Sitka Spruce
Picea sitchensis • Softwood
Grain Pattern
Straight and very tight growth rings; quarter-sawn orientation is evident from the vertical grain lines and silking figure across the face.
Color Description
Creamy white to light pinkish yellow heartwood; sapwood is nearly white and indistinguishable. It possesses a high natural luster and develops a golden yellow patina over time with light exposure.
Hardness Rating
510 lbf (Soft)
Durability Rating
Non-durable to Slightly Durable; poor resistance to rot and fungal decay when exposed to the elements.
Common Uses
Musical instrument soundboards (guitars, violins, pianos), aircraft components, boat building (masts and spars), crates, and general construction.
Geographic Origin
Northwestern North America (Pacific Coast from Alaska to Northern California).
Market Value & Sustainability
Estimated Market Value
$8.00 to $15.00 per board foot for standard grade; instrument-grade tops can exceed $50.00.
Wood Age Estimate
Relatively young wood (kiln-dried modern stock); the surface shows fresh pencil marks and minimal oxidation, suggesting a recently milled or surfaced board.
Sustainability Status
Not listed in CITES Appendices; categorized as Least Concern by the IUCN, though old-growth harvesting is a subject of environmental concern.
Workability
Easy to work with both hand and machine tools; glues and finishes well. It has a high strength-to-weight ratio but can be prone to splintering if tools are not sharp.
Notable Features
Outstanding acoustic properties and resonant qualities; slight resinous scent when worked; very lightweight with exceptional stiffness.
Finish Recommendations
Lightweight finishes like nitrocellulose lacquer, shellac, or thin water-based polyurethanes are recommended to preserve acoustic properties.
Identification Confidence
High; the tight vertical grain, color, and visible 'silking' are classic indicators of quarter-sawn Spruce, often used for instrument making as indicated by the circular layout mark.
