Color/Appearance: The heartwood is a light brown color, though darker shades can also be seen, which is sometimes sold as Olive Ash. Sapwood can be very wide, and tends to be a beige or light brown; not always clearly or sharply demarcated from heartwood.
Grain/Texture: Has a medium to coarse texture similar to oak. The grain is almost always straight and regular, though sometimes moderately curly or figured boards can be found.
Endgrain: Ring-porous; large earlywood pores 2-4 rows wide, small latewood pores solitary and radial multiples; tyloses common; parenchyma banded (marginal), paratracheal parenchyma around latewood pores vasicentric, winged and confluent; narrow rays, spacing normal.
Rot Resistance: Heartwood is rated as perishable, or only slightly durable in regard to decay. Ash is also not resistant to insect attack.
Workability: Produces good results with hand or machine tools. Responds well to steam bending. Glues, stains, and finishes well.
Odor: Can have a distinct, moderately unpleasant smell when being worked.
Allergies/Toxicity: Ash in the Fraxinus genus has been reported to cause skin irritation, and a decrease in lung function. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Ash is among the least expensive utility hardwoods available domestically; it should compare similarly to oak in terms of price.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Flooring, millwork, boxes/crates, baseball bats, and other turned objects such as tool handles.
Comments: White Ash has fairly good strength properties for its weight, and is also shock resistant.
