Explore the Basics of Sculpture

Throughout history the techniques artists use to create sculptures have been largely determined by available materials and tools as well as by the purpose of the finished work.

This carved ivory statue shows a mostly nude man standing on a square base with his hands bound to one side as he looks over the other shoulder. In this photograph, his wrists are tied together to our right, and he looks off to our left with his face tucked close to that shoulder. He has a curly beard and long wavy hair, which is pushed back over his shoulders. His lips are parted and his brows gathered. Both feet are planted on the base but most of his weight rests on his straight right leg, on our left, and the other knee is bent. This makes his right hip, on our left, jut out as his torso angles to our right. A loincloth drapes around his hips and ties at his right hip, on our left. His torso, arms, and legs are muscled, and veins stand out on his hands and arms. Some cracks are visible along the surface.

Carving: Sculptors use metal tools and abrasives to create figures, reliefs, or abstract forms. They often work with hard materials, such as stone and wood. Carving is considered a subtractive process, which means artists remove material with chisels or other tools to form the sculpture.

Sculpted in clay, a toddler balances his plump body on his right foot as he raises his left leg and right arm. In ths photograph, his body is squared to us. His left hand, on our right, rests near his hip. Gazing up and to our left, his cheeks are puffed in blowing through pursed lips, and his hair falls in soft ringlets. The fingers of his raised hand are folded into a loose fist. Tipped slightly forward onto his toes, he balances on a gold-half dome.

This freestanding, beige, terracotta bust shows the head and shoulders of a cleanshaven man, Giuliano de' Medici, wearing a suit of armor. The bust is straight across the bottom so it rests directly on the white surface on which it is photographed. In this view, the man’s shoulders are square to us, and he looks off to our right, chin lifted. His eyes are blank, and he has a bumped, aquiline nose and rounded cheeks. His lips are closed, the corners slightly pulled back. His thick, curly hair is cut to create an angle down from his eyebrows, on either side of his forehead, to the back of his neck. His breastplate has a high collar, and, at the front center, a man’s head is sculpted in relief with his mouth wide open, head flanked by upswept wings. The yelling man’s teeth and tongue are visible, and he has wavy hair and prominent ears. The pauldrons, the armor covering Giuliano's shoulders, and the rest of the breastplate are decorated geometric shapes and curved lines that end in sharp points.

Modeling: When working with soft materials, such as clay and wax, sculptors use their hands, assisted by tools made of metal, wood, bone, or plastic, to build up forms. Sometimes they use a wood or metal framework (armature) to support the weight of the materials. Artists fire clay in a hot kiln to turn it into durable terracotta.

Severo da Ravenna, Neptune on a Sea Monster, c. 1500/1509, bronze, Widener Collection, 1942.9.104

This free-standing bronze sculpture shows a nude, muscular man sitting on a rock and resting his chin on the back of his right hand, with that elbow propped on his left knee. In this photograph, the man’s body is angled slightly to our left. He hunches a bit as his body twists so his right elbow, on our left, reaches the opposite knee. His other rests along his leg so the hand dangles beyond the knee. The man has short-cropped hair, a furrowed brow, an angular nose, and lines around his mouth and eyes. The foot on our right rests higher on the rock so that knee juts up a little higher than the other. The bronze has a greenish patina, especially noticeable along the top of the man’s head and shoulders and the front of his lower legs.

Molding and casting: Sculptors can create copies of their work through molding and casting. They use plaster, clay, gelatin, or silicone to make a mold of the sculpture, and then they fill the mold with moist clay, plaster, or another material to reproduce it. Some sculptures cast from a mold are considered finished works, while others are used as models for future molds.

Hammering: Sculptors occasionally use a hammer or awl to add details or decorative patterns to a surface. They form a relief sculpture by working a thin section of metal, freehand or around a mold, from the front (embossing) or by pushing forms out from the back (repoussé). Striking, a related method utilized with coins, uses a mold (die) to press a design into metal.

The outline of a fish is made with bent, colored wire and then hung with fragments of colored glass to loosely resemble scales in this free-floating sculpture. In this photograph, the open mouth faces our left. The body is made with a thick gauge, mustard-yellow wire. Finer, gold-colored wire creates a honeycomb-like pattern within the body. Pieces of colored glass hang within most of the cells. The irregularly shaped pieces are clear or in tones of brick red, indigo or sky blue, amber brown, pearl white, or emerald green. A few cells have little bits of metal, including a washer, a disk pierced with holes, and a spiraling piece of wire. The thicker yellow wire makes a circle near the mouth, creating an eye, which is hung with two pieces of glass in plum purple and pale lilac. To our right, the tail is as tall as the body and half its length. It is outlined with thick, red wire. Another piece of wire runs along the middle of the tail, and thinner red wire is strung from the central wire to the upper and lower edges, mimicking the rays of the fish’s fin. A fin along the bottom center of the fish’s body is made with thick, royal-blue wire that balances across the bottom rim of the fish. On the side closer to us, the blue wire is bent into a boomerang shape. It is suspended within a cell close to the bottom of the fish’s body, and is balanced on the far side with a piece of cobalt-blue glass. A hand-shaped pendant hangs from the point of the fin closest to us. The wall behind the hanging sculpture is fog gray.

Assemblage: Artists use the assemblage process to arrange carefully shaped or found objects into a sculpture. The parts of the sculpture might be all of one kind or a variety of elements. Modern sculptors who practice this process bring together found or diverse elements to create a sculpture, that is, a three-dimensional version of a collage. The combination of elements can result in a work of beauty, visual interest, or significant meaning.

Four women, six men, and seven babies and children are gathered in three rows in this freestanding, painted wooden sculpture. The people all have pale, peachy skin with rosy cheeks, round faces with double chins, and thin, curving brows under high foreheads. They mostly wear gold robes over garments in gray, dark blue, plum purple, spruce green, or red. The four women sit hip-to-hip across the middle of the grouping. The two center women angle slightly in toward each other. To our left in that pair, Mary holds a nude baby Jesus on her lap. Mary’s long, loose, light brown hair is held back with a twisted band. The chubby Jesus on her lap reaches for the woman to our right, Saint Anne, who wears a voluminous wimple that covers her face, chin, neck, and shoulders. The women to either side of the central pair hold books, one open and one closed, and wear turban-like headdresses over long, wavy hair. Six children play together in two groups at the women’s feet. Some are nude and others wear dark or gold robes. A pair eat grapes to our left. The right-most child rides a hobby horse and holds onto the hand of the woman behind him with his tiny hand. In the top row, a man stands behind each of the four women except for Saint Anne, who has three men standing over her shoulder. Two of the six men are cleanshaven, and the others have beards. Some are bareheaded and others wear turbans or a cap. Their faces are lined, and they look down or off into the distance, most under furrowed brows. The gold on the robes is tooled to create patterns.

Polychromy: The term polychromy means “many colors.” Applying color to the surface of a sculpture can heighten its sense of energy and bring surfaces to life. Artists use paint, gold leaf, or glaze to direct viewers’ focus and highlight certain features or forms.
