tutenag

Tutenag is a zinc-based alloy of zinc, copper, and nickel that craftsmen in Yunnan and Guangdong provinces had produced for centuries before European traders encountered it. The alloy resists tarnishing and carries a silver-white surface that made it attractive for candlesticks, tea caddies, and furniture mounts. East India Company records from the late seventeenth century contain some of the earliest European references to the material.

The English word arrived through Dutch toetenag or Portuguese tutênaga, both borrowed from a Hindi or Persian source. The Persian compound tūtiyā-nāg points to tūtiyā, the Arabic-Persian word for zinc oxide or zinc vitriol, itself possibly from Sanskrit. The second element, nāg, is disputed: it may denote a base-metal category, a geographic qualifier, or a grade designation used in the South Asian trade.

In the eighteenth century, tutenag was frequently confused with paktong (白銅, baitong, white copper), a related Chinese alloy with higher copper content and a slightly warmer tone. English and Dutch importers used the two names interchangeably for decades, and systematic chemical analysis only separated them clearly in the 1780s. European metallurgists examining East India Company samples eventually demonstrated that paktong and tutenag differed in composition, though both belonged to the broader family of zinc-based white alloys.

By the early nineteenth century, European manufacturers had learned to produce similar alloys domestically. German silver and nickel silver, developed in the 1820s in Germany and Britain, offered industrial-scale production at lower cost than the imported material. Tutenag faded from commercial language within a generation, surviving mainly in historical inventories, East India Company ledgers, and museum catalogs describing eighteenth-century decorative metalwork from the Canton trade.
