Answer 1

The Royal Crown Derby Porcelain Company is a porcelain manufacturer, based in Derby, England. The company, particularly known for its high-quality bone china, has produced tableware and ornamental items since approximately 1750.

Bone china is a type of porcelain body first developed in Britain in which calcined ox bone (bone ash) is a major constituent. It is characterized by high whiteness, translucency and strength.

English manufacturers were keen to produce porcelain of the quality to be found in Chinese imports, but they had to go down a different route. It undertook further developments, and subsequently popularized it, by mixing it with kaolin and China stone to compete with the imported Oriental porcelain.
