Ash (wood)

Description

Any of several hardwood ash trees from the family Oleaceae, genus Fraxinus. Ash trees are widespread throughout the temperate regions of North America (white ash-F. americana; black ash-F. nigra; green ash-F. pennsylvania), Europe (common ash-F. excelsior) and Asia (Japanese ash-F. mandschurica; Chinese ash-F. chinensis). Ash trees produce distinctive growth rings with very large open pores followed by small, tight pores. The light-color, dense, elastic wood has a straight grain that is moderately durable but susceptible to insect attack and moisture degradation. The tough, heavy timber is used for ladders, tool handles, oars, poles, gymnasium equipment and hockey sticks because it produces a smooth surface that rarely splinters. Ash was also popular for furniture (especially colonial pieces), wheels, and carriage frames.
