Burlwood
A burl (American English) or burr (British English) is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. Burl formation is typically a result of some form of stress such as an injury or a viral or fungal infection. Burls yield a very peculiar and highly figured wood sought after in woodworking, and some items may reach high prices on the wood market. Poaching of burl specimens and damaging the trees in the process poses a problem in some areas. Description A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Almost all burl w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marquetry
Marquetry (also spelled as marqueterie; from the French ''marqueter'', to variegate) is the art and craft of applying pieces of veneer to a structure to form decorative patterns, designs or pictures. The technique may be applied to case furniture or even seat furniture, to decorative small objects with smooth, veneerable surfaces or to freestanding pictorial panels appreciated in their own right. Marquetry differs from the more ancient craft of inlay, or intarsia, in which a solid body of one material is cut out to receive sections of another to form the surface pattern. The word derives from a Middle French word meaning "inlaid work". Materials The veneers used are primarily woods, but may include bone, ivory, turtle-shell (conventionally called "tortoiseshell"), mother-of-pearl, pewter, brass or fine metals. Marquetry using colored straw was a specialty of some European spa resorts from the end of the 18th century. Many exotic woods as well as common European varieties ...

Picea Sitchensis
''Picea sitchensis'', the Sitka spruce, is a large, coniferous, evergreen tree growing to almost tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and coast Douglas fir). The Sitka spruce is one of the few species documented to exceed in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California. Description The bark is thin and scaly, flaking off in small, circular plates across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than . The shoots are very pale buff-brown, almost white, and glab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redwood National Park
The Redwood National and State Parks (RNSP) are a complex of one national park and three state parks, cooperatively managed, located in the United States along the coast of northern California. Comprising Redwood National Park (established 1968) and California's State Parks: Del Norte Coast, Jedediah Smith, and Prairie Creek (dating from the 1920s), the combined RNSP contain , and feature old-growth temperate rainforests. Located within Del Norte and Humboldt Counties, the four parks, protect 45 percent of all remaining coast redwood (''Sequoia sempervirens'') old-growth forests, totaling at least . These trees are the tallest, among the oldest, and one of the most massive tree species on Earth. In addition to the redwood forests, the parks preserve other indigenous flora, fauna, grassland prairie, cultural resources, waterways, and of pristine coastline. In 1850, old-growth redwood forest covered more than of the California coast. The northern portion of that area wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beijing Temple Of Confucius
Beijing Temple of Confucius () is the second-largest Confucian temple in China, after the one in Confucius's hometown of Qufu. History The Temple of Confucius in Beijing was built in 1302 during the reign of Temür (Emperor Chengzong) of the Yuan dynasty. The compound was enlarged twice, once during the Ming dynasty and again during the Qing dynasty; it now occupies roughly . Until the Xinhai Revolution, imperial officials of the Yuan, Ming and Qing dynasties hosted ceremonies to pay their formal respects to Confucius in the temple. From 1981 until 2005, the Temple of Confucius also housed part of the art collection of the Capital Museum. It stands on Guozijian Street near the Imperial Academy. Grounds The complex includes four courtyards aligned along a central axis. From south to north, noteworthy structures include the Gate of the Late Master (, ''Xianshimen''), the Gate of Great Accomplishment (, ''Dachengmen''), the Hall of Great Accomplishment (, ''Dachengdian''), and the ...

Olympic National Park
Olympic National Park is a United States national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast. President Theodore Roosevelt originally designated the park as Mount Olympus National Monument on March 2, 1909. The monument was re-designated a national park by Congress and President Franklin D. Roosevelt on June 29, 1938. In 1976, Olympic National Park was designated by UNESCO as an International Biosphere Reserve, and in 1981 as a World Heritage Site. In 1988, Congress designated 95 percent of the park () as the Olympic Wilderness, which was renamed Daniel J. Evans Wilderness in honor of Governor and U.S. Senator Daniel J. Evans in 2017.

Splitting Maul
A splitting maul also known as a ''block buster'', ''block splitter'', ''chop and maul'', ''sledge axe'', ''go-devil'' or ''hamaxe'' is a heavy, long-handled axe used for splitting a piece of wood along its grain. One side of its head is like a sledgehammer, and the other side is like an axe. Tools ; Wedged mauls: A typical wood splitting maul has a head weight of 6 to 8 lb or approximately 2.7 to 3.6 kg, respectively. Traditionally, mauls have a wedge-shaped head, but some modern versions have conical heads or swiveling sub-wedges. The original maul resembles an axe but with a broader head. For splitting wood, this tool is much better than a typical axe. The weight of it is more advantageous, and it is less likely to become stuck in the wood thanks to its width. The wedge section of a maul head must be slightly convex to avoid jamming and it cannot have the elongated "hollow ground" concave-section that a cutting axe may use. Unlike an axe, maul handles are normall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
