History and Origin
The history and origin of spalted maple are as intriguing as the wood's unique patterns. Spalted wood, which includes spalted maple, is not an invention but a discovery. It is not a specific species of wood but a term used for any tree that has begun initial stages of decay, halted by drying out to prevent further decline. The partial decay, known as spalting, leaves dark contrasting lines and streaks in the wood. The term "spalting" has been celebrated in Europe for hundreds of years and is German in origin. It refers specifically to coloring found in wood caused by the presence of one or many fungi, which infiltrate the vascular system of the wood and leave pigmentation there.
Characteristics of Spalted Maple
Spalted maple wood is renowned for its distinctive appearance and characteristics that set it apart from other types of wood. It undergoes a natural decay process caused by fungi, resulting in unique patterns of dark lines and streaks. These patterns are formed as the wood decays and are a key identifying feature of spalted maple, giving it a unique and eye-catching appearance. The colors of spalted maple wood are typically soft and muted, providing a warm and inviting appearance.
While a range of wood species can spalt, sugar maple is most prized due to its often very pronounced designs and lighter colored sapwood. Sugar maple trees can live over 130 years, reaching heights of 80-115 feet, with diameters up to 3 feet. The spalting process starts when one of these trees dies and begins to decay, or when a living tree is stressed and weakened due to natural causes or human interaction.
The Spalting Process
Several types of fungi are involved in the spalting process, each contributing to the wood's unique patterns and colors. Key fungi include Penicillium, Trichoderma, and Ascomycetes. These fungi release enzymes that break down the wood's lignin and cellulose, altering its appearance and texture. The spalting process typically involves several stages, starting with colonization by fungi, often at points of high moisture content or damage in the wood. This is followed by competition among various fungal species for resources, leading to the development of unique patterns and colors. Finally, the fungi release pigments and enzymes, resulting in changes in wood coloration and structure.
Another well-known fungus in spalting is Trametes versicolor, commonly known as turkey tail mushrooms. This fungus can create white pigmentation in spalted wood. Additionally, brown rot fungi like Fistulina hepatica, or beefsteak fungus, are also involved in spalting, particularly common on conifers but can grow among deciduous trees as well.
In summary, the spalting process is an intricate interaction between wood and fungi, leading to the creation of beautiful and unique patterns. This natural artistry, brought about by fungi like Penicillium, Trichoderma, Ascomycetes, Trametes versicolor, and Fistulina hepatica, is what sets spalted maple apart, making it highly sought after for various woodworking projects and artistic endeavors.
