Copper and Iron Are Treasures Too: The Tibet Series
ཨོ་ཌི་བི་ཤ་ནས་ཐོན་པའི་ལྕགས་ནག་གིས་ཤ་རུས་ཡོངས་སུ་གཅོད་པར་ནུས། བརྡབ་པ་ཐེངས་གཅིག་གིས་གླང་ཆེན་གྱི་གཟུགས་ཕྱེད་ཀར་གཏུབ་ཐུབ། དེ་ནི་གསེར་དང་རིན་ཆེན་དང་གཞི་རིན་འདྲ་བའི་ནོར་བུ་ཞིག་ཡིན་པར་མི་ཚང་མས་ཁས་ལེན།
རྒྱ་ནག་གི་ལྕགས་བཟང་ནི་རྣོ་ཞིང་བརྟན་པོ་ཡིན་ལ། ལྕགས་ངན་གྱིས་ངར་ཤུགས་མེད་ཀྱང་བཟོ་རིགས་སྣ་ཚོགས་བཟོ་ཐུབ། བོད་ཀྱི་ལྕགས་དཀར་ནི་ཞོ་ཞིང་བླུགས་པར་འཚམ་པོ་ཡོད། ཁམས་ཀོང་གི་ལྕགས་ནི་ངར་ཤུགས་ལྡན་པས་སོ་ནམ་ལག་ཆ་རུ་བཀོལ་ཆོག
The superior iron originating from Odvisha has the power to cut through bone and flesh as easily as one chops down a tree. A single blow is capable of slicing an elephant's body in half. It is widely acknowledged that this treasure carries a value equal to that of gold.
Kham and Kongpo iron is sharp and most suitable for farming tools; Tibetan iron, white and soft, is ideal for making bowls; inferior iron is blunt yet apt for crafting implements; and Han iron is sharp while being both hard and supple. — From *A Concise Guide to Analyzing Precious Substances* （རིན་པོ་ཆེ་བརྟག་ཐབས་མདོར་བསྡུས་གསལ་བ་） By Longdol Lama Ngawang Lozang ( ཀློང་རྡོལ་བླ་མ་ ; 1719-1794). Note: "Odvisha" refers to present-day Odisha in South Asia, which ancient Buddhist texts call Kalinga (ཀ་ལིང་ཀ་); this area engaged in considerable metal trade with Tibet.
Among the natural copper varieties are iron-bearing, gold-bearing, and various iron ores. When struck, iron-bearing copper yields a rough sound and is referred to as "male copper." Gold-bearing copper, in contrast, gives off a bright, ringing note and is known as "female copper." ལི་དཀར་ལི་སེར་ལི་དམར་དང། ལི་ཁྲ་ལི་སྨུག་རོལ་མོ་བཅོས། སྐད་སྙན་བྱུང་ན་བཟང་བ་ཡིན། སྐད་མེད་མདོག་ནག་བལ་པོ་དང། ཁམས་བོད་ལི་བརྫུས་སྣ་ཚོགས་འབྱུང། （…..） མོ་རག་རྡོ་རག་སེར་ཞིང་གྱོང་མཉེན་ལེགས། ཕོ་རག་རག་སྐྱ་བཅོས་པའི་རག་ཡིན་ངན། པད་སྡོང་དངུལ་འདྲ་ངན་པ་འཁར་བ་འདྲ། ལྗོན་དམར་ཟངས་འདྲ་སྡོང་དཀར་ལྕགས་དཀར་འདྲ། **Three Types of Bell-Metal: White, Yellow, and Red** Instruments fashioned from variegated and purple bell-metal are excellent—those with clear, pleasing tones rank highest, whereas ones with muted, dark sounds are deemed lesser.
In Nepal, Tibet, and Kham, forgeries are widespread. Two types of brass are distinguished: "female brass-ore," which is yellow and varies in hardness, and "male brass," which is pale and produces lesser-quality goods. It is likened to silver lotus stems—nearly as good as bell-metal—and to copper-red trees that appear whitish like tin. This comes from *A Concise Guide to Analyzing Precious Substances* (རིན་པོ་ཆེ་བརྟག་ཐབས་མདོར་བསྡུས་གསལ་བ་) by Longdol Lama Ngawang Lozang (ཀློང་རྡོལ་བླ་མ་; 1719-1794). *Note: "Nepal, Tibet, and Kham" denotes Nepalese regions, Central Tibet, and the eastern Kham area.
