Grain Pattern

Typically straight and regular, though wavy or curly grain can occur. The end grain shows a ring-porous structure with distinct growth rings that create a strong cathedral pattern when flat-sawn.

Color & Appearance

Heartwood is usually a light to medium brown, while sapwood is wide and can be beige to light brown; not always clearly demarcated from heartwood. This log shows significant dark staining in the center, likely 'Olive Ash' coloration or bacterial wetwood.

Hardness (Janka)

1,320 lbf (Hard)

Durability & Decay Resistance

Non-durable, perishable. Poor resistance to decay and insect attack, especially when in contact with the ground.

Value & Sustainability

Estimated Market Value
$5.00 - $9.00 per board foot depending on grade and presence of 'Olive' figuring.
Wood Age Estimate
Based on the diameter and visible growth rings, the tree is likely between 40-60 years old; the log appears recently felled (within months) given the moisture in the wood and lack of significant check cracking.
Sustainability Status
Currently threatened by Ash Dieback (Hymenoscyphus fraxineus) in Europe; listed on the IUCN Red List as Near Threatened.

Common Uses

Flooring, tool handles (due to high shock resistance), baseball bats, furniture, cabinetry, and veneer.

Geographic Origin

Europe and Southwestern Asia.

Workability

Generally excellent workability; produces good results with both hand and machine tools. Responds well to steam bending. Glues, stains, and finishes well.

Finish Recommendations

Responds well to all types of finishes. Because of its large open pores, a grain filler is recommended if a smooth, glass-like finish is desired.

Notable Features

Distinguished by its superb toughness and shock resistance. It has no characteristic odor. The dark center in this specific log is a sought-after aesthetic known as Olive Ash.
