ASH LUMBER: THE UNSUNG HERO OF HARDWOOD

on December 09, 2025

 

Few hardwoods balance strength, beauty, and workability quite like Ash. With its pale colour, bold grain, and legendary toughness, Ash Lumber has been a quiet favourite among furniture makers, turners, and tool-handle craftsmen for generations.

At The Knotty Lumber Co., we carry Ash Lumber for one simple reason—it consistently performs. Whether you’re building durable furniture, crafting cabinetry, or working on fine turning projects, Ash delivers strength without unnecessary weight.


What Is Ash Lumber?

Ash Lumber comes from the Fraxinus genus, a group of North American hardwoods known for their resilience and clean grain. White Ash (Fraxinus americana) is the most popular species for woodworking thanks to its superior strength and beautiful cathedral grain.

Historically prized for baseball bats, axe handles, and everyday-use furniture, Ash’s combination of impact resistance, elasticity, and clean appearance makes it ideal for both rustic and modern designs.


Ash Lumber Appearance and Colour

Ash’s visual appeal lies in its light, clean, and versatile appearance.

Typical Characteristics:

  • Colour: Light beige to creamy brown, sometimes with a gentle golden tint

  • Grain: Straight, bold, and open with cathedral-like patterns

  • Texture: Medium–coarse, similar to oak but smoother

  • Luster: Natural satin glow that brightens beautifully with finish

Ash accepts stain exceptionally well—allowing it to mimic walnut, oak, or even exotic hardwoods when desired.


Working Properties and Hardness

Ash is a tough wood, but surprisingly cooperative. It machines well and is strong enough for demanding builds.

Technical Overview:

  • Janka Hardness: ~1,320 lbf (similar to Red Oak)

  • Density: Medium-heavy; excellent strength-to-weight ratio

  • Workability: Machines, turns, sands, and finishes easily

  • Gluing & Fasteners: Excellent adhesion and strong fastener hold

  • Bending: High shock resistance; ideal for steam bending

Ash’s open grain may raise slightly after sanding—using a grain filler or pre-sealer helps achieve a smooth, refined finish.


Applications: Versatile and Reliable

Ash is one of the most adaptable hardwoods available, suitable for nearly any interior woodworking project.

Common Uses Include:

  • Furniture & cabinetry

  • Table legs and chair frames

  • Flooring & stair parts

  • Baseball bats & tool handles

  • Turned bowls, pens, and spindle work

  • Veneers & decorative wall panels

If you love the durability of oak but want a brighter, cleaner aesthetic—Ash is your wood.


Advantages of Ash Lumber

  • Exceptional Strength: Withstands heavy use and impact

  • Lightweight Stability: Strong without being overly heavy

  • Bold, Beautiful Grain: Striking cathedral patterns

  • Versatile Finish Options: Takes stain evenly and predictably

  • Sustainable: Responsibly sourced across North America

Ash offers professional-grade performance for everyone—from hand tool purists to CNC woodworkers.


Challenges and Considerations

Ash is beloved, but there are a few things to keep in mind:

  • Open Pores: Grain filler helpful for ultra-smooth finishes

  • Weight: Slightly heavier than maple or cherry

  • Availability: Emerald ash borer has impacted supply in some areas

  • Outdoor Limitation: Not naturally rot-resistant—needs protection outdoors

Still, Ash remains one of the most dependable and visually appealing hardwoods you can buy.


Finishing Ash Lumber

Ash is incredibly finish-friendly. Its open grain readily absorbs oils and stains, making it ideal for both natural and dark-toned finishes.

Recommended Finishes:

  • Clear water-based or poly: Highlights grain while protecting

  • Danish or Tung Oil: Adds warmth and depth

  • Stain: Excellent for colour matching or custom tones

  • Wax: Soft, elegant sheen for indoor furniture

For a high-end look, apply grain filler before finishing to achieve a smooth, glass-like surface.


Ash Lumber vs. Oak Lumber

These two hardwoods are often compared. Here’s how they differ:

Feature Ash Lumber Oak Lumber
Colour Light beige → pale brown Warm brown → reddish tones
Grain Bold, straight, open Coarse, varied, porous
Hardness ~1,320 lbf ~1,290 lbf (Red Oak)
Workability Easy to machine Harder on tools
Finish Even stain acceptance Can blotch/darken
Weight Moderate Heavier
Price Often more affordable Slightly higher

Ash delivers oak-level durability with a lighter, more contemporary look—perfect for Scandinavian or minimalist designs.


Buying Ash Lumber

When selecting Ash, look for:

  • Kiln-dried stock for stability

  • Clean grain and even tone

  • Minimal defects

  • Clear species labeling (“Ash Lumber” or “White Ash”)

Fun Fact: Ash and Baseball’s Golden Age

For more than a century, Louisville Slugger baseball bats were made almost exclusively from White Ash. Its unique blend of lightness and flexibility provided unmatched swing feel—earning Ash a legendary place in baseball history.
