Barro Negro: Beautiful Black Oaxaca Pottery

Pottery is an ancient art found in almost every corner of the world. Yet, no two cultures’ traditions are identical. In its variation and beauty, traditional pottery arts are still compelling to modern travelers.

Part of it is the art’s romance. Sculptor Erin Hicks once described clay pottery by saying, “There are no happier people on this planet than those who decide that they want something, define what they want, get ahold of that feeling even before its manifestation, and then joyously watch. Watch as, piece by piece, it begins to unfold. That’s the feeling of your hands in the clay.”

That sense resonates as people connect with the contemporary clay arts and ancient pottery traditions. In Oaxaca, Mexico, one such tradition is barro negro. Discover what makes this traditional black pottery form unique, and learn how potters today are preserving this ancient Mexican ceramic art.

What Is Barro Negro?

“Barro negro” means “black clay.” Barro negro pottery is a unique style of clay pottery and sculpture with roots in the ancient cultures of Oaxaca, Mexico. Certain regions of Oaxaca, including San Bartolo Coyotepec, have naturally black clay in the soil. This clay is traditionally used to create a unique form of useful sculptural art that doesn’t require pottery wheels to make.

In addition to naturally black clay, certain barro negro sculptures are further blackened by artful processes. For instance, lama Oaxaca black pottery uses mud clay mixed with crushed ore.

Stylistically, barro negro sculptures incorporate coiling and loop techniques, engraving, and burnished elements, integrating designs directly into the sculpture itself rather than embellishing its surface. Often, black pottery uses visual motifs and mythology from ancient Oaxacan cultures, including Zapotec and Olmec culture.

Originating The Art of Black Clay Oaxaca Pottery

The unique art of barro negro pottery, or black clay pottery, dates back to the ancient Zapotec culture and nearby civilizations in and around Monte Alban, Oaxaca likely as early as 500 B.C. Ancient pieces were crafted from naturally black clay in the region—particularly in San Bartolo Coyotepec.

Over the centuries, techniques were improved and honed to cultivate a unique, traditional cultural style. By the 20th century, the Oaxaca barro negro style was iconic: wholly unlike pottery anywhere else.

Black Pottery Technique Cultivated In San Bartolo Coyotepec

The clay naturally found in the earth of San Bartolo Coyotepec in Oaxaca is unique. It’s black in color, due to the clay’s high iron content. When fired in a low-oxygen kiln, the pieces cast in the iron-rich clay turn deep black and develop a matte metal surface.

The iron-rich clay is a natural resource protected and cultivated by the artists of San Bartolo Coyotepec. Over the centuries, artisans perfected the technique of highly controlled, low-oxygen kiln firing. Low-oxygen kiln development was a well-kept secret, and key steps in the process of creating deep black pottery remained a mystery to outsiders for generations.

The Barro Negro Process: How Is Oaxacan Pottery Made?

Today, more of those secrets are out in the open.

In Oaxaca, the process of making black pottery today is very similar to the process artists used 2,500 years ago—with a few improvements.

In both ancient and modern Oaxaca, black clay is mined from deposits in San Bartolo Coyotepec. It’s then prepared by hand to make it more plastic and pliable. Preparation can involve further blackening the clay, though not in every case. Then, the pliable clay is sculpted in layers, without the use of a potter’s wheel. After pieces are sculpted, they’re sun-dried to reduce internal moisture before being forged in a kiln.

Over the course of centuries, Oaxacan potters innovated to improve the process. Sculptural methods introduced over time include charring sculptures while firing them in kilns of thick, black woodsmoke, and using coil layers to visually emulate the appearance of “weaving” in certain basket-like pieces.

In the 1950s, the artist Doña Rosa Real developed a way to burnish the clay before firing. Right as a piece was almost completely dry, Real would polish the surface with quartz. After firing, quartz-polished pieces had a shiny, metallic black finish rather than a muted, matte surface. This finish was incredibly popular, and it’s now the most iconic Oaxacan pottery style.
