Grain Pattern

Straight to wavy grain dependent on cut; shows prominent medullary rays when quarter-sawn. Large, coarse pores create a distinct ring-porous texture.

Color & Appearance

Durable; excellent resistance to rot and heartwood decay, though sapwood is susceptible to insect attack.

Value & Age

Estimated Market ValueNot an official valuation

$6.00 - $12.00 per board foot depending on width and grain figure.

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

Wood Age Estimate
Roughly sawn boards appearing to be air-drying for 1-3 years based on surface oxidation and minimal graying.

Common Uses

Furniture, flooring, cabinetry, barrel making (cooperage), heavy construction, and boat building.

Geographic Origin

Europe and Asia Minor; widely native and harvested in the Czech Republic.

Workability

Generally easy to work with tools, though it has a high shrinkage rate. Responds well to steam bending. High tannin content can cause blue-black staining if in contact with iron and water.

Finish Recommendations

Takes stains and finishes well. Polyurethane or oils (Tung/Linseed) are recommended to highlight the grain. Reacts with ammonia for fuming to create dark, historic finishes.

Notable Features

Distinctive acidic scent when wet. Contains high levels of tannins. Exceptional strength-to-weight ratio and classic 'flecked' appearance on radial surfaces.
