Understanding Why Sancai Glazed Pottery Dominates Tang Dynasty Tombs

Archaeological records present a clear pattern: a vast majority of surviving sancai glazed pottery comes from the tombs of the Tang Dynasty elite. This strong association often leads to the assumption that these vibrant, three-colored ceramics were made exclusively for the afterlife. But is that the complete story? The answer lies in understanding the unique cultural practices, social status, and symbolic meaning embedded in these remarkable objects.

The prevalence of sancai wares in burial contexts is not an accident. It is a direct reflection of the beliefs and social hierarchies of the Tang Dynasty (618–907 AD), a period of unprecedented wealth, cosmopolitanism, and artistic expression in Chinese history. These objects were not merely decorations; they were essential equipment for the journey into the next world.

The Role of ‘Mingqi’ in Tang Funerary Culture

To grasp why sancai glazed ceramics filled the tombs of the wealthy, one must first understand the concept of mingqi (冥器), or “spirit goods.” These are objects created specifically for burial to serve and accompany the deceased in the afterlife. The practice was rooted in a belief that the afterlife mirrored earthly life, requiring servants, soldiers, entertainers, animals, and provisions.

In earlier dynasties, this belief led to the horrific practice of live human and animal sacrifice. Over time, these real-life sacrifices were replaced by replicas made from wood, bronze, and eventually, mass-produced ceramics. During the Tang Dynasty, this practice reached its artistic and industrial zenith with the development of sancai-glazed earthenware.

The production of mingqi was a major industry, regulated by the state. Sumptuary laws even dictated the number and size of burial figures an individual was permitted based on their social rank. A high-ranking general might be buried with an army of ceramic soldiers, while a minor official would have a much smaller retinue. Sancai wares, with their brilliant colors and impressive forms, were a clear and powerful display of the deceased’s status and wealth, intended to ensure their comfort and high station in the world to come.

Common Forms of Sancai ‘Mingqi’

• Guardian Figures: Fierce mythological beings and heavily armed officials (Lokapala) were placed at the tomb’s entrance to ward off evil spirits.
• Horses and Camels: These were potent symbols of power and wealth. Ferghana horses represented military might and aristocratic prestige, while Bactrian camels symbolized the immense riches flowing from trade along the Silk Road.
• Human Figures: A wide array of figures represented the deceased’s household, including court ladies, musicians, servants, and foreign merchants, all meant to continue their service in the afterlife.
• Architectural Models: Miniature replicas of houses, granaries, and even toilets were included to provide the deceased with familiar comforts.

Burial Wares vs. Domestic Use: An Archaeological Perspective

While the overwhelming evidence points to a funerary purpose, were sancai glazed wares ever used by the living? The archaeological record provides a nuanced answer. By comparing the types of objects found and their locations, we can clearly distinguish between items made for burial and those intended for daily life or trade.

The key distinction is between purpose-built symbolic items (mingqi) and functional vessels. While both might use sancai glazing, their forms, find spots, and prevalence tell different stories.

This evidence shows that while a small number of sancai glazed vessels were produced for use, the vast majority of production was dedicated to the funerary industry. The vibrant, somewhat fragile, and potentially toxic nature of the lead-silicate glaze made it perfect for the symbolic, one-time use of a tomb but less practical for everyday kitchenware.

Production Technique and Its Symbolic Implications

The term sancai (三彩) translates to “three colors,” but the palette could include more. The most common colors were amber/brown (from iron oxide), green (from copper oxide), and a creamy off-white or yellowish straw color (the natural color of the slip). Cobalt was sometimes used to produce a brilliant blue, a highly prized and expensive color.

The process involved a low-fired earthenware body, typically a white or buff-colored clay, which was first fired to a biscuit state. A thin layer of white slip was often applied. Then, the lead-fluxed glazes were applied by splashing, dripping, or painting them onto the object. During a second firing at a relatively low temperature, the glazes would run and fuse, creating the fluid, vibrant, and sometimes unpredictable patterns that define the style. This “running” quality was embraced as part of its aesthetic appeal.

This production method had several implications:

• Efficiency: The process allowed for relatively rapid and large-scale production, necessary to meet the high demand for tomb furnishings.
• Aesthetic: The bright, jewel-like colors stood in stark contrast to the more somber, monochrome high-fired wares of the time, making them visually spectacular for their intended symbolic purpose.
• Imperfection: The low firing temperature meant the ceramic body remained porous and fragile, making it unsuitable for durable, long-term use as a water or food vessel.

Checklist for Assessing Sancai-Style Ceramics

For collectors, researchers, and importers, understanding the context of sancai production is crucial for evaluation. Distinguishing authentic period pieces from later reproductions requires careful examination. While professional authentication is always recommended for high-value items, this checklist provides a starting point for initial assessment.

Buyer’s Decision Checklist:

1. Evaluate the Form and Function: Does the object’s shape align with known Tang Dynasty mingqi (e.g., a horse, a guardian) or the rarer utilitarian forms (e.g., a tripod dish)? Reproductions often mix forms or have anachronistic details.
2. Analyze the Glaze Characteristics: Authentic sancai glazed surfaces often exhibit fine crazing (a network of tiny cracks in the glaze) and some iridescence or degradation from centuries of burial. The colors should have a soft, deep brilliance, and the “running” of the glazes should look natural, not overly controlled.
3. Inspect the Unglazed Body: Examine the base or any unglazed areas. The underlying earthenware should be relatively light, porous, and buff or pinkish in color. The base of a tomb figure is often unfinished and may show traces of the original soil.
4. Look for Signs of Age and Burial: Authentic tomb pottery often has small amounts of soil encrustation or mineral deposits (calcification) in crevices that are difficult to fake convincingly. These should be examined carefully, as they can also be artificially applied.
5. Scrutinize the Craftsmanship: While made in large numbers, Tang sancai figures possess a vitality and expressiveness that is hard to replicate. Modern copies can feel stiff, lifeless, or overly perfect.
6. Request Provenance and Testing: Ask for the object’s history of ownership (provenance). For significant acquisitions, a thermoluminescence (TL) test report provides scientific confirmation of the last firing date, offering strong evidence of authenticity.

In summary, sancai glazed wares were predominantly a funerary art form, a spectacular and status-affirming product of Tang Dynasty beliefs about the afterlife. Their discovery within tombs is the primary reason we have such a rich and detailed understanding of them today. While some pieces were used by the living, their story is overwhelmingly tied to the silent, subterranean world they were made to inhabit.
