Heart Pine (Antique) Species Information
Top portion is finished with water-base urethane; bottom with
oil-modified polyurethane.
Appearance
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 within species and grades: Moderate color
variation.
Properties
Hardness (Janka): 1225; 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.
Workability
Sawing/Machining: Good machining and hand-tooling qualities.
Sanding: Tendency to clog paper due to high resin content;
begin with coarse grade.
Nailing: Good holding ability.
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.
