Key ideas in Woodworking with Burls
- Burls are abnormal growths triggered by external stress like injury or viruses
- Prickly or spiked bark texture often indicates 'birdseye' or 'pin' patterns inside
- Burls contain chaotic grain rather than the straight grain found in standard branches
- The more distorted the bark looks compared to the rest of the tree, the more figured the wood inside will be
- True burls have a 'warty' or cauliflower-like cluster appearance
- Maple burls are the primary source of birdseye patterns
- Burls are abnormal growths triggered by external stress
- Healing wounds (callus wood) usually look like smooth 'lips' closing over a hole
- Redwood burls are known for dense, lacey clusters
- Burls often lack a single clear growth direction
- Walnut provides high-contrast, dark swirling grain
- Identifying visual markers of a true burl versus common tree bumps
- Mapping tree species to their iconic internal burl patterns
- Large, solid burls on the main trunk are more valuable than small ones on high branches
- Burls with 'sound' wood (no rot or hollow centers) are worth significantly more
- Accessibility matters; a burl you can safely harvest is worth more than one in a protected or unreachable spot
