Fatwood (Resinous Pine)
Pinus spp. (predominantly Pinus palustris or Pinus elliottii) • Softwood
Grain Pattern
Straight to irregular grain depending on the specific branch or stump section, with heavy resin saturation obscuring the natural tracheid details. Shows flat-sawn surface characteristics.
Color Description
Heartwood is a rich, translucent amber to dark reddish-brown due to high resin concentration. Sapwood and less saturated areas appear pale yellow to light tan. Darkens significantly with age and oxidation.
Hardness Rating
690 - 870 lbf (Soft to Medium); though technically softwood, resin saturation significantly increases density and perceived hardness compared to standard pine.
Durability Rating
Very Durable (for a softwood). The extreme resin content acts as a natural preservative, making it highly resistant to rot, fungal decay, and insect attack.
Common Uses
Fire starter (kindling), survival kits, traditional torches, and occasionally small rustic turnings or heavy-duty outdoor stakes.
Geographic Origin
Southeastern United States (specifically the Coastal Plain), and other regions where longleaf or slash pines are native.
Market Value & Sustainability
Estimated Market Value
$2.00 to $5.00 per pound (typically sold by weight as kindling rather than board feet). High-grade resinous chunks are more valuable.
Wood Age Estimate
Old-growth stump or deadwood remnant; the wood itself may have been harvested or found recently, but the tree likely lived 50-100+ years before falling.
Sustainability Status
Extremely sustainable; typically harvested from the stumps of long-dead trees (stumpwood) or fallen limbs. Not CITES listed.
Workability
Difficult to work with tools because the high resin content clogs sandpaper, gums up saw blades, and sticks to planer knives. It glues poorly due to natural oils but holds fasteners well.
Notable Features
Strong, pleasant turpentine or balsamic pine scent. Highly flammable; catches fire easily and burns very hot. Very heavy and dense compared to standard pine. Resin is sticky when handled.
Finish Recommendations
Usually left unfinished to preserve scent and functionality. If used for craft, use a dewaxed shellac (Zinsser SealCoat) to seal in resins before applying other topcoats.
Identification Confidence
High. The characteristic amber translucency, heavy longitudinal resin streaks, and 'greasy' appearance are definitive of fatwood/pine knot material.
