Heartwood is a light to medium brown, commonly with an olive cast. Nearly white to light brown sapwood is not always sharply demarcated from the heartwood. Quartersawn sections display prominent ray fleck patterns. Conversely, Red Oak tends to be slightly redder, but is by no means a reliable method of determining the type of oak. Grain is straight, with a coarse, uneven texture. Produces good results with hand and machine tools. Has moderately high shrinkage values, resulting in mediocre dimensional stability, especially in flatsawn boards. Can react with iron (particularly when wet) and cause staining and discoloration. Responds well to steam-bending. Glues, stains, and finishes well.
