Segmented Turning
Segmented turning, also known as polychromatic turning, is a form of woodturning on a lathe where the initial workpiece is composed of multiple parts glued together. The process involves gluing several pieces of wood to create patterns and visual effects in turned projects. Variation from traditional wood turning In traditional wood turning, the template is a single piece of wood. The size, grain orientation and colors of the wood, will frame how it can be turned into the target object, such as a bowl, platter, or vase. With segmented turning, the size and patterns are limited only by imagination, skill and patience. While the vast majority of segmented turnings are vessels of one sort or another, strictly speaking, any turned object comprising multiple pieces of glued wood could be classified as a segmented turning. Examples include pens, bowls, vases, salt mills, pepper mills, and rolling pins. By cutting and re-assembling pieces after they are turned, unique forms can be crea ...

Woodturning
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a mechanism that can generate a variety of forms. The operator is known as a ''turner'', and the skills needed to use the tools were traditionally known as ''turnery''. In pre-industrial England, these skills were sufficiently difficult to be known as "the mysteries of the turners' guild." The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel posts for architecture; baseball bats, hollow forms such a ...

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, threading 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, 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 ...

Stave (wood)
] A stave is a narrow length of wood with a slightly bevelled edge to form the sides of barrels, tanks, tubs, vats and pipelines, originally handmade by coopers. They have been used in the construction of large holding tanks and penstocks at hydro power developments. They are also used in the construction of certain musical instruments with rounded bodies or backs.

Wood Carving
Wood carving (or woodcarving) is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculpture, sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery. The making of sculpture in wood has been History of wood carving, extremely widely practised, but does not survive undamaged as well as the other main materials like Stone sculpture, stone and bronze, as it is vulnerable to decay, insect damage, and fire. Therefore, it forms an important hidden element in the art history of many cultures. Outdoor wood sculptures do not last long in most parts of the world, so it is still unknown how the totem pole tradition developed. Many of the most important sculptures of China and Japan, in particular, are in wood, and so are th ...

Pyrography
Pyrography or pyrogravure is the free handed art of decorating wood or other materials with burn marks resulting from the controlled application of a heated object such as a Fireplace poker, poker. It is also known as pokerwork or wood burning. The term means "writing with fire", from the Greek (fire) and (writing). It can be practiced using specialized modern pyrography tools, or using a metal implement heated in a fire, or even sunlight concentrated with a magnifying lens (optics), lens. "Pyrography dates from the 17th century and reached its highest standard in the 19th century. In its crude form it is pokerwork." Pyrography is also popular among gourd crafters and artists, where designs are burned onto the exterior of a dried hard-shell gourd. History Pyrographer Robert Boyer hypothesizes that the art form dates back to prehistory when early humans created designs using the charred remains of their fires. It was known in China from the time of the Han dynasty, where ...

Gold Leaf
upA gold nugget of 5 mm (0.2 in) in diameter (bottom) can be expanded through hammering into a gold foil of about 0.5 m2 (5.4 sq ft). The Japan.html" ;"title="Toi gold mine museum, Japan">Toi gold mine museum, Japan. Gold leaf is gold that has been hammered into thin sheets (usually around 0.1 μm thick) by a process known as goldbeating, for use in gilding. Gold leaf is a type of metal leaf, but the term is rarely used when referring to gold leaf. The term ''metal leaf'' is normally used for thin sheets of metal of any color that do not contain any real gold. Gold leaf is available in a wide variety of karats and shades. The most commonly used gold is 22-karat yellow gold. Pure gold is 24 karat. Real, yellow gold leaf is approximately 91.7% pure (i.e. 22-karat) gold. Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years and is still done by hand.

Inlay
Inlay covers a range of techniques in sculpture and the decorative arts for inserting pieces of contrasting, often colored materials into depressions in a base object to form Ornament (art), ornament or pictures that normally are flush with the matrix. A great range of materials have been used both for the base or matrix and for the inlays inserted into it. Inlay is commonly used in the production of decorative furniture, where pieces of colored wood, precious metals or even diamonds are inserted into the surface of the carcass using various matrices including clear coats and varnishes. Inlay (guitar), Lutherie inlays are frequently used as decoration and marking on musical instruments, particularly the smaller String instrument, strings. Perhaps the most famous example of furniture inlay is that of André-Charles Boulle (1642–1732) which is known as Boulle work and evolved in part from inlay produced in Italy during the late 15th century at the ''studiolo'' for Federico da ...

Wood Stain
Wood stain is a type of paint used to colour wood comprising colourants dissolved and/or suspended in a vehicle or solvent. Pigments and/or dyes are largely used as colourants in most stains. The initial application of any paint or varnish is absorbed into the substrate similarly to stains, but the binder from a stain resides mainly below the surface while the pigment remains near the top or at the surface. Description Wood stain is a type of paint used to colour wood. It consists of colourants dissolved and/or suspended in a ''vehicle'' or solvent. Vehicle is the preferred term, as the contents of a stain may not be truly Solution (chemistry), dissolved in the vehicle, but rather suspension (chemistry), suspended, and thus the vehicle may not be a true solvent. The vehicle often may be water, Alcohol (chemistry), alcohol, a petroleum distillate, or a finishing agent such as shellac, lacquer, varnish and polyurethane. Coloured or stained finishes do not typically deeply penetr ...

Painting
Painting is a Visual arts, visual art, which is characterized by the practice of applying paint, pigment, color or other medium to a solid surface (called "matrix" or "Support (art), support"). The medium is commonly applied to the base with a brush. Other implements, such as palette knives, sponges, airbrushes, the artist's fingers, or even a dripping technique that uses gravity may be used. One who produces paintings is called a painter. In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate other materials, in single or multiple form, including sand, clay, paper, cardboard, newspaper, plaster, gold leaf, and even entire objects. Painting is an important form of visual arts, visual art, bringing in elements such as drawing, Composition (visual art ...

Woodworking
Woodworking is the skill of making items from wood, and includes cabinetry, furniture making, wood carving, joinery, carpentry, and woodturning. History Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among the earlliest finds of woodworking are shaped sticks displaying notches from Kalambo Falls in southen Africa, dating to around 476,000 years ago.
