it more difficult to ignite and sustain. Other softwoods, such as fir or spruce, may contain slightly higher percentages of resin, but still nowhere near the levels found in fatwood. When selecting firewood, it’s essential to note the specific type of wood and its resin content to ensure optimal performance.
Fatwood Selection and Preparation
When selecting fatwood, choose pieces with visible signs of high resin content, such as sticky surfaces or a pungent pine scent. Cut the fatwood into manageable pieces, about 1-2 inches in length, to facilitate easy ignition. To prepare fatwood for use, shave off any loose wood fibers to expose the resin-rich core, and store it in a dry, protected area to preserve its effectiveness.
