Royal Crown Derby
Royal Crown Derby was founded in 1750 by William Duesbury, who established a small pottery factory in Derby, England.
In 1773, Duesbury purchased the Chelsea Porcelain Manufactory, which was one of the leading porcelain manufacturers in England at the time.
On this page, I will teach you how to estimate the date of manufacture. Royal Crown Derby has its own unique dating system, so we can easily learn that.
