Burl wood is one of the most sought-after materials in the world of woodworking. Known for its chaotic grain patterns, swirling knots, and unique textures, it transforms ordinary furniture and crafts into extraordinary pieces of art. Whether you are a professional furniture maker or a hobbyist turner, finding the right source for burl wood is the first step toward a successful project.
In this guide, we will explore the different types of burl wood available and the best ways to source high-quality slabs, veneers, and blanks. You will learn what to look for when purchasing these materials and how to ensure you are getting the best value for your investment.
What Makes Burl Wood Special?
Burl wood is not a specific species of tree, but rather a growth that occurs on various types of trees. These growths are typically caused by some form of stress, such as injury, virus, or fungal infection. The tree reacts by growing its grain in a twisted, knotted, and irregular fashion.
Because the grain is so unpredictable, burl wood is incredibly dense and visually striking. No two pieces are ever exactly alike. This uniqueness makes it a premium choice for high-end furniture, musical instruments, and decorative accents.
The Visual Appeal of Burl
The main reason woodworkers seek out burl is the “figure.” You might see “eyes,” swirls, or bird’s-eye patterns that are impossible to find in standard lumber. When polished and finished, these patterns take on a three-dimensional depth that is truly captivating.
Choosing the Right Format for Your Project
Before you start searching for a supplier, you need to determine which format of burl wood fits your specific needs. Burl is sold in several different ways, each suited for different applications.
Burl Wood Slabs
Slabs are thick, large cuts of wood often used for tabletops, shelving, or wall art. Because burls are often irregular in shape, these slabs usually feature “live edges,” where the natural exterior of the tree is left intact. Slabs are ideal for those looking to make a bold statement with a large surface area.
Wood Veneers
Burl wood is rare and expensive. Veneers allow woodworkers to cover a larger surface area using a very thin layer of high-quality burl. This is common in cabinetry, automotive interiors, and fine furniture. It provides the look of solid burl without the extreme cost or weight.
Turning Blanks and Pen Blanks
If you enjoy woodturning, you will likely look for turning blanks. These are smaller, chunky blocks of wood used to create bowls, vases, or tool handles. Pen blanks are even smaller, specifically sized for creating custom writing instruments. These are often the most affordable way to start working with burl.
Knife Scales
For knife makers, burl is a favorite for handles. “Scales” are pairs of matched wood pieces that are attached to the tang of a knife. Because burl is dense and durable, it holds up well to the handling and moisture that knives often encounter.
Key Factors to Consider When Buying
Purchasing burl wood is different from buying standard 2x4s at a local hardware store. Because it is a specialty product, you need to pay close attention to the details to avoid wasting money on unusable material.
- Moisture Content: Like all wood, burl must be properly dried. Look for “kiln-dried” wood if you plan to use it immediately. “Green” wood is cheaper but will shrink and potentially crack as it dries in your shop.
- Stability: Due to the irregular grain, burl is prone to cracking and checking. Check if the supplier has stabilized the wood with resins or if there are visible voids that you will need to fill with epoxy.
- Figure Density: Not all burls are created equal. Some have tight, dense patterns throughout, while others might have large areas of plain grain. High-density figure usually commands a higher price.
- Species: Different trees produce different colors and densities. Common favorites include Maple, Walnut, Redwood, and Buckeye.
Where to Find High-Quality Burl Wood
Finding a reliable source is essential for getting quality material. While you might occasionally find burl at a local lumber yard, specialty suppliers are usually your best bet.
Specialty Online Retailers
Many suppliers specialize specifically in exotic and figured woods. These retailers often provide high-resolution photos of the exact piece you are buying. This is crucial for burl because the grain pattern is the most important feature. Look for sellers who list dimensions and moisture content clearly.
Local Sawmills and Artisans
If you live in an area with a lot of timber industry, local sawmills may have burls that they set aside. These are often sold at a lower price than online retail, but you may have to do the drying and processing yourself. Connecting with local woodworking clubs can also lead you to private collectors or small-scale harvesters.
Woodworking Auctions and Classifieds
Online auction sites and woodworking forums are excellent places to find unique pieces. Many hobbyists sell off their extra stock or “shorts” (small pieces) that are perfect for smaller projects. Just be sure to ask about the drying history of the wood before bidding.
Tips for Working With Burl Wood
Once you have sourced your wood, keep in mind that burl requires a different approach than straight-grained lumber. Because the grain goes in every direction, it is prone to “tear-out” when using planers or chisels.
- Use Sharp Tools: Dull blades will catch on the irregular grain and cause chips. Ensure your tools are razor-sharp before you begin.
- Slow Down: Take light passes when machining or sanding. Rushing can lead to deep gouges that are difficult to remove.
- Consider Epoxy: Many burls have natural holes or soft spots. Using a clear or colored epoxy resin can fill these gaps and add structural integrity to the piece.
- Sand Carefully: Burl sands beautifully, but because the density varies across the piece, you should use a backing block to ensure you don’t create uneven spots.
Conclusion
Sourcing and working with burl wood is a rewarding experience that allows you to create truly one-of-a-kind items. By understanding the different formats—from large slabs to small turning blanks—and knowing what to look for in terms of moisture and figure, you can find the perfect piece for your next project. Remember to take your time during the selection process and prioritize suppliers who provide clear information about their stock.
