Vegetable Ivory
Vegetable ivory or tagua nut is a product made from the very hard white endosperm of the seeds of certain palm trees. Vegetable ivory is named for its resemblance to animal ivory. Species in the genus ''Phytelephas'' (literally "elephant plant"), native to South America, are the most important sources of vegetable ivory. The seeds of the Caroline ivory-nut palm from the Caroline Islands, natangura palm from Solomon Islands and Vanuatu, and the real fan palm, from Sub-Saharan Africa, are also used to produce vegetable ivory. A tagua palm can take up to 15 years to mature. But once it gets to this stage it can go on producing vegetable ivory for up to 100 years. In any given year a tagua palm can produce up to 20 pounds of vegetable ivory. The material is called ''corozo'' or ''corosso'' when used in buttons. Species Some species from which vegetable ivory is harvested are: *''Phytelephas macrocarpa'' (mainly in Peru and Bolivia) *''Phytelephas aequatorialis'' (mainly in E ...

Lombards Museum 1000
The Lombards () or Langobards ( la, Langobardi) were a Germanic peoples, Germanic people who ruled most of the Italian Peninsula from 568 to 774. The medieval Lombard historian Paul the Deacon wrote in the ''History of the Lombards'' (written between 787 and 796) that the Lombards descended from a small tribe called the Winnili,: "From Proto-Germanic language, Proto-Germanic ''wikt:Reconstruction:Proto-Germanic/winnaną, winna-'', meaning "to fight, win" who dwelt in southern Scandinavia (''Scadanan'') before migrating to seek new lands. By the time of the Roman-era - historians wrote of the Lombards in the 1st century AD, as being one of the Suebian peoples, in what is now northern Germany, near the Elbe river. They continued to migrate south. By the end of the fifth century, the Lombards had moved into the area roughly coinciding with modern Austria and Slovakia north of the Danube, where they subdued the Heruls and later fought frequent wars with the Gepids.

Phytelephas Macrocarpa
''Phytelephas macrocarpa'' is a single-stemmed, unarmed, reclining or erect palm from the extreme northern coastal regions of South America, growing to some 12 m tall. It has been introduced and cultivated in tropical regions all over the world. The trunk is about 30 cm across, with prominent leaf scars. The crown is made up of about 30 plume-like leaves or fronds, each about 8 m long, dead leaves being persistent. It is one of some 7 species of palm in the genus ''Phytelephas'', all of which have been exploited for vegetable ivory or tagua from the seed or corozo nut. The closely related '' Ammandra decasperma'' from Colombia, and '' Aphandra natalia'' from Ecuador, are also sources of vegetable ivory, but of inferior quality and therefore not commercially significant. 'Phytelephas macrocarpa' translates to ‘elephant plant’ with 'large fruit', the endosperm of the nut having the texture of elephant ivory, and consisting of large, thick-walled cells of two long-chain polys ...

Sculpture Materials
Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or moulded or cast. Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. However, most ancient sculpture was brightly painted, and this has been lost. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File (tool)
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted.. A rasp is a form of file with distinct, individually cut teeth used for coarsely removing large amounts of material. Files have also been developed with abrasive surfaces, such as natural or synthetic diamond grains or silicon carbide, allowing removal of material that would dull or resist steel files, such as ceramic. History Early filing or rasping has prehistoric roots and grew naturally out of the blending of the twin inspirations of cutting with stone cutting tools (such as hand axes) and abrading using natural abrasives, such as well-suited types of ...

Hacksaw
A hacksaw is a fine-toothed saw, originally and mainly made for cutting metal. The equivalent saw for cutting wood is usually called a bow saw. Most hacksaws are hand saws with a C-shaped walking frame that holds a blade under tension. Such hacksaws have a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vise, hacksaw blades are set to be facing forwards. History While saws for cutting metal had been in use for many years, significant improvements in longevity and efficiency were made in the 1880s by Max Flower-Nash. George N. Clemson, a founder ...

Chess Piece
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either white or black, and it can be one of six types: king, queen, rook, bishop, knight, or pawn. Chess sets generally come with sixteen pieces of each color. Additional pieces, usually an extra queen per color, may be provided for use in promotion. Number of pieces Each player begins with sixteen pieces (but see the subsection below for other usage of the term ''piece''). The pieces that belong to each player are distinguished by color: the lighter colored pieces are referred to as "white" and the player that owns them as "White", whereas the darker colored pieces are referred to as "black" and the player that owns them as "Black". In a standard game, each of the two players begins with the following sixteen pieces: * 1 king * 1 queen * 2 rooks * 2 bishops * 2 knights * 8 pawns Usage of the term ''piece'' The word "piece" has three meanings, depending ...

Knife
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons ( daggers or switchblades), knives for throwing or juggl ...

Dice
Dice (singular die or dice) are small, throwable objects with marked sides that can rest in multiple positions. They are used for generating random values, commonly as part of tabletop games, including dice games, board games, role-playing games, and games of chance. A traditional die is a cube with each of its six faces marked with a different number of dots ( pips) from one to six. When thrown or rolled, the die comes to rest showing a random integer from one to six on its upper surface, with each value being equally likely. Dice may also have polyhedral or irregular shapes, may have faces marked with numerals or symbols instead of pips and may have their numbers carved out from the material of the dice instead of marked on it. Loaded dice are designed to favor some results over others for cheating or entertainment. History Dice have been used since before recorded history, and it is uncertain where they originated. It is theorized that dice developed from the pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rochester, New York
Rochester () is a city in the U.S. state of New York, the seat of Monroe County, and the fourth-most populous in the state after New York City, Buffalo, and Yonkers, with a population of 211,328 at the 2020 United States census. Located in Western New York, the city of Rochester forms the core of a larger metropolitan area with a population of 1 million people, across six counties. The city was one of the United States' first boomtowns, initially due to the fertile Genesee River Valley, which gave rise to numerous flour mills, and then as a manufacturing center, which spurred further rapid population growth. Rochester rose to prominence as the birthplace and home of some of America's most iconic companies, in particular Eastman Kodak, Xerox, and Bausch & Lomb (along with Wegmans, Gannett, Paychex, Western Union, French's, Constellation Brands, Ragú, and others), by which the region became a global center for science, technology, and research and development.

Button
A button is a fastener that joins two pieces of fabric together by slipping through a loop or by sliding through a buttonhole. In modern clothing and fashion design, buttons are commonly made of plastic but also may be made of metal, wood, or seashell. Buttons can also be used on containers such as wallets and bags. Buttons may be sewn onto garments and similar items exclusively for purposes of ornamentation. In the applied arts and craft, a button can be an example of folk art, studio craft, or even a miniature work of art. In archaeology, a button can be a significant artifact. History Buttons and button-like objects used as ornaments or seals rather than fasteners have been discovered in the Indian Indus Valley civilization during its Kot Diji phase (c. 2800–2600 BC), at the Tomb of the Eagles, Scotland (2200-1800 BC), and at Bronze Age sites in China (c. 2000–1500 BC) and Ancient Rome. Buttons made from seashell were used in the Indus Valley Civilization for orn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
