Reclaimed oak is largely sourced from barn timbers – from smaller dimensional boards that may have clad the structure or its interior division to the largest framing timbers. So the surface tones and textures may be varied, determined by its exposures to light and the life of the barn. The interior surface features are also subject to its time, often over a century, within open country structures. Checks, knots, nail holes and discolorations appear in varied degrees on the scale of light to medium brown tones and open grain of oak. One variation of oak is less apparent, in that the species are more varied than any other source, with a number of apparent old growth oak trees within the broad red and white families.
