If you had to choose one era to represent Chinese porcelain, which would it be?

Most experts would say the Kangxi, Yongzheng, and Qianlong reigns — a span of 133 years.

This is not preference; it is a matter of fact. Craft, variety, output, innovation — all three reigns reached heights never seen before. And behind that were three forces coming together.

Porcelain is a money-burning industry. Good clay, good fuel, good craftsmen — all cost money. What costs more is the failure rate: for the finest wares, out of ten pieces fired, perhaps only one is usable.

The Kangxi, Yongzheng, and Qianlong reigns were the wealthiest period of the Qing.

Domestic peace, population growth, stable tax revenue. Silver flowed in from overseas. The single-port policy at Guangzhou produced a trade surplus that filled the imperial coffers.

More importantly: the emperors paid for porcelain out of their own pocket.

The imperial kilns of the Qing were managed directly by the Imperial Household Department. Money for porcelain did not come from state finances but from the emperor's private purse. That meant that if the emperor was willing, the budget was essentially unlimited.

An emperor willing to spend without limit — that is the most important precondition for a peak in porcelain.

Money alone is not enough. You need people who know how to fire.

In the Qing golden age, one figure was decisive: Tang Ying.

Tang Ying was the "supervisor of kilns" sent by the Imperial Household to Jingdezhen. He arrived in 1728, during the sixth year of Yongzheng, and stayed until 1756 — twenty-eight years.

What makes him unusual: Tang Ying was not a bureaucrat issuing orders from an office. He learned to paint, mix glazes, fire kilns. He crouched by the kiln with the potters. He wrote books, drew designs, personally directed the craftsmen.

Many of the signature wares of the Qing imperial kilns — imitations of Song Ru ware, imitations of Ming Xuande, painted enamels, revolving vases, trompe-l'oeil porcelain — were fired under his direction.

An emperor who trusted him, and a supervisor who understood the craft himself — that is the second precondition.

Money and people are there. The third factor is the emperor's own taste.

All three emperors — Kangxi, Yongzheng, Qianlong — were the most art-literate of the Qing.

Kangxi liked the strong, the clear, the forceful. Cowpea red and Lang kiln red, both red-glazed wares, reflect his taste.

Yongzheng liked the quiet, the refined, the inward. Yongzheng famille rose and monochromes are considered the most beautiful of the Qing. He did not like density; he liked space.

Qianlong liked the lavish, the dense, the brilliant. Revolving vases, trompe-l'oeil porcelain, layered multi-craft pieces — all from his reign. Some critics call Qianlong "vulgar", but no one can deny that Qianlong craftsmanship reached the highest technical precision in history.

Three emperors, three tastes. Together, they make a complete Qing porcelain era.

In 1795, Qianlong abdicated. The golden age was over.

What followed — Jiaqing, Daoguang, Xianfeng — declined reign by reign. In 1855, Taiping forces entered Jingdezhen and burned the imperial kilns. The imperial system essentially ended.

Porcelain is a craft that depends heavily on money, people, and taste. Remove any one and it declines.

Today, looking at Kangxi-Yongzheng-Qianlong porcelain, we sense a kind of "perfection". But that perfection did not exist by nature — it was the product of a specific historical moment.

The golden age passed, and that perfection did not return.
