What is the color terracotta?

Terracotta is a unique earthy red-orange color that has been used in art and architecture for centuries. The name “terracotta” comes from the Italian word for “baked earth”, referring to the process of firing clay to produce the distinctive hue. Terracotta clay is rich in iron oxide, which gives it its warm reddish tones when fired at high temperatures. As both a beautiful color and versatile building material, terracotta has an illustrious history spanning cultures and millennia.

What is Terracotta?

Terracotta is a type of earthenware clay that is fired at high temperatures until it becomes hard and durable. It’s composed of a variety of natural clays and minerals that create its distinctive color and texture. True terracotta begins as a type of clay called terracotta clay, which contains higher amounts of iron oxide than other clays. When terracotta clay is fired at very high temperatures – generally between 1500-2200°F – the iron oxide undergoes a chemical reaction and causes it to flux, resulting in the warm reddish-orange coloration.

While the raw terracotta clay starts out grayish or yellowish in tone, the high firing temperature transforms it into the familiar earthy, rusty red-orange color. The longer it’s fired and the higher the heat, the more intense and even the final terracotta color will be. While the iron content determines the hue, substances like manganese can modify the color towards warmer brownish tones. Once fired, true terracotta maintains its hardy, porous nature and rich color.

History and Origins

The use of terracotta as a building material and decorative element is incredibly ancient. Early civilizations quickly realized that naturally occurring terracotta clay could be molded when wet, baked into useful vessels or tiles, and used in architectural construction. Fired terracotta also withstands weathering and lasts centuries, as many ancient structures and artifacts still stand today.

Prehistory and Antiquity

The first uses of fired terracotta date back over 30,000 years to prehistoric China and the Eurasian Steppe. Neolithic cultures crafted simple pots and religious figures in basic fired clay. By 3000 BCE, Bronze Age cultures like the Indus Valley and Mesopotamian civilizations were creating sophisticated terracotta works, using advanced kilns to produce intricate sculptures, pipes, bricks, and decorations.

Ancient Mediterranean cultures continued to develop terracotta craftsmanship and construction techniques. Minoans and Mycenaeans produced terracotta jars, figurines, pipes, and decorations in Crete and mainland Greece during the 2nd millennium BCE. Ancient Greek potters perfected the famous, distinctive Greek red-figure and black-figure pottery between 600-300 BCE.

Ancient Roman potters developed thin-walled terracotta vessels and amphorae for transporting goods across the Empire. Romans also pioneered more advanced firing techniques, allowing them to create large-scale terracotta bricks and tiles for architectural uses.


In Asia, Chinese potters had begun developing porcelain ceramics during the Shang Dynasty (1600-1046 BCE), abandoning terracotta as finer wares emerged. However, Chinese brick and tile-making refined firing methods to acheive diverse colors and finishes. Complex polychrome decorations in terracotta, called doucai, developed during the Tang Dynasty (618-907 CE).

In Japan’s Kofun period (300-700 CE), fired terracotta was used to make haniwa funerary figures placed around burial mounds. During the Nara period (710-794 CE), craftsmen used terracotta to create elaborate roof decorations, tiles, and ornaments for Buddhist temples.

Indian craftsmen similarly created terracotta temple decorations. The advanced firing techniques of India’s Mauryan Empire (322-187 BCE) allowed artisans to develop the refined rouletting and slipping techniques seen on terracotta Stupas at sites like Sanchi.

Islamic World

From the 8th century CE, Islamic artistic traditions enthusiastically embraced terracotta. Brightly colored terracotta became a signature decorative element, covering mosques and madrasas across the Islamic world in ornate patterns and calligraphic script. Persian artisans excelled in complex mosaic tilework, while Ottoman Turks developed cuerda seca tiling using terracotta outlined with black to create intricate floral motifs.

Medieval Europe

While ancient Romans had brought terracotta craftsmanship to Europe, fewer large-scale works survived the collapse of the Empire. However, around the 12-13th centuries, terracotta sculpture and decorative work reemerged across Christian Europe. Italian artisans led the way creating elaborately painted terracotta reliefs and freestanding sculptures. Terracotta plaque reliefs covered exteriors of churches and civic buildings. Spain and Germany also produced impressive terracotta altarpieces and devotional works. Gothic architects developed more durable terracotta facade decorations. Across Europe, terracotta replaced stone around fireplaces and heating vents as a fireproof material.

