Since it is a swamp species, it grows naturally in wet places. Heartwood Color Brown Yellow Green/grey Orange Red Dark brown Brown Greenish to greyish Yellow to golden-yellow to orange The brown color is typically darker than in other ashes. Sapwood Color White Yellow Brown Red White to yellow Well defined Paler than heartwood Light brown Different than heartwood The narrow sapwood is described as whitish to light brown in color. Grain Figure Even Burrs (figure) Distinct (figure) Growth rings (figure) Straight Figure shows burrs Distinct figure Clear growth rings (figure) Straight 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 Texture Medium Fine Coarse Coarse Black ash is substantially lighter in weight, and is generally 10 to 12 percent less dense than White ash. Luster Medium Low Non-lustrous Dull Natural Durability Perishable Susceptible to insect attack Resistant to termites Moderately durable Non-durable Resistant to marine borers Non-resistant to powder post beetles Non-resistant to termites Non-resistant to marine borers Non durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Susceptible to attack by fungi Sapwood susceptible to attack by powder post beetles Sapwood susceptible to attack by common furniture beetles Little natural resistance Odor No specific smell or taste 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.
