MaterialsAny material that can be shaped in three dimensions can be used sculpturally. Certain materials, by virtue of their structural and properties and their availability, have proved especially suitable. The most important of these are stone, wood, metal, clay, ivory, and plaster. There are also a number of materials of secondary importance and many that have only recently come into use. PrimaryThroughout history, has been the principal material of monumental sculpture. Result from changes brought about in the structure of sedimentary and igneous rocks by extreme pressure or heat.
The most well-known metamorphic rocks used in sculpture are the, which are recrystallized limestones. Italian, the best known, was used by Roman and Renaissance sculptors, especially, and is still widely used. The best-known varieties used by Greek sculptors, with whom marble was more popular than any other stone, are —from which the and its sculpture are made—and.Because stone is extremely heavy and lacks, it is easily fractured if carved too thinly and not properly supported.
Dental restorative materials that are applied to a tooth or teeth while material is pliable and can be adapted, carved, and finished are classified as direct restorations in the laboratory by the dental laboratory technician; they are delivered from the dental laboratory and are ready to try-in and cement.

A massive treatment without projections, as in and sculpture, is therefore usually preferred. Some stones, however, can be treated more freely and openly; marble in particular has been treated by some European sculptors with almost the same freedom as bronze, but such displays of virtuosity are achieved by overcoming rather than submitting to the properties of the material itself. The main source of is elephant; but walrus, hippopotamus, narwhal (an Arctic aquatic animal), and, in Paleolithic times, tusks also were used for sculpture. Ivory is dense, hard, and difficult to work. Its colour is creamy white, which usually yellows with age; and it will take a high polish. A tusk may be sawed into panels for relief carving or into blocks for carving in the round; or the shape of the tusk itself may be used.
The physical properties of the material invite the most delicate, detailed carving, and displays of virtuosity are common.Ivory was used extensively in antiquity in the Middle and Far East and the Mediterranean. An almost unbroken Christian tradition of reaches from and Byzantium to the end of the Middle Ages. Throughout this time, ivory was used mainly in relief, often in conjunction with precious metals, enamels, and precious stones to produce the most splendid effects. Some of its main sculptural uses were for devotional diptychs, portable altars, book covers, retables (raised shelves above altars), caskets, and crucifixes. The, too, is rich in ivories, especially in Germany. A fine tradition of ivory carving also existed in Benin, a former kingdom of.Related to ivory, horn and bone have been used since Paleolithic times for small-scale sculpture.
Reindeer horn and walrus tusks were two of the Eskimo carver’s most important materials. One of the finest of all medieval “ivories” is a carving in, (Victoria and Albert Museum, London).(sulfate of lime) is especially useful for the production of molds, casts, and preliminary models. It was used by and Greek sculptors as a casting medium and is today the most versatile material in the sculptor’s workshop.When mixed with water, plaster will in a short time recrystallize, or set—that is, become hard and inert—and its volume will increase slightly. When set, it is relatively fragile and lacking in character and is therefore of limited use for finished work.
Plaster can be poured as a liquid, modeled directly when of a suitable consistency, or easily carved after it has set. Other materials can be added to it to retard its setting, to increase its hardness or resistance to heat, to change its colour, or to reinforce it.The main sculptural use of plaster in the past was for molding and casting clay models as a stage in the production of cast metal sculpture.
Many sculptors today omit the clay-modeling stage and model directly in plaster. As a material in the casting of concrete and fibreglass sculpture, plaster is widely used. It has great value as a material for reproducing existing sculpture; many museums, for example, use such casts for study purposes.
Structure carved into a cliff in southernStone carving is an activity where pieces of rough natural are shaped by the controlled removal of stone.

