Ash burl wood is swirling, dense, and alive with movement. It exists at the intersection of ecological accident and extraordinary beauty. And it is disappearing.
At Andrew Pearce Bowls we have the opportunity to work with some of the most exceptional burl wood in New England. As ash trees succumb to the Emerald Ash Borer these this material is becoming ever more rare.
What Is Ash Burl Wood?
Burl forms when a tree experiences prolonged stress, disease, or injury, triggering an abnormal growth response. The result is a dense, rounded mass of compressed wood fibers and tightly clustered dormant buds.
In ash burl specifically, this growth pattern produces some of the most complex visual movement found in any North American hardwood. No two pieces share the same figure as the grain spirals, pools, and folds back on itself.
That irregularity is exactly what makes it irreplaceable. Learn more about the hidden beauty of burl wood.
Why Ash Wood Is Disappearing
The Emerald Ash Borer Crisis
Since its accidental introduction to North America in the early 2000s, the emerald ash borer has killed hundreds of millions of ash trees across the United States and Canada. The insect's larvae feed beneath the bark, cutting off the tree's ability to transport water and nutrients.
The result is catastrophic. Entire ash populations have been eliminated from regions where the species was once abundant. Ash burl, which requires decades to form, is increasingly difficult to source.
What Makes Ash Burl Visually Distinct
Hold an ash burl bowl in direct light and the surface comes alive. Chatoyance, the visible depth and shimmer that shifts as the piece moves, runs through the wood.
The colors range from warm honey and amber to deeper, richer browns depending on the specific tree and finish. Finished with care, the surface achieves a depth that flat-grain wood simply cannot match.
Each bowl is a single, unrepeatable cross-section of a material that no longer forms in abundance.
Is Ash Burl Rare? Understanding Its True Scarcity
Ash burl is rare on two levels. First, burl formation in any species is uncommon. Only a fraction of any tree population develops true burl growth, and even fewer produce pieces large and sound enough to work.
Second, the underlying ash population is in crisis. Combined, these factors mean workable ash burl is among the most limited hardwood materials available to American craftspeople today.
The window for responsibly sourcing this wood is narrowing with each passing season.
How We Work With Rare Wood at Andrew Pearce Bowls
We source ash burl through established relationships with regional foresters in Vermont and the surrounding Northeast. The material we use is carefully selected: structurally sound hardwood with exceptional character and visual interest.
When we turn an ash burl piece, we work to honor the grain rather than override it. The form follows the wood. Our role is to reveal what's already there.
Ash burl bowls are produced in limited numbers and available only as long as our current stock allows. When the material is gone, it is gone.

Ash Burl as Heirloom and Collector Piece
An ash burl bowl is more than a decorative object in the conventional sense. It is an artifact of a particular tree, a particular region, and a particular moment in the ecological history of North American hardwood.
Collectors and design-minded buyers are drawn to burl pieces for exactly this reason. The piece on your table has no equivalent. It cannot be reordered or reproduced.
Displayed as a sculptural object and passed forward as a family heirloom, ash burl ages with a quality that only deepens with time.
The Responsibility of Working With Disappearing Materials
We don't romanticize scarcity, but we do take it seriously. Working with ash burl means accepting that the material is finite and that how we use it matters. We keep production quantities low, process each piece with the attention it deserves, and are transparent with our customers about availability.
The ash burl pieces we make today represent a narrowing window. They are, in a quiet way, a record of what the American hardwood landscape once produced in abundance.

Frequently Asked Questions
What is ash burl wood?
Ash burl is an abnormal, dense wood growth that forms on ash trees in response to stress or injury. It produces tightly compressed, irregular grain patterns that create exceptional visual depth and figure. No two pieces are identical.
Why is ash wood disappearing?
The emerald ash borer, an invasive beetle introduced to North America in the early 2000s, has killed hundreds of millions of ash trees. All major North American ash species are now considered critically endangered or vulnerable by conservation organizations.
Is ash burl rare?
Yes, on two counts. Burl formation occurs in only a small fraction of any tree population. Combined with the widespread loss of ash trees due to the emerald ash borer, workable ash burl is among the scarcest hardwood materials available in North America today.
What makes burl wood valuable?
Burl's value comes from its visual uniqueness, structural density, and the fact that it cannot be cultivated or replicated. Each piece reflects a one-of-a-kind grain pattern formed over decades. In ash specifically, ongoing species decline adds a layer of material scarcity that increases significance over time.
How does Andrew Pearce Bowls source ash burl responsibly?
We work with regional foresters and salvage networks in Vermont and the Northeast to source ash burl from trees that are already compromised or down. We do not harvest speculatively. Availability is limited to existing stock.
Do ash burl bowls hold long-term value?
Ash burl bowls are finite objects made from a disappearing material. Because the underlying wood supply continues to decline and each piece is individually unique, they represent a category of handcrafted object that appreciates in both personal and cultural significance with time.
Andrew Pearce Bowls handcrafts wooden bowls in Vermont from solid American hardwood. Ash burl pieces are available in limited quantities. Browse current availability in our burl collection.
