GENERAL DATA FOR TYPICAL REGIONAL SPRUCE / WHITE WOOD.
Heartwood Color varies from white to pale yellow-brownish color, with very little or no discernible difference between sapwood and heartwood. The wood is typically straight grained. Growth rings are reported to be visible because of the contrast between the darker outer late wood and the lighter early wood. The wood is fine-textured. The material is reported to possess a natural luster. The wood is reported to dry rapidly and well, but requires some care to minimize defects.
There is little tendency for the wood to check and split during drying. Knots may split and loosen, and material with pronounced spiral grain may distort.The wood is reported to have very little natural resistance against attack by decay causing fungi. It is vulnerable to attack by longhorn and pinhole borer beetles, and by wood wasps. The sapwood is susceptible to attack by the common furniture beetle.The timber is reported to respond poorly to preservative treatment. The tree produces resin. Resin exuded through the bark of the tree is called Burgundy pitch, and is reported to have been used to produce plasters.Knotty wood is reported to require sharp cutting edges for best results, because tear may occur around knots in planning. Clear stock works easily with both hand and machine tools in planning, turning, boring, molding, and in most wood working operations to produce smooth and clean surfaces. The wood is reported to glue well. Polishing properties are reported to be good. The material is reported to have good staining characteristics. Varnishing properties are rated as good. The wood is reported to take paint well.Steam bending characteristics are rated as very poor. Strength properties are reported to vary widely and are dependent upon origin. It has medium bending strength in the air-dry condition (about 12 % moisture content). It is closer in strength to Mahogany than either Teak or White oak. It is weak in compression parallel to grain (maximum crushing strength).The wood is soft, and surfaces may dent easily. It also does not wear well and mars easily. Wood is low in weight and has average or medium density.
