[Culture & Heritage] The Making of Korea's Red Burnished Pottery: Pigment...

When discussing Bronze Age pottery on the Korean Peninsula, the most representative artifacts are generally plain coarse pottery vessels known as “Mumun pottery.” The Bronze Age on the peninsula began around the 15th century BCE. Although the period is named after the appearance of bronze, pottery remains the most widely discovered material in archaeological sites.

In a broad sense, Mumun pottery refers to Bronze Age pottery overall. In a narrower definition, it describes reddish-brown or yellowish-brown vessels made from unrefined clay, roughly finished, and fired at temperatures below 800 degrees Celsius. The name itself refers to the absence of decorative patterns. However, Bronze Age archaeological sites also reveal pottery decorated with patterns and colored surfaces.

Representative examples include red burnished pottery and black-pattern pottery. Neolithic pottery was often decorated by attaching clay strips or carving and pressing designs with tools. Bronze Age colored pottery instead created surface effects through pigments and firing techniques.

Red burnished pottery was made using refined clay coated with red pigment and polished to create a glossy surface. Black-pattern pottery achieved dark patterns by covering certain areas with clay or other materials before firing. The defining features of red burnished pottery are its red coloration and “maryeon” (磨硏), a polishing process used to smooth and shine the surface.

Neither red pigment application nor polishing techniques first appeared during the Bronze Age. Rare examples of red-painted pottery and smoothed surfaces are already found in the Neolithic period.

The key difference lies in the treatment of gloss. Many Neolithic examples were simply coated in red pigment, while Bronze Age red burnished pottery was polished after coloring to create shine. For this reason, Neolithic red pottery is sometimes separately referred to as “red-painted pottery.”

The production process was relatively complex. Fine clay was rolled into strips and stacked to shape the vessel. The surface was then refined by hand or with tools before red pigment was applied. Once partially dried, the surface was polished so the pigment adhered properly and developed gloss. After drying, the vessel was fired.

Recent scientific analysis suggests that the red pigment may have been created using “seokganju” (石間朱), a reddish soil rich in iron oxide. Researchers also identified components associated with lacquer coating on analyzed pottery samples. Conservation scientists have proposed that lacquer may have been used to help pigments adhere more firmly to the surface. The interpretation suggests that prehistoric pottery production combined color technology, adhesion techniques, and polishing methods together.

The forms of red burnished pottery were not entirely separate from other Mumun pottery traditions. They broadly shared common Bronze Age vessel types, though preferred forms varied by period.

Bronze Age pottery is generally divided into jars, bowls, and pedestal vessels. Jars are classified according to neck length, while bowls widen toward the rim and may be either deep or shallow. Pedestal pottery includes vessels with attached stands, such as pedestal jars and pedestal bowls. Deep, neckless vessels with inward-curving rims are sometimes categorized as “ong” storage jars, while shallow wide-rim bowls are referred to as “wan.”

Early Bronze Age red burnished pottery frequently appeared in pedestal vessel and jar forms. This differs from the broader Mumun pottery pattern, where bowls and jars dominate. During the spread of Songguk-ri culture, pedestal vessels largely disappeared. Instead, flask-shaped jars, small storage jars, and bowls became common forms of red burnished pottery.

Compared to ordinary Mumun pottery, red burnished pottery appears in much smaller quantities. Its production also required significantly more labor, including selecting refined clay, applying red pigment, polishing surfaces, drying, and firing.

Excavations reveal that red burnished pottery is found more frequently in tombs than in residential sites. Researchers therefore argue that these vessels were likely more than simple burial objects. Because the vessels retained functional forms, they may have contained materials placed inside tombs. Some scholars also suggest that the polishing process created denser surfaces with stronger water resistance than ordinary Mumun pottery, raising the possibility that liquids were stored inside.

The color red carried strong symbolic meaning in burial rituals. Associated with blood, it may have represented vitality, rebirth, or protection against harmful forces. In some cases, lumps of red pigment themselves have been discovered inside tombs. At the Janghang site on Gadeokdo Island from the Neolithic period, red pigment was found beside the left arm of Burial No. 35 and beside the arm of Burial No. 41, believed to belong to a child around four years old.

As agriculture developed and communities formed during the Bronze Age, ritual activities also expanded. Red burnished pottery has been discovered not only in tombs but also in house sites, around large building posts, near rice paddies and fields, inside ditches, and within pits. Unlike tomb examples, discoveries from living spaces are often fragmented.

These broken fragments may simply reflect use in daily life, but some researchers interpret them as intentionally broken during ritual practices. The pottery may have been connected to ceremonies seeking village stability, agricultural abundance, or communal order.
