Some wood species develop distinctive figures and wood patterns during their growth. These natural irregularities make wood veneer popular with furniture makers, interior builders and restorers. Well-known examples are burl veneer , bird's-eye maple , pommelé, rippled maple and quilted maple.
Patterns in wood arise for a variety of reasons, such as the wood fibers themselves, genetic mutation, disease, stress or simply chance . After all, nature follows its own course.
Sometimes you will see unusual patterns, for example where two branches meet. This creates a flower or pyramid motif such as with pyramid mahogany.
Burls are rounded lumps that often form from a wound or insect infestation. When you cut these open, you see intricate patterns that run in every direction. Also check out our burl veneer .
Other processes, such as genetic mutation, can create curly, twisted, blister, quilted, spotted and bird's-eye patterns.
Often these types of patterns are limited to just a small number of wood species.
Another type of pattern forms when a tree grows on a hillside or partially topples over but continues to grow. This causes compression of the wood grain on the underside of the trunk and stretching on the upper side.
Many unusual patterns in veneer, such as pommelé or riegel (rippled veneer) are caused by light reflection, otherwise known as the chatoyance effect (cat's eye effect).
Wood with distinctive patterns is rare and valuable. Particularly with burl veneer, the wood grain often grows in multiple directions at once. If the wood is not properly treated, it can split during drying and later expansion and contraction due to seasonal changes. One way to prevent splitting is to first cut or saw this wood into thin veneer sheets.
Veneer is naturally more stable than thicker solid wood. Veneer also offers a different approach to managing wood movement, which provides more freedom in design. When thin veneer layers are securely bonded to a stable base (called a substrate or backing board), almost all cross-grain movement is prevent
