Striped markings refer to straight-grain wood species like Korean pine, larch, eucalyptus, and jujube. These woods have a consistent grain pattern aligned with the longitudinal axis of the trunk, without any deviation or irregularity.
Staggered markings occur when the grain direction appears in a cyclical rotation, creating an offset effect. This is commonly seen in woods such as citron, madong, big leafhopper, and peach wood, where the grain shifts left and right across the surface.
Waves and stripes are characterized by regularly curved long cells that alternate to the left and right. These patterns give the wood a wavy or striped appearance and are found in species like cherry, maple, birch, Angola rosewood, merbau, and ground wax.
The "back of the piano" pattern, also known as the "Gao" pattern, features raised ridges on the surface when the wood is cut into veneer or panels. This is typical of maple, birch, and peach wood, where the grain creates a textured, bumpy look.
Floc-like markings are formed by interlaced fiber depressions surrounded by irregular patterns. The horizontal grain is more prominent than the vertical, giving the wood a unique texture. Maple and birch often display this kind of pattern.
Black-eyed markings occur when the wood fibers are distorted, creating small conical dents in the growth rings. When cut into veneer, these dents appear as small, twisted shapes resembling "black eyes," especially in maple, birch, and chicken account wood.
Tree-knot markings are common in hardwoods and include feathery lines, fishbone patterns, and fountain-like designs. These natural knots are often used for high-end decorative applications, particularly in black walnut and peach wood.
Silver-light streaks refer to reflective patterns on the wood surface, including horizontal stripes, flakes, ribbons, blocks, or irregular rays. These patterns create a sparkling and glossy effect, commonly found in eucalyptus, Cyclobalanopsis, Longan, Sapphire, Solo, Platanus, South China Wood, Silver Birch, and Holly.
Conical markings are created when the wood has pronounced growth patterns that form beautiful cone-like shapes. Species like gray walnut, red bean tree, and iron knife wood exhibit this distinctive feature.
Parabolic markings result from a rapid transition between early and late wood, causing differences in density. On the tangential cut, this creates a parabolic shape, often seen in ash, eucalyptus, and similar species.
Diagonal flower conical markings are achieved by rotary cutting the wood at a specific angle, typically 45 degrees, to create a visually appealing pattern. This technique is popular in black walnut and other premium hardwoods abroad.
Color stripe markings are patterns formed by unevenly distributed color bands within the wood. These are created when logs are sawn in different ways, and the colors come from pigments and lignin. Examples include walnut (with dark brown heartwood and purple stripes), citron (purple heartwood), and scented rosewood (red heartwood with black stripes).
