Grain Pattern

Appears mostly straight to irregular, with coarse texture and possible broad rays; the shown face is weathered, so figure and cut orientation are unclear.

Color & Appearance

Weathered medium-to-dark brown throughout, likely originally pale tan heartwood with lighter sapwood; prolonged light and exposure have darkened the surface.

Hardness (Janka)

Approximately 1,360 lbf (Janka), Hard.

Durability & Decay Resistance

Durable: good resistance to decay when dry, but sapwood is more vulnerable to insects and moisture.

Value & Age

Estimated Market ValueNot an official valuation

Roughly €4–12 per board foot for ordinary dry oak; figured or exceptionally clear stock costs more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
The board’s age cannot be determined reliably from the photograph; surface weathering suggests exposure rather than necessarily old wood.

Common Uses

Furniture, flooring, cabinetry, beams, barrels, veneer, and outdoor construction.

Geographic Origin

Native across much of Europe, including Slovenia; common in lowland and mixed forests.

Workability

Machines and finishes well, though coarse grain can tear out; high tannin content may stain steel and react with iron fasteners. Pre-drilling is advisable.

Finish Recommendations

Sand evenly and seal with oil, hardwax oil, lacquer, or polyurethane; use stainless or galvanized hardware to reduce black staining.

Notable Features

Heavy, strong, ring-porous wood with prominent rays and characteristic oak grain; noticeably denser than spruce.

Notes

Found in Slovenia in forest. Heavier than spruce and spine for example.
