Color: Heartwood is
yellow after during 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 Within Species And Grades: Moderate color
Fumed: A process that
involves exposing the wood to ammonia fumes to give wood a rich
hearty tone similar to an antique finish, but more uniform in color and
5% softer than Northern red oak.
Dimensional Stability: Above average (change
coefficient .00263; 29% more stable than red oak).
Durability: Natural resistance to insect infestation
in heartwood; dense.
machining and handtooling qualities.
Sanding: Tendency to clog paper due to high resin
content; begin with coarse grade.
Nailing: Good holding quality.
Finishing: Accepts both surface and penetrating
finishes. Some stains may blotch; raising grain first may help. To
reduce the wood's tendency to repel finish coats, surface resins may be
removed with a solvent that is compatible with the finish to be used
Comments: (Slow-growth longleaf pine, often recovered
from structural timbers in pre-1900 warehouses and factories, or as
sunken logs from river bottoms.
