Spalted Beech
Fagus sylvatica (European Beech) or Fagus grandifolia (American Beech) • Hardwood
Grain Pattern
Straight to slightly wavy with visible spalting, which creates dark, irregular zone lines caused by fungal activity. The base grain is fine and uniform.
Color Description
Heartwood is typically a pale straw color to medium reddish-brown. The sapwood is creamy white. Exposure to light tends to darken it slightly. The spalting introduces high-contrast dark gray and black streaking.
Hardness Rating
1,300 lbf (Hard)
Durability Rating
Non-durable; susceptible to rot and insect attack, which is why the spalting process (initial stage of decay) is controlled for aesthetic purposes.
Common Uses
Furniture, flooring, cabinetry, decorative veneer, turned objects, bowls, and tool handles.
Geographic Origin
Eastern North America or Europe
Market Value & Sustainability
Estimated Market Value
$8.00 - $15.00 per board foot depending on the intensity of the spalting and board thickness.
Wood Age Estimate
The visible saw marks and surface oxidation suggest it is a rough-cut slab, likely seasoned for 1-3 years since harvest.
Sustainability Status
Least Concern (IUCN); widely available and harvested sustainably in most regions. Not CITES listed.
Workability
Generally works well with both hand and machine tools, though the spalted areas may be softer (punky) and prone to tearout, requiring sharp tools or stabilizers like CA glue.
Notable Features
Features distinct black 'zone lines' (spalting). It has a very high shock resistance and is often used in steam bending applications.
Finish Recommendations
Requires a sealer or wood conditioner due to varying densities in spalted regions. Polyurethane or lacquer are recommended to preserve the color; oil finishes can significantly darken the figure.
Identification Confidence
High. The characteristic black zone lines against a pale, fine-grained background are classic indicators of spalted Beech.