Contents.History The earliest known works of representational art are stone carvings. Often marks carved into rock or will survive where painted work will not. Prehistoric such as the may be as old as 800,000 years , and are carved in stones such as and.These earliest examples of the stone carving are the result of hitting or scratching a softer stone with a harder one, although sometimes more resilient materials such as antlers are known to have been used for relatively soft stone. Another early technique was to use an abrasive that was rubbed on the stone to remove the unwanted area.Prior to the discovery of by any culture, all stone carving was carried out by using an technique, following rough hewing of the stone block using hammers.
The reason for this is that, the hardest available metal until steel, is not enough to work any but the softest stone. The Ancient Greeks used the of bronze to trap small granules of, that are naturally occurring on the island of, thus making a very efficient for abrading the stone.The development of made possible stone carving tools, such as chisels, drills and saws made from, that were capable of being and to a state hard enough to cut stone without deforming, while not being so brittle as to shatter. Carving tools have changed little since then.Modern, industrial, large quantity techniques still rely heavily on abrasion to cut and remove stone, although at a significantly faster rate with processes such as and cutting.One modern stone carving technique uses a new process: The technique of applying sudden high temperature to the surface. The expansion of the top surface due to the sudden increase in temperature causes it to break away. On a small scale, torches are used.

On an industrial scale, are used. On a massive scale, carvings such as the carved from the Harney Peak granite of and the in Albany, Georgia are produced using heat torches.Stone sculpture. Late 19th century CE.Carving stone into is an activity older than civilization itself. Sculptures were usually human forms, such as the and the faceless statues of the. Later cultures devised animal, human-animal and abstract forms in stone.
The earliest cultures used abrasive techniques, and modern technology employs pneumatic hammers and other devices. But for most of human history, sculptors used hammer and chisel as the basic tools for carving stone.The process begins with the selection of a stone for carving. Some artists use the stone itself as inspiration; the artist claimed that his job was to free the human form trapped inside the block. Other artists begin with a form already in mind and find a stone to complement their vision. The sculptor may begin by forming a model in clay or wax, sketching the form of the statue on paper or drawing a general outline of the statue on the stone itself.When ready to carve, the artist usually begins by knocking off large portions of unwanted stone. This is the 'roughing out' stage of the sculpting process. For this task they may select a point, which is a long, hefty piece of steel with a point at one end and a broad striking surface at the other.

A pitching tool may also be used at this early stage; which is a wedge-shaped chisel with a broad, flat edge. The pitching tool is useful for splitting the stone and removing large, unwanted chunks. Those two chisels are used in combination with a.Once the general shape of the statue has been determined, the sculptor uses other tools to refine the figure. A toothed chisel or claw chisel has multiple gouging surfaces which create parallel lines in the stone.
These tools are generally used to add texture to the figure. An artist might mark out specific lines by using calipers to measure an area of stone to be addressed, and marking the removal area with pencil, charcoal or chalk. The stone carver generally uses a shallower stroke at this point in the process, usually in combination with a wooden.Eventually the sculptor has changed the stone from a rough block into the general shape of the finished statue. Tools called and are then used to enhance the shape into its final form. A rasp is a flat, steel tool with a coarse surface. The sculptor uses broad, sweeping strokes to remove excess stone as small chips or dust.
A riffler is a smaller variation of the rasp, which can be used to create details such as folds of clothing or locks of hair.The final stage of the carving process is polishing. Sandpaper can be used as a first step in the polishing process, or sand cloth.
Emery, a stone that is harder and rougher than the sculpture media, is also used in the finishing process. This abrading, or wearing away, brings out the color of the stone, reveals patterns in the surface and adds a sheen. Tin and iron oxides are often used to give the stone a highly reflective exterior.Sculptures can be carved via either the direct or the indirect carving method. Indirect carving is a way of carving by using an accurate clay, wax or plaster model, which is then copied with the use of a or proportional dividers or a. The direct carving method is a way of carving in a more intuitive way, without first making an elaborate model.
Sometimes a sketch on paper or a rough clay draft is made.Stone carving considerations. 'Arabic' style carving on ashlar building blocks, ScotlandStone has been used for carving since ancient times for many reasons. Most types of stone are easier to find than metal ores, which have to be mined and smelted. Stone can be dug from the surface and carved with hand tools. Stone is more durable than wood, and carvings in stone last much longer than wooden artifacts.
Stone comes in many varieties and artists have abundant choices in color, quality and relative hardness.Soft stone such as, and can be easily carved with found items such as harder stone or in the case of chalk even the fingernail.and can be worked using abrasives and simple iron tools., and some stone is difficult to carve even with iron or steel tools; usually tipped tools are used, although abrasives still work well.
