Color
Heartwood is yellow after cutting and turns deep pinkish tan to warm reddish brown within weeks, due to high resin content. Sapwood remains yellow, with occasional blue-black sap stain.

Grain
Dense, with high figuring. Plainsawn is swirled. Rift- or quartersawn is primarily pinstriped. Curly or burl grain is rare.

Variations
Moderate color variations.

Finishing
May be difficult to stain. To reduce te wood’s tendency to repel finish coats, surface resins may be removed with a 100% pure (not recycled) solvent that is compatible with the finish to be used. Do not use water.

Origin
North America. Often recovered from structural timbers in pre-1900 warehouses and factories, or as sunken logs from river bottoms.
