Grain: Straight, closed, tight
Variations within species and grades: Color varies considerably from tree to tree.
Hardness/Janka: 1375 (7% harder than northern red oak)
Dimensional stability: Excellent at 2.8, which is 67% more stable than red oak, though actual installations have shown a great deal of movement.
Availability: Readily available
Average and maximum lifespan: 50 years
Sawing/Machining: Good machining qualities
Sanding: Its high resin tends to clog sandpaper, so be prepared to change paper often Hard plating and screening can leave swirls; screening it more that twice might be needed. Knots in this wood are very hard and may cause wave. A 12 by 18 inch oscillating sander as the final screening minimizes the scratch pattern.
Nailing: Splits tongues easily and can be brittle
Finishing: knots may cause drying problems because the sap rises to the top of the knot. Avoid high gloss finishes because the sap will combine with the finish and cause waves. Because of low shrinkage it is customarily used in the green or partially dried condition.

Plant habit and lifestyle: Gymnosperm, may reach a height of 100 ft with diameters around 16 in to 24 in.
short, jointed, and angled covered with small scale-like leaves.
Buds: Scale-like, arranged in six rows along the twigs, in alternating whorls of three.
Flowers: Its woody globular cones can remain on the branches for many years. The male cones are small, 3-6 mm long, and are located at the tips of the twigs. The female cones maturing 18-20 months to 1 and a half in. These cones are long and wide, with six overlapping, thick, woody scales, arranged in two whorls of three.
Fruits: 1 to 8 seeds nest below each scale
Habitat: Tolerant of a wide variety of climates, with temperatures from below freezing degrees to over 104, with greater than a foot of annual rainfall. However it is sensitive to fire so prefers undulating or flat land with sandy soils, or in upland rocky climates that protect themselves from frequent, intense fire.
Special Diagnostic Characteristics: This wood has an aromatic camphor-like odor and feels greasy. Working with it may cause an allergic reaction that irritates the nose and eyes, but the scent goes away quickly while you work with it. It’s very resistant to attack by decay, fungi and insects, including termites. High resistance to marine organisms is also reported. The perfect wood for anyone looking for a product that looks antique or a country motif.
