Maple Burl
Acer saccharum (Sugar Maple) or Acer macrophyllum (Bigleaf Maple) • Hardwood
Grain Pattern
Burl/Swirled. Features highly irregular, contorted grain with numerous small knots, clusters, and bird's-eye-like inclusions creating a dense, marbled figure.
Color Description
Natural light golden-tan to creamy yellow. Heartwood can be reddish-brown. Exhibits good luster and chatoyance; tends to darken slightly to a more amber hue with UV exposure.
Hardness Rating
1,450 lbf (Hard - based on Sugar Maple) or 850 lbf (Medium - if Bigleaf Maple)
Durability Rating
Non-durable. Perishable regarding decay resistance and susceptible to insect attack; intended for indoor or protected use only.
Common Uses
Luxury pens, knife handles, musical instrument veneers, high-end furniture inlays, bowls, and ornamental turning.
Geographic Origin
Northeastern North America (Sugar) or Pacific Coast of North America (Bigleaf).
Market Value & Sustainability
Estimated Market Value
$10.00 to $25.00 per board foot for high-quality burl slabs; often sold by the piece for turning blanks.
Wood Age Estimate
3-10 years as a finished product based on the polished surface and lack of significant oxidation or deep wear.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List. Generally sustainable and widely available.
Workability
Difficult due to wild, multidirectional grain. Prone to tearout during planing or turning; requires very sharp tools. Glues and finishes very well.
Notable Features
High density of dormant buds (burl); can occasionally produce a mild scent during machining. Used frequently in resin stabilization for pen making.
Finish Recommendations
High-gloss CA (Cyanoacrylate) finish is standard for pens to protect the wood and highlight depth. Also takes oils and lacquers exceptionally well.
Identification Confidence
Medium-High. The tight, swirled figure and golden-cream color are classic hallmarks of Maple burl, a preferred material for high-quality turned writing instruments.
