Lumber species of the month... Spruce
Characteristics.... Spruce ranges from near-white to a pale yellow brown, with very little distinction between sapwood and heartwood. It is typically straight-grained, with a fine texture and a natural luster. The contrast between the lighter earlywood and darker latewood makes the growth rings clearly visible. Quarter sawn surfaces occasionally show an attractive ripple figure known as 'flower grain' or Haselichte.
Durability....The wood is not durable, with little resistance to attack from decay-causing fungi, longhorn and pinhole borers and wood wasps. The sapwood is vulnerable to attack from common furniture beetle. The heartwood is resistant to preservative treatment.
Properties... The wood has low resistance to shock loads and low stiffness, medium crushing and bending strength, and very poor steam-bending properties. It works easily and well with both machine and hand tools and has a slightly blunting effect, but hard knots can damage cutting edges. The fifth person who can tell me the origin of this species will get a free bowl blank. Call 513 295 4149.
