Grain Pattern
End grain shows distinct annual rings, diffuse-to-semi-ring porosity, and radial checking. Face-grain figure cannot be assessed from this end-cut image; no decorative figure is apparent.
Color & Appearance
Heartwood appears medium gray-brown to olive-brown, likely darkened by oxidation and weathering; sapwood is not clearly separable. Surface luster is low.
Hardness (Janka)
1,700 lbf Janka; Hard.
Durability & Decay Resistance
Very Durable: black locust heartwood has strong natural resistance to decay, insects, and weathering.
Value & Age
Approximately $8–18 per board foot for clear, dry, surfaced black locust; rough or utility stock may be considerably less.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Tree age may be roughly 30–70 years from the visible ring count, but the sample’s harvesting age and surface age cannot be determined.
Common Uses
Fence posts, exterior structures, decking, agricultural equipment, flooring, furniture, turning, and boat components.
Geographic Origin
Native to the central and eastern United States; widely planted and naturalized across North America and Europe.
Workability
Hard and wear-resistant; machines reasonably well but can cause edge dulling and occasional tearout. Pre-drilling is recommended; gluing is generally satisfactory with clean, dry surfaces.
Finish Recommendations
Sand and seal promptly to reduce uneven oxidation; penetrating exterior oil suits outdoor use, while polyurethane or lacquer suits interior work.
Notable Features
Heavy, stiff, shock-resistant wood with strong decay resistance; often develops attractive golden-brown heartwood when freshly surfaced.
