White Oak

Grain is usually straight, but can be irregular. Has a medium to coarse texture. Heartwood tends to be darker than temperate walnut species, with a deep chocolate brown color, sometimes with a purplish hue. Peruvian Walnut is rated as moderately durable in terms of decay resistance, though it is susceptible to insect attack. Typically easy to work provided the grain is straight and regular.

Straight, interlocked, irregular or wavy grain. Medium and uniform texture. Hearwood color can vary from pale pinkish brown to darker reddish brown. Color darkens with age. Rot resistance varies on density and growing conditions of the tree. Heartwood is generally resistant to termites, but not other insects. Easy to work with both hand and machine tools, except when working with figured or irregular grain. Sands, turns, glues, stains and finishes well.

Grain is straight, with a very coarse texture. Heartwood is medium brown, sometimes with a reddish or yellowish hue, with nearly black streaks. Upon application of a wood finish (particularly an oil finish) the wood can become nearly black. However, unlike most other dark hardwoods, the heartwood of wenge can lighten (rather than darken) when exposed to sunlight. Very durable; good termite resistance.
