Formation And Characteristics Of Burls
The formation of burls is a result of various factors. Insect infestation and mold infestation are two common causes. These stressors prompt the tree to protect itself by forming a burl as a defensive mechanism. Burls can vary greatly in size, with some tree species capable of producing large ones. The largest burls have been found in coast redwoods, reaching up to an impressive 26 feet in size.
Burls are highly sought after by furniture makers, artists, and wood sculptors for their unique beauty and rarity. The wood that is yielded from burls is highly figured, meaning it displays intricate patterns and characteristics that are incredibly appealing to woodworking enthusiasts. However, working with burl wood can be challenging due to its twisted and interlocked grain. This makes it prone to chipping and shattering, requiring skill and expertise to handle.
Valuable And Prized Woodworking Material
Despite its challenges, working with burl wood is highly rewarding in woodworking. The dense and resistant nature of burls makes them ideal for crafting bowls, mallets, mauls, and hammering tools. Moreover, burls are frequently utilized in creating veneer panels, inserts, furniture slabs, and even musical instruments.
The rarity and unique patterns found in burl wood contribute to its immense value in the wood market. Their desirability results in burls often fetching high prices when sold by lumber companies or individuals. Regrettably, the demand for burls has given rise to illegal practices, such as poaching ancient redwoods in national parks in the Western United States. Nonetheless, legal means of acquiring burls exist, such as obtaining them from private land cleared for development or through salvage permits from lumber companies.
- Burls are dense and resistant, making them perfect for crafting tools and furniture
- Burl wood’s unique patterns make it highly valuable in the wood market
- Illegal practices, like poaching, threaten the availability of burls
- Legal acquisition methods include obtaining burls from private land or salvage permits from lumber companies
“Working with burl wood offers both challenges and rewards. Its dense and resistant nature lends itself to the creation of durable tools and furniture slabs. The rarity and distinctive patterns of burls make them highly sought-after in the wood market. Unfortunately, illegal practices, such as poaching, jeopardize the availability of burls. However, legal means of acquiring burls, such as obtaining them from private land or through salvage permits, ensure that their usage can continue sustainably.”
Burls And Tree Health
Contrary to popular belief, burls are not harmful to tree health; in fact, they serve as a protective response to environmental injuries. The callus tissue that forms the burl acts as a seal, preventing further damage to the tree. Burls are commonly found around the base of the tree trunk or in areas where branches have broken off. Additionally, they can be found in underground tree tissue called lignotubers.
Moreover, burls store the same genetic material as the tree itself, functioning as a way for trees to clone themselves. Lignotubers, which are larger underground burls, play a vital role in this process. While burls can grow in varying sizes and shapes, it is crucial to note that they are not diseased or contagious. On the contrary, they are valuable anomalies that demonstrate the resilience and adaptability of trees in the face of adversity.
Proper Handling And Removal Of Burls
It is important to handle burls with care and consideration. Cutting open a burl reveals wood with complex and unpredictable grain patterns, which can be appreciated and utilized by woodworkers. However, if the burl is undesirable and needs to be removed, it is essential to understand the proper procedure.
Cutting off a burl creates a wound that the tree cannot seal off effectively. Burls do not possess the same response chemicals as normal branch wood, making it difficult for the tree to close over a cut-off burl. Therefore, if removal is necessary, the entire tree should be removed along with its stump. It is recommended to consult a tree care professional for the evaluation of a burled tree. If possible, the burl can be offered to a fine woodworker who can appreciate and transform it into a beautiful piece of art.
Burls are nature’s hidden masterpieces. They are unique and fascinating growths that add character and wonder to trees. Burls have immense value in woodworking due to the highly figured wood they produce. While they do not harm trees, proper handling and removal procedures should be followed to ensure the tree’s health and longevity. Burls are truly remarkable creations of nature, representing both the resilience and beauty found in the natural world.

Frequently Asked Questions
What is the purpose of a burl?
Burls serve a unique purpose in the world of woodworking. Their irregular and distinct grain patterns make them unsuitable for structural use but highly valued for their aesthetic appeal. Burls are commonly transformed into veneer panels, used as inserts, and crafted into furniture slabs and instruments. In these applications, the intricate patterns of burl wood add a touch of elegance and uniqueness, enhancing the overall beauty and artistic value of the final product.
Why is burl so expensive?
The high cost of burl wood can be attributed to its unique beauty and scarcity. Burl wood only grows when trees develop exterior burls, which are uncommon formations. This scarcity makes it more challenging to find and harvest burl wood compared to other types of wood. Additionally, burl wood’s exquisite patterns and swirling grain make it highly sought after, further driving up its price in the market. The combination of its limited availability and exceptional aesthetic appeal contributes to the higher cost of burl wood.
What causes burl on a tree?
Burls on trees are believed to arise from a disturbance in the tree’s growth hormones, resulting in the formation of abnormal cell clusters. Though the precise source of stress remains elusive, numerous factors have been identified as potential causes. These include pests like insects, as well as the proliferation of bacteria and fungi, mistletoes, and environmental harm, such as freeze damage. Ultimately, it is this disruption in growth hormones that leads to the intriguing formation of burls on trees, showcasing nature’s remarkable ability to adapt and respond to its surroundings.
Is burl a type of wood?
Yes, burl is indeed a type of wood. It is a unique grain characteristic that occurs in various types of trees. When a tree or part of a tree with a burl is harvested, it yields burl wood. The burl itself is a growth on the tree that emerges from unsprouted bud tissue, resulting in large, knobby-looking growths on the base and trunk of the tree. This distinctive wood is highly sought after for its intricate and often beautiful patterns, making it a prized material in woodworking and furniture making.
