Irish harp
MFA# 17.1788


The hard, fibrous tissue composing the trunk, branches, and roots of trees and shrubs. Wood is a renewable resource that is abundantly available and versatile in its usefulness. It has been used for tools, structures, and as an art material since earliest times. Wood is primarily composed of cellulose (40-60% ), hemicelluloses (15-25%), lignin (15-40%). It can also contain resins, dyes, tannins, waxes, and oils. Wood is still used throughout the world for lumber, furniture, paper, pulp, and fuel. Over 3000 species of trees produce wood. They are categorized as either hardwood (angiosperm) or softwood (gymnosperm) trees. Identification and characterization of wood are based on the following properties (Gettens and Stout 1966):

  • Color of heartwood (interior mature wood) and sapwood (outer actively growing wood).
  • Visibility and size of growth rings
  • Cell size and variation for spring wood (formed at the beginning of the growing season) and summerwood (formed at the end of the growing season).
  • Size and number of medullary rays
  • Pore size and distribution.

Examples of various woods include: Beech, Cedar wood, Chestnut, Fir, Larch, Linden, Mahogany, Maple, Oak, Olive, Pine, Poplar, Walnut, and Willow.
