Market Value & Sustainability
Estimated Market Value
$10.00 - $20.00 per board foot depending on density and grade
Wood Age Estimate
Relatively new; less than 2 years based on lack of significant oxidation or surface wear
Sustainability Status
IUCN Red List: Least Concern; widely available and fast-growing; not CITES listed
Workability
Extremely easy to work with sharp hand tools; requires very sharp blades to avoid crushing fibers; glues and sands easily; cannot hold nails or screws well.
Notable Features
Exceptionally lightweight with a high strength-to-weight ratio; feels almost weightless like polystyrene foam; possesses large, open vessels.
Finish Recommendations
Sanding sealer or dope for models; typically absorbs large amounts of finish. Heavy finishes will negate its weight advantages.
Identification Confidence
High; the pale color, distinctively large open pores visible on the surface, and the thin, brittle nature of the edge splinter are characteristic of Ochroma.