Renaissance and Baroque

During the European Renaissance, terracotta sculpture reached new heights through the works of acclaimed masters like Donatello and Andrea della Robbia. Their realistic, emotionally expressive fired clay sculptures influenced generations. Della Robbia also developed an innovative glazing technique to create his signature colorful tin-glazed terracotta works.

Baroque-era artists also mastered realism in terracotta. Bernini’s intimate religious terracotta sculptures expressed piety through their dignified but approachable materia. Elaborate terracotta friezes and reliefs adorned palaces and churches with movement and drama. Dutch Golden Age still life painters accurately captured the earthy texture of terracotta in their compositions.

Types and Styles

Within the broad category of fired terracotta, there are a few recognized types that vary based on composition, construction method, and firing technique:


The most common variety, earthenware encompasses most simple, low-fired terracotta objects. Earthenware can be unglazed or covered with glazes and paints to add colors and finishes. The clay body tends to be porous and opaque. Firing temperates are usually below 2200°F. Some ancient Greek pottery and Roman amphorae were simple earthenware.


Denser and less porous than earthenware due to higher mineral content, stoneware is fired at 2200-2400°F. The clay body vitrifies and becomes watertight, making stoneware suitable for vessels and outdoor uses. Chinese Ding ware porcelain developed from stoneware techniques. Imperfect vitrification can leave attractive spotting called té mouche.

Terracotta Tiles

One of the most common architectural uses, terracotta tiles have been created for millennia across the world. Tiles can be glazed or unglazed and shaped by press-molding or extrusion. Ornate relief tiles decorated buildings from Ancient Persia to Gothic cathedrals. Durable terracotta roof tiles were a practical Roman invention that became ubiquitous in Europe and Asia.

Terra Sigillata Ware

A refined Roman tableware inspired by earlier Greek pottery. Its smooth, shiny red surface was achieved by burnishing and polishing slip (liquid clay). Often decorated with barbotine (relief) motifs or sigillata (stamped) designs.

Medieval Terracotta

During Europe’s medieval era, artisans created religious sculpture and decorations in terracotta. Figures and narrative reliefs covered churches and cathedrals, particularly in Italy. Developers favored bright polychrome finishes and gilding. Trecento works featured greater realism and emotion.

Della Robbia Terracotta

Developed by Renaissance sculptor Andrea della Robbia and his family in Florence. Characterized by idealized blue and white tin-glazed reliefs in high-relief. Subjects were typically religious, classical, or allegorical.

Characteristics and Properties

Terracotta possesses many inherent qualities that have made it a popular medium and building material since ancient times:

Earthy Natural Appearance

The warm, earthy colors and texture give terracotta a distinctive rustic, organic appearance. The matte surface and variegated shades evoke raw natural clay. Glazes can enhance color while retaining some natural imperfections. The terracotta hue is welcoming and familiar.


In its pre-fired wet form, terracotta clay is very malleable and responsive to shaping and carving techniques, allowing artisans great flexibility and control. Refinement can be easily carved out after drying or firing. The smoothness or coarseness of raw clay determines surface texture.


When properly fired, terracotta becomes very hard and durable while retaining some natural porosity. Its density and low permeability allow architectural works like bricks, flooring, and decorations to withstand weathering and last decades or centuries with minimal deterioration. Well-preserved artifacts prove its longevity.

Fire Resistance

Already fired once, terracotta resists fire very well compared to other building materials. This made it ideal around heating systems in homes and industries. Terracotta walls, tiles, and decorations survive kiln accidents and building fires when other materials burn or melt away.


Fired terracotta is much lighter than materials like stone or concrete, despite its durability. This made transporting and working with terracotta feasible for many ancient cultures without advanced technology. It reduced construction weight for floors, walls, and ceilings compared to heavier alternatives.


Beyond sculpture and pottery, terracotta could be shaped into an incredible range of architectural elements, vessels, tools, household objects, decorations, and reliefs. Combined with a variety of surface treatments like glazes and slips, its creative applications were virtually endless. The same material could fulfill functional and aesthetic roles.


Accessible terracotta clay resources allowed most ancient societies to utilize this versatile material, regardless of wealth and status. Firing methods could be simple or sophisticated. Decorative options like paints and glazes allowed personalized embellishment at any budget. Terracotta was a democratic medium.

