Spalted Tamarind
Tamarindus indica • Exotic/Tropical Hardwood
Grain Pattern
Irregular and interlocked grain with dramatic spalting featuring thick, black zone lines (fungal discoloration) creating map-like patterns.
Color Description
Golden yellow to pale brown heartwood with distinct black or dark brown streaks and lines. Moderate natural luster; color may deepen to a more amber tone with age.
Hardness Rating
2,690 lbf (Extremely Hard)
Durability Rating
Non-durable to Slightly Durable; highly susceptible to rot and insects in its natural state, which is why spalting is prevalent.
Common Uses
Turned objects (bowls, pens), knife handles, furniture accents, veneer, and small ornamental items.
Geographic Origin
Native to Tropical Africa; widely cultivated and naturalized in Southeast Asia and South Asia.
Market Value & Sustainability
Estimated Market Value
$15.00 to $30.00 USD per board foot depending on figure intensity.
Wood Age Estimate
Modern sample; appears to be a stabilized wood blank for pen turning or small crafts, possibly less than 5 years since harvesting.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely cultivated as a fruit tree and generally sustainable.
Workability
Difficult due to high density and interlocked grain. Spalting creates soft/punky areas that require sharp tools or stabilization (CA glue/resin) to prevent tearout.
Notable Features
Features iconic black fungal 'zone lines'. The sawdust can be a sensitizer/irritant; the wood is very heavy and lacks a distinctive scent.
Finish Recommendations
Sanding sealer or CA glue finish is best for stabilization. Clear lacquer or polyurethane highlights the black zone lines beautifully.
Identification Confidence
High; the distinctive high-contrast black spalting lines on a golden-yellow substrate are characteristic of Tamarind blanks used in turning.
