François Xavier d'Entrecolles

[2] D'Entrecolles sent back to Father Orry, S.J., Procator of the Jesuit missions in China and the Indies, a detailed, very comprehensive and well-structured letter to communicate his findings:[2] "From time to time I have stayed in Ching-tê-chên to administer to the spiritual necessities of my converts, and so I have interested myself in the manufacture of this beautiful porcelain, which is so highly prized, and is sent to all parts of the world.

[4] D'Entrecolles also wrote letters about how the Chinese raised silkworms, and manufactured artificial flowers and synthetic pearls, and practised oral vaccination against smallpox.

Citations required, Chinese exports of porcelain soon shrank considerably, especially by the end of the reign of the Qianlong Emperor.

[10] Josiah Wedgwood, the famous English porcelain manufacturer, is known to have copied extracts of d'Entrecolles' work in his Commonplace Book.

[10] D'Entrecolles' work was also reproduced, without attribution, in Malachy Postlethwayt's widely influential Universal Dictionary of Trade and Commerce (1757–74).