Uses and Applications

Thanks to its many favorable properties, terracotta has served a vast array of cultural, architectural, and decorative uses across different civilizations and eras:


As an accessible modeling material, terracotta has been used for sculptural arts since antiquity. From small Greek Tanagra figurines to towering Renaissance statues, terracotta granted sculptors flexibility in surface textures, poses, and sizes. It captured subtle details and emotions more affordably than stone.

Pottery and Vessels

The most ubiquitous and practical terracotta artifacts have always been vessels of all types and sizes, from cups to urns to grain storage. Terracotta amphorae transported goods across ancient Greece and Rome. Decorated vases were treasured for their beauty while also holding contents.

Tiles and Flooring

Impervious to heat and moisture, terracotta tiles have covered floors for centuries worldwide. Tiles extended from Turkey to the Netherlands to Mexico. Durable terracotta protected mudbrick ziggurats in Ancient Mesopotamia and insulated Roman hypocaust systems.

Decorative Reliefs

From ancient cultures to Baroque Europe, one of terracotta’s most prized decorative elements has been relief panels. Terracotta accepted precise sculpting and held fine details. Reliefs adorned temples, homes, palaces, civic buildings, and churches for ornament and storytelling.

Bricks and Construction

Used structurally since ancient Mesopotamia, terracotta bricks endure for millennia. Roman innovations led to widespread architectural brick use in Europe and Asia. Lighter than stone, terracotta reduced building weight while amplifying beauty through brick patterning.


Following the Roman discovery that curved tiles could efficiently waterproof roofs, terracotta roofing spread from Asia to Europe. Durable, fireproof terracotta roof tiles outlasted thatch and shingles across climates. Decorative elements turned roofs into architectural displays.

Plumbing and Piping

Impervious to liquids and gases, high-fired stoneware and porcelain allowed sophisticated terracotta plumbing systems to emerge in Asia, North Africa, and Europe before modern pipes. Terracotta pipes supplied water and removed waste on a grand scale.

Chimneys and Fireplaces

As a fireproof material effective at dissipating heat, terracotta lined fireplaces and chimneys from medieval Europe onward. Kiln technology refinements led to efficient flue systems and dazzling decorative mantelpieces that spread from noble halls to modest homes.


Beyond sculpture and vessels, terracotta furnishings added color and whimsy to interiors when painted and glazed. Ornamented floor vases, busts, plaques, figurines, and flowerpots enlivened elite Western homes. Terracotta garden seating welcomed nature indoors.

Artistic Medium

Terracotta’s smooth surface provided the ideal painter’s ground for frescoes, circus, and tile murals across the Eastern and Western worlds. While vulnerable to environmental damage, examples like the Terracotta Army in China give a glimpse of vibrant original polychrome artworks.

Geographic Origins and Locations

Abundant terracotta clay deposits allowed nearly all ancient civilizations access to this versatile medium. While used globally today, some locations became renowned for their terracotta heritage and innovations.


Some of the world’s first and finest terracotta artworks came from China where porcelain was also invented. Chinese pottery influenced Japan and Korea. Chinese brickmaking allowed large pagodas. The Terracotta Army still inspires awe.


The cradle of civilization in ancient Iraq and Syria contains some of the world’s oldest terracotta artifacts. Sumerians, Assyrians, and Babylonians used terracotta for sculpture, bricks, ceramics, and tiles for their ziggurats and palaces.

Ancient Greece

Greek artisans perfected the formula for strong, thin-walled pottery, allowing delicate red and black-figure decoration on terracotta vases. Terracotta figurines were common. Elaborate antefixes crowned temples.

Ancient Rome

Expanding on Greek and Etruscan work, Romans engineered terracotta for monumental architecture. Roman bricks, tiles, statuary, and pottery spread across their Empire. Italy is still known for terracotta.


Indian terracotta spanned functional pottery to ornate architectural reliefs covering stupas and temples. Advanced firing techniques allowed especially refined wares. Terracotta figurative sculpture also flourished.

Persia and Turkey

Highly skilled Persian and Ottoman artisans produced some of the world’s most complex, colorful terracotta mosaic tiles and cuerda seca decorative work from the 10th-17th centuries across mosques and palaces.

Medieval Europe

After centuries of decline in Europe, terracotta enjoyed a revival across France, Germany, Spain, and especially Italy where sculptors like Donatello created naturalistic works. Polychrome terracotta altarpieces and reliefs dominated.

Central America

Pre-Columbian American cultures like the Olmecs, Aztecs, and Mayans produced terracotta utilitarian and ceremonial works including piggy banks, flutes, figures, shrines, and burial goods.
