Spalted Beech
Fagus sylvatica or Fagus grandifolia • Hardwood
Grain Pattern
Usually straight with a fine, even texture, but heavily modified by spalt lines and irregular zone lines created by fungal colonization.
Color Description
Pale cream to light brown heartwood with darker, contrasting black and dark brown map-like lines caused by decay. Luster is low to medium.
Hardness Rating
1300 lbf (Hard)
Durability Rating
Non-durable. The spalting process itself is an early stage of decay, making it susceptible to rot if not kept dry.
Common Uses
Turning, decorative bowls, high-end furniture accents, veneers, and jewelry boxes.
Geographic Origin
Europe and North America (native to temperate regions).
Market Value & Sustainability
Estimated Market Value
$10.00 to $20.00 per board foot depending on the intensity of the figure.
Wood Age Estimate
Sample appears to be a modern blank (less than 5 years old) showing significant oxidation and fungal bloom.
Sustainability Status
Least Concern (IUCN); widely available and not CITES listed.
Workability
Generally works well, but spalted areas can be 'punky' or soft, requiring sharp tools or stabilizers like CA glue to prevent tearout.
Notable Features
Distinctive 'spalting' lines; the fungal spores can be an allergen, so a respirator is highly recommended when sanding.
Finish Recommendations
Clear oils or film-finishes like lacquer to highlight the figure; sanding sealer is often necessary due to varying density.
Identification Confidence
Medium-High. The pale base color combined with the specific pattern of dark zone lines is characteristic of spalted beech.
