Spalted Tamarind
Tamarindus indica • Exotic/Tropical Hardwood
Grain Pattern
Generally wavy or interlocked with prominent spalted patterns (black or white lines and mottled patches) caused by fungi. The texture is uniform and medium-to-fine.
Color Description
The heartwood is typically a bold yellowish-brown, sometimes with a red tint. The sapwood is wide and pale yellow. This sample shows high-contrast spalting with pale, bleached zones against a darker base.
Hardness Rating
2,690 lbf (Extremely Hard)
Durability Rating
The heartwood is durable to very durable regarding decay resistance, though the sapwood is susceptible to insect attack. Spalted sections are softer and less durable due to fungal degradation.
Common Uses
Turning blanks, knife handles, inlay, small decorative specialty items, furniture accents, and veneer.
Geographic Origin
Native to tropical Africa; widely cultivated in Southeast Asia, India, and Northern Australia.
Market Value & Sustainability
Estimated Market Value
$15.00 - $35.00 per board foot depending on the intensity of the spalting and figure.
Wood Age Estimate
The sample appears to be modern kiln-dried stock, likely processed within the last 2-5 years given the lack of deep oxidation or mechanical wear.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List of Threatened Species; generally considered sustainable as it is widely cultivated for fruit.
Workability
Difficult due to high density and interlocked grain. Spalted areas can be 'punky' and may require stabilizers (like CA glue or resin) during turning or sanding to prevent tearout.
Notable Features
Known for its 'marble-like' appearance when spalted. It is extremely heavy and dense. Dust can be a respiratory irritant for some woodworkers.
Finish Recommendations
Takes finishes well. High-gloss finishes like CA glue (for small items) or lacquer highlight the chatoyance and spalting lines. Stabilizing with resin is recommended for highly spalted pieces.
Identification Confidence
High. The distinctive high-contrast 'blotchy' spalting and yellowish-tan base color are characteristic of Tamarind turning blanks.
