Ceramics is art made from clay and fired at high temperatures. From Jomon pottery to contemporary sculpture, learn its history, materials, and methods.
Take a lump of clay, press your thumb into it, and you have begun a practice that is at least 28,000 years old. The clay responds to your hand with a directness that no other material offers. It records every fingerprint, every pressure point, every hesitation. Shape it into a vessel, dry it, and fire it in a kiln, and the soft, temporary form becomes permanent. The clay you held has turned to stone. That transformation, from plastic earth to durable object through the application of heat, is the foundation of all ceramics.
Ceramics is the art and practice of creating objects from clay and permanently hardening them through firing at high temperatures. The term encompasses pottery (functional vessels), sculptural ceramics (non-functional art objects), and architectural ceramics (tiles, bricks, and structural elements). The field ranges from the most ancient functional crafts to contemporary fine art, and the boundary between craft and art in ceramics has been contested for over a century. The materials include earthenware, stoneware, and porcelain, each defined by clay composition and firing temperature. The processes include hand-building (pinching, coiling, slab construction), wheel-throwing, molding, and glazing.
This entry covers what ceramics is, how the materials and processes work, where ceramics sits in art history, which artists defined the medium, and how the field is evolving today.
Ceramics begins with clay, a naturally occurring material composed of fine-grained minerals, primarily hydrous aluminum silicates, that becomes plastic when mixed with water. Plasticity is the key property: wet clay can be shaped, and it holds that shape until it dries or is fired. When clay dries, the water evaporates and the particles bind together through a process called leather-hardening. The object is now fragile but can be handled, carved, and decorated. When clay is fired in a kiln at temperatures between 600 and 1,400 degrees Celsius, the mineral particles undergo chemical changes that permanently transform the material. At low temperatures, the clay becomes earthenware, porous and relatively soft. At higher temperatures, the clay vitrifies, meaning the minerals partially melt and fuse together, producing a denser, less porous, and more durable material.
The three main ceramic bodies are defined by their composition and firing temperature. Earthenware is fired between 900 and 1,100 degrees Celsius. It remains porous after firing, which means it must be glazed to hold liquids. Terracotta (Italian for "baked earth") is a type of earthenware, typically red-brown from iron oxide content. Stoneware is fired between 1,200 and 1,300 degrees Celsius. It vitrifies partially, becoming dense and non-porous without glazing. Porcelain is fired between 1,260 and 1,400 degrees Celsius. It vitrifies completely, producing a white, translucent material that is the most refined and technically demanding ceramic body.
Glazes are glass-forming coatings applied to ceramic surfaces. A glaze is a mixture of silica (the glass former), fluxes (which lower the melting point), and stabilizers (which control the glaze's flow). When fired, the glaze melts into a thin glass layer that bonds to the clay surface. Glazes provide waterproofing, color, and surface texture. The chemistry of glazes is complex, involving variables of temperature, atmosphere (oxidation or reduction), and the interaction of metallic oxides that produce color. Iron oxide produces greens, blues, browns, and blacks depending on the firing atmosphere. Copper oxide produces reds in reduction and greens in oxidation. Cobalt oxide produces blue.
The earliest known ceramic objects are the Gravettian figurines from Dolni Vestonice in the Czech Republic, dating to approximately 28,000 BCE. The most famous, the Venus of Dolni Vestonice, is a small female figure fired in a simple kiln. These are not vessels but sculptural objects, suggesting that ceramics began as art rather than utility.
The first pottery vessels appeared during the Jomon period in Japan, around 14,000 BCE. Jomon pottery is among the oldest in the world, predating agricultural settlement. The Jomon people were hunter-gatherers who produced elaborately decorated vessels with impressed cord patterns (jomon means "cord-marked"). A 2025-2026 exhibition at the GRASSI Museum of Applied Arts in Leipzig, GEFASS / SKULPTUR 4, featured contemporary artist Ayaka Terajima's work drawing inspiration from Jomon ceramics, demonstrating the continuing relevance of this 14,000-year-old tradition.

In China, ceramics reached extraordinary technical sophistication during the Tang (618-907) and Song (960-1279) dynasties. Song dynasty Ru ware, Guan ware, and Ding ware are considered the pinnacle of Chinese ceramics, with subtle glazes and refined forms that have never been surpassed. The development of porcelain during the Tang dynasty, using kaolin clay fired at high temperatures, gave China a monopoly on porcelain production that lasted until the 18th century. The Jingdezhen kilns became the center of porcelain production, supplying the imperial court and exporting across the world.
In Korea, the Goryeo dynasty (918-1392) produced celadon ware with jade-green glazes that were prized in Chinese imperial courts. The Joseon dynasty (1392-1897) shifted to white porcelain, reflecting Confucian aesthetics of restraint and simplicity. The Gyeonggi Ceramics Biennale, held in Icheon, Gwangju, and Yeoju, continues this tradition. The 2026 edition, titled Earth Makes, runs from September 18 to November 1 and proposes a shift in how ceramics is understood, treating clay as an active collaborator rather than a passive material.

