Quick Answer
Fatwood can be differentiated from other wood types by its high oil content, distinctive piney aroma, and light, fluffy texture. It typically has a higher density than other woods, which can be tested by weighing or measuring a given volume. This helps ensure the right type of wood for making fire starters.
Identifying Physical Characteristics
Fatwood is typically lighter than other types of wood due to its higher oil content, with a density that can range from 0.8 to 1.2 g/cm³. To verify this, you can weigh or measure a given volume of fatwood and compare it to the same volume of other wood types. For example, a 1-inch cube of fatwood might weigh around 6.1 grams, while a similar cube of dry oak might weigh around 5.4 grams.
Observing Aromatic Properties
Fatwood has a distinctive piney aroma that is often more pronounced than other types of wood. This is due to the presence of terpenes, which are naturally occurring oils that give pine trees their characteristic scent. To identify fatwood by its aroma, you can simply crush a small piece of the wood and inhale the resulting fragrance. If the scent is piney and strong, it’s likely fatwood.
Testing with a Magnifying Glass
Examine fatwood under a magnifying glass to observe the patterns of resinous streaks left behind on the surface. Fatwood tends to have a more pronounced, waxy appearance due to the high oil content, whereas other wood types may appear more dry and porous. This can be a useful test in the field, especially when other distinguishing characteristics are not immediately apparent.
