It is often found in pure stands and prefers to grow in the Rocky mountain soils at elevations of 4500 to 6500 feet (1372 to 1981 m) in the southern regions of its range. Heartwood Color Brown Red White to cream Pale red to pink Both heartwood and sapwood are nearly white to pale yellowish brown in color Sapwood Color White Color not distinct from heartwood Paler than heartwood Grain Even Figure Straight Distinct (figure) Growth rings (figure) Straight Distinct figure Even Clear growth rings (figure) Texture Fine Fine to medium Medium Luster Lustrous Natural Durability Durable Should not be used under high decay hazard conditions without proper protection Non durable Heartwood has very little resistance to decay Prolonged exposure to the weather is reported to turn the wood light gray, with a silvery sheen. Odor Has an odor No specific smell or taste Kiln Schedules UK=K US=T13C4S/T11D3S UK=K US=T11B4/T10B3 Ease of Drying Easy Tree Size Tree height is 20-30 m The tree is described as a handsome ornamental, attaining a height of 50 to 80 feet (15 to 24 m) at maturity Product Sources Wood produced by Red spruce, White spruce (P. glauca), and Black spruce (P. mariana) are very similar in characteristics and are often mixed and marketed without distinction as Eastern spruce. Wood from Red spruce is generally stronger than that from White spruce. Blunting Effect Blunting effect on machining is slight Boring Good (75+ pieces out of 100 will yield good to excellent results) Gluing Easy to glue Very good properties Mortising Good mortising properties Moulding Moulds well (70+ % of pieces will yield good to excellent results) Movement in Service Stable Nailing Holds nails well Nails hold poorly Excellent resistance to splitting in nailing operations Planing Responds fairly well to planing. Resistance to Impregnation Poor response to preservative treatment Heartwood is resistant Heartwood is extremely resistant Response to Hand Tools Difficult to machine Screwing Very good screw holding qualities Excellent screwing properties Turning Good results Veneering Qualities There is slight to moderate drying degrade and the potential for buckles and splits Moderately easy to veneer Painting Satisfactory results The timber takes paint satisfactorily Strength Properties Density (dry weight) = 23-30 lbs/cu. ft. Work to Maximum Load = very low Toughness-Hammer drop (Impact Strength) = very low Shearing strength (parallel to grain) = very low Mor/Bending strength = very low Modulus of Elasticity (stiffness) = very low Max. crushing strength = very low Low Low Low Low Hardness (side grain) = very soft Trength properties are moderate, but stiffness is rated as above average. Bending strength is similar to that of Teak, which is considered to be strong. Compression strength parallel to grain, or maximum crushing strength, is medium. It is lower in this property than Teak. The wood is soft, and surfaces may dent easily. It also does not wear well, and mars easily. Weight is medium. Resin from both Red and Black spruce is the source of spruce gum, predecessor of modern chewing gum. The young leafy twigs of the tree were a source of spruce beer after boiling and adding flavoring and sugar.
