Sitka Spruce
Picea sitchensis • Softwood
Grain Pattern
Straight, fine, and even texture. This sample is vertical grain (quarter-sawn) showing tight, parallel growth rings often preferred for acoustic stability.
Color Description
Heartwood is typically a creamy white to light pinkish-yellow; sapwood is not clearly demarcated from heartwood. It possesses a silky luster and develops a golden-brown patina with age and UV exposure.
Hardness Rating
510 lbf (Soft)
Durability Rating
Slightly durable/Non-durable; low resistance to rot and insect attack if exposed to moisture/ground contact.
Common Uses
Musical instrument soundboards (guitars, pianos), aircraft components, ship masts, ladders, and general millwork where a high strength-to-weight ratio is required.
Geographic Origin
Northwestern Coast of North America, from Northern California to Alaska.
Market Value & Sustainability
Estimated Market Value
$10.00 - $25.00 per board foot for instrument-grade vertical grain material.
Wood Age Estimate
The yellowing/oxidized patina and surface wear suggest this is a secondary-use piece or an older instrument component, likely 20-40 years old.
Sustainability Status
Least Concern (IUCN); widely available as FSC certified; however, old-growth timber is increasingly restricted.
Workability
Generally easy to work with hand and machine tools, though it can be prone to splintering. It glues and finishes well but requires a sealer or toner to avoid blotchy staining.
Notable Features
Highest strength-to-weight ratio of any wood species in the world; outstanding acoustic properties (high velocity of sound); mild resins scent.
Finish Recommendations
Thin coats of nitrocellulose lacquer or spirit varnish are traditional for preserving acoustic properties; polyurethane for utilitarian use. Always use a sanding sealer.
Identification Confidence
High; the combination of extremely tight vertical grain, light color, and characteristic mechanical indentations is typical of Sitka Spruce soundboard material.
