Black Oak (Quercus velutina)
Quercus velutina • Hardwood
Grain Pattern
Coarse, straight grain with prominent, wide rays visible in the end grain and cathedral patterns on flat-sawn surfaces. Ring-porous structure is evident in the rough-cut section.
Color Description
Heartwood is light to medium reddish-brown. Sapwood is thin and light tan to white. The wood darkens slightly with age to a more golden brown. Low luster when unfinished.
Hardness Rating
1210 lbf (Hard)
Durability Rating
Non-durable; low resistance to decay and highly susceptible to insect attack if left outside. Rapidly deteriorates in contact with ground moisture.
Common Uses
Flooring, furniture, interior trim, cabinetry, firewood, and barrel staves (non-liquid tight).
Geographic Origin
Eastern North America, ranging from Southern Ontario/Maine to Florida and west to Texas/Nebraska.
Market Value & Sustainability
Estimated Market Value
$2.50 - $4.50 per board foot (Rough Sawn)
Wood Age Estimate
Freshly cut green wood, likely harvested within the last 1-4 weeks based on moisture content and lack of significant oxidation on the sapwood.
Sustainability Status
Least Concern (IUCN), not CITES listed. Widely available and generally sustainable throughout its natural range.
Workability
Easy to machine and cut; however, the high shrinkage rate can cause significant warping or checking during drying. Responds well to steam bending and glues/finishes effectively.
Notable Features
Inner bark is uniquely yellow or orange and contains quercitron (a yellow dye). High tannin content can cause dark stains if in contact with iron and water.
Finish Recommendations
Penetrating oils or polyurethane work best. Large pores may require a grain filler for a glass-smooth finish.
Identification Confidence
High; the blocky 'alligator skin' bark texture, presence of lichen, distinct ring-porous transition, and wide medullary rays are classic indicators of the Red Oak group, specifically Quercus velutina.