In the West, ancient Greek pottery (c. 1000-300 BCE) developed black-figure and red-figure techniques, where figures were painted in slip (liquid clay) that turned black during firing, against the red clay ground. Greek amphoras, kraters, and kylixes are among the most studied ceramic objects in art history. Roman ceramics spread standardized forms across Europe through industrial-scale production.
The Islamic world developed tin-glazed earthenware, which produced a white opaque surface suitable for painted decoration. This technique spread to Italy, where it became maiolica, to the Netherlands, where it became Delftware, and to France, where it became faience. The 16th-century Iznik pottery of Ottoman Turkey, with its red clay body and brilliant underglaze colors, is among the most accomplished ceramics of the period.
In the 20th century, the studio pottery movement rejected industrial production in favor of individual craft. Bernard Leach, who trained in Japan and established the Leach Pottery in St Ives, England, in 1920, bridged Eastern and Western ceramic traditions. Lucie Rie and Hans Coper, both working in London after fleeing Nazi Europe, brought modernist aesthetics to ceramics, producing vessels that were functional in origin but sculptural in effect. The GRASSI Museum exhibition noted above includes works by Rie and Coper as foundational examples of the studio ceramic movement.
Rie fled Vienna for London in 1938 and established a studio that produced some of the most influential ceramics of the 20th century. Her vessels are characterized by thin walls, precise forms, and innovative glazes. Rie's work bridges functional pottery and sculptural object, demonstrating that a vessel can be both useful and formally inventive. Her work is held at the Victoria and Albert Museum and the Sainsbury Centre for Visual Arts.
Voulkos broke ceramics out of the functional vessel tradition in the 1950s and 1960s. His large-scale stoneware sculptures, built from thrown and hand-built sections, slashed, punctured, and assembled, brought Abstract Expressionist energy to clay. Voulkos taught at the Otis Art Institute (now Otis College of Art and Design) and the University of California, Berkeley, where his influence shaped a generation of American ceramic artists.
Woodman combined ceramic vessels with painted decoration in works that referenced Etruscan, Greek, and Baroque ceramics while engaging with painting and sculpture. Her House of the South (1994-1995) is a room-sized ceramic installation held at the Stedelijk Museum. Woodman's work challenged the separation of ceramics from fine art by insisting on the vessel as a site for painting, sculpture, and architectural intervention.
Kuwata works in Shigaraki, one of Japan's historic ceramic centers, producing works that push traditional techniques to their limits. He uses stones that explode during firing, creating craters in the glaze, and applies gold and platinum to the damaged surfaces. Kuwata's work is included in the 2026 UCCA Clay exhibition Raw Modernism: Accolay Clay Today in Beijing, which juxtaposes historical Accolay workshop ceramics with contemporary practice. Read about the exhibition at UCCA.
Creten is regarded as a pioneer who secured ceramics a prominent place in contemporary fine art. His work moves between sensual, organic forms and conceptual critique. Creten is featured in the 2026 exhibition Clay Matters at Keteleer Gallery in Antwerp, which positions ceramics as "at once ancient and current, fragile and powerful, sensual and conceptual."

Ceramics has occupied an anomalous position in the art world for over a century. The medium is associated with functional objects, domestic labor, and craft traditions, which has led to its marginalization within institutions that prioritize painting and sculpture. The 2026 Keteleer Gallery exhibition text states: "Ceramics has long occupied a marginal position within the visual arts, often relegated to the realms of craft and applied art. Yet the medium possesses an age-old tradition of both functional and artistic significance. Over the past decades, artists have rediscovered and reinvented this material, allowing ceramics to emerge today as a fully-fledged and versatile medium within contemporary art."
This shift is visible in museum programming. The GRASSI Museum's GEFASS / SKULPTUR 4 exhibition (November 2025 to October 2026) explicitly explores the boundary between functional vessel and autonomous sculpture, asking: "Where does the vessel end, and where does sculpture begin?" The exhibition traces the evolution from post-war studio ceramics to contemporary practice, showing how ceramic artists have increasingly transcended utility. The RESPONS! Norwegian Ceramics 1975-2026 exhibition at the Center for Ceramic Art Ringebu documents 50 years of Norwegian ceramics, tracing the shift from functional production to autonomous artistic expression.

The Victoria and Albert Museum in London holds one of the world's largest ceramic collections, spanning ancient to contemporary. The Metropolitan Museum of Art has extensive Chinese, Korean, and Japanese ceramics. The Musee National de Ceramique in Sevres, France, focuses on European porcelain. The Gyeonggi Ceramics Biennale in South Korea runs from September 18 to November 1, 2026. The GRASSI Museum in Leipzig has GEFASS / SKULPTUR 4 on view through October 4, 2026.
If you want to understand ceramics, visit a pottery studio and watch someone throw a vessel on a wheel. The process takes minutes to observe but years to master, and seeing it done reveals why ceramics has captivated people for 28,000 years. The material is responsive, demanding, and transformative. It starts as mud and becomes stone. For more, read our entries on sculpture and clay, or explore our guide to ceramics and pottery.