A Bronze Casket and Iron Nails: The Sovereign's Remains Cast into the River. The king-father's remains were thrown into the river after being placed in a copper coffin and nailed shut with iron. A treacherous minister then took the throne, and the prince went into exile, beginning a thirteen-year saga of revenge. Ultimately, the prince reclaimed his rightful throne with help from a loyal advisor, and the people used copper and iron to punish the conspirators. "Stems and sacred trees" are classical metaphors, where "stem" refers to white lotus stalks.*
Historical Tibetan sources record Rulakye (རུ་ལས་སྐྱེས་) and his son Lhabu Gokar (ལྷ་བུ་མགོ་དཀར་) as exemplary ministers of the empire. Under their stewardship, Tibet's agriculture and metallurgy thrived. A narrative handed down from the era of the Tibetan empire assigns deep symbolic weight to "copper and iron"—metals that stood witness to the dynasty's most trying period. The prince who regained the throne was Pude Gungyal (སྤུ་དེ་གུང་རྒྱལ་ / པུ་དེ་གུང་རྒྱལ་), Tibet's ninth emperor, and his shrewd counselor was none other than Rulakye.
Archaeological evidence from recent decades indicates that Tibetan civilization had already entered the Bronze Age at least 4,000 years ago. For that reason, this period cannot be described as the origin of metallurgy in Tibet. The earth yielded eight essential metals: gold, silver, red copper, tin, iron, brass, bronze, and lead. Gold, silver, copper, iron, and tin—or, according to some texts, gold, silver, iron, red copper, and bronze—were equally available to rulers, ministers, and common people.
South Asian legends claiming that copper derived from a "red tree" (ལྗོན་དམར་) endured for a long time in Tibet. The earliest copper employed was red copper, its dark hue likened to a "barbarian's face" (ཀླ་ཀློ་ཁ་). Hardened iron served as the material for weapons (མཚོན་ཆ་བྱེད་པ་). During the era of Pude Gungyal, the Iron Age likely reached its twilight. Evidence points to extensive metallurgical exchanges—particularly involving copper and iron—between Tibet and East, South, and North Asia.
In classical times, brass and bronze—both copper alloys—drew considerable scholarly debate. While brass (ར་གན་ / རག་) with its golden hue served as the standard for sacred images, bronze was likened to a lotus and given the title 'stainless material' (དྲི་མེད་རྫས་). The Tibetan tradition, though the matter is debated, discerned two kinds of bronze: high-tin bronze (ལི་, or 'bell-metal'), deemed superior, and ordinary bronze (འཁར་བ་), which possessed its own distinction.
In contemporary academic discourse, multiple mutually supplemental theories address Thokcha (གནམ་ལྕགས་). Still, current literature indicates that the history of excavating Tibetan copper/iron ores, the development of copper/iron craftsmanship, and related mineralogical investigations all demand further in-depth collation and refinement. Meanwhile, modern archaeology and ore research have undeniably contributed a range of novel viewpoints.
Several ongoing lines of inquiry continue to enhance our comprehension of metallurgical systems in Tibet (especially gold, silver, copper, and iron). These include Western Tibet's central significance in proto-historical metallurgy, the link between copper/iron technologies and early sociopolitical power structures, and fresh interpretations of conventional terminology.
In indigenous beliefs, metal artifacts were thought to possess an intrinsic vitality and functioned as ritual intermediaries. Some craft treatises metaphorically link copper to yin and iron to yang—with gold left out—thereby implying a social symbolism. Tibetan descriptions, meanwhile, tend to set apart copper/alloy-cast ritual objects and iron-forged weapons, although this distinction is not absolute.
In central Tibet, a traditional division existed: gold, silver, and copper smiths were termed "white artisans" (དཀར་བཟོ་), while ironworkers were labeled "black artisans" (ནག་བཟོ་), a category marked by stigma and later tied to "ritual impurity" stemming from bloodshed involved in weapon production. During the imperial era, however, the social standing of artisans rose due to growing military needs and the subsequent stylization of Buddhist iconography; historical sources even reveal that the clan of minister Gar Tongtsen were blacksmiths.
Even though metalworkers, especially blacksmiths, continued to endure social marginalization, they stayed essential craftsmen during the Ganden Phodrang period, which saw the formation of formal guilds with written regulations. These artisans produced both sacred implements and everyday utilitarian objects.
Translated from SuolangWangqing's blog, this article examines Tibet's "blacksmith stigma" as a localized normative system. Pema Lingpa (པདྨ་གླིང་པ་; 1450-1521) learned blacksmithing from an early age and created sacred copper and iron objects. The mahasiddha Thangtong Gyalpo (ཐང་སྟོང་རྒྱལ་པོ་; 1385-1509), depicted at lower right, began as a blacksmith himself and directed the construction of numerous iron bridges throughout the Himalayan region. Such discrimination was rarely exhibited in Buddhist systems or South Asian societies.
