Distribution Overview
Black ash ranges from western Newfoundland west to southeastern Manitoba and eastern North Dakota; south to Iowa; east to southern Indiana, Ohio, and West Virginia; and north from northern Virginia to Delaware and New Jersey. Since it is a swamp species, it grows naturally in wet places.

Heartwood Color

Greenish to greyish
Yellow to golden-yellow to orange

The brown color is typically darker than in other ashes.

Sapwood Color

Paler than heartwood
Light brown
Different than heartwood

The narrow sapwood is described as whitish to light brown in color.

Tangential cut boards are reported to exhibit a very distinct figure because of the closely spaced annual rings. Black ash also sometimes exhibit a cluster of eyes, which are occasionally scattered. The wood also produces burls of high quality

Kiln Schedules
T8-D4 (4/4), T5-D3 (8/4) US/T8-D4 (4/4), T5-D3 (8/4) US


Drying Defects
Splitting
Shakes may become extended
End splitting
Distortion (twist/warp) is likely


Ease of Drying
Moderately Difficult to Difficult
Easy

Black ash dries easily with minimum defects, although it is often higher in stump moisture content than other ashes.

Tree Size
Tree height is 20-30 m
Tree height is 30-40 m
Tree height is 10-20 m
Trunk diameter is 100-150 cm
Bole length is 10-20 m
Bole length is 20-30 m


The mature tree is normally 30 to 50 feet (9 to 15 m) in height. Black ash under favorable conditions can attain heights of 90 feet (27 m). Trunk diameters are reported to rarely exceed 24 inches (60 cm)

Product Sources
Although the growth range of Black ash is less extensive than that of White or Green ash, it bes available in adequate supplies. It be often mixed and sold with other ashes under the trade name Ash, and is harder to find through normal retail channels. Price be in the same range as other ash species, moderate to low.

Substitutes
Sassafras (Sassafras albidum) is similar in appearance.

Comments
Black ash is described as a very nice cabinet wood. Although it is softer than the other ashes, it still has enough qualities to allow its use chairs, tables, and other heavily used furniture. White ash is a better selection for applications where strength is important, such as for axe handles. Resistance to abrasion is also rather low in Black ash since the porous earlywood tends to break down or wear away quickly.

General finishing qualities are rated as good

Blunting Effect
Blunting effect on machining is moderate


Boring
Good (75+ pieces out of 100 will yield good to excellent results)


Gluing
Fairly Easy to Very Easy
Satisfactory gluing properties
Moderate gluing properties
Easy to glue


Mortising
Difficult to mortise


Movement in Service
Stable
Small

Properly seasoned wood is dimensionally stable, and shows only small movement in normal use.

Nailing
Fairly Difficult to Very Difficult
Pre-boring recommended
Possible if prebored
Holds nails well


Planing
Fair planing properties

Black ash is comparatively softer and easier to work than the other ashes.

Resistance to Impregnation
Sapwood is permeable
Heartwood is permeable
Heartwood is moderately resistant


Resistance to Splitting
Poor


Response to Hand Tools
Easy to Work
Easy to machine


Sanding
Sanding is fairly difficult


Screwing
Possible if prebored


Turning
Difficult to turn


Veneering Qualities
No drying degrade. Dries flat without splitting
Moderately easy to veneer


Steam Bending
Very good
Good

Black ash is one of the best woods for steam bending.

Polishing
Very Good to Excellent Results
Fair to Good Results
Good results


Staining
Stains well


Varnishing
The natural gray-brown color of the wood is easily enhanced by a few coats of clear varnish.
