Mazarine Blue is a dark blue color that was prominently used in the decorative arts, especially in the ceramic works of the Chelsea and Derby porcelain factories. This color, also referred to as mazarin, mazareen, or mazarine blue, was a notable feature in 18th-century European ceramics. Despite its frequent use, the origins of the name “mazarine” remain unclear.

Usage in Chelsea and Derby Porcelain
Chelsea and Derby were two significant English porcelain manufacturers in the 18th century, known for their high-quality and artistically decorated ceramics. The use of Mazarine Blue as a ground color was a distinctive feature of their wares.
- Chelsea Porcelain Factory: Operating from around 1743 to 1784, Chelsea porcelain is celebrated for its rich colors and elaborate designs. Mazarine Blue was often used as a background color for intricate floral patterns and gilded decorations.
- Derby Porcelain Factory: Established in 1750, the Derby factory continued the tradition of fine porcelain production. Like Chelsea, Derby pieces also utilized Mazarine Blue to provide a striking contrast to their decorative elements.
Characteristics of Mazarine Blue
Mazarine Blue is a deep, rich blue that can vary slightly in hue but generally maintains a consistent darkness. This color was achieved through the use of cobalt oxide, a common ingredient in blue ceramic glazes.
- Visual Appeal: The depth and intensity of Mazarine Blue made it an excellent background color for highlighting the intricate details and vivid colors of overlying decorations.
- Durability: The cobalt-based glaze was not only visually appealing but also durable, withstanding the high temperatures of the kiln without losing its vibrant color.
The Mystery of the Name
The exact reason behind the name “mazarine” remains unknown. Several theories have been proposed:
- Cardinal Mazarin: Some suggest the color might be named after Cardinal Mazarin, an influential French statesman in the 17th century. However, there is no direct evidence linking him to this particular shade of blue.
- Mazarin Bible: Another theory connects the name to the Mazarin Bible, one of the earliest printed books. The rich blue binding of some editions might have inspired the name, but again, this is speculative.
- Etymology: The term “mazarine” could also be derived from an older, now obscure term related to the dyeing and textile industry, but historical records are inconclusive.
Conclusion
Mazarine Blue remains an important color in the history of decorative arts, particularly in the context of 18th-century English porcelain. Its deep, vivid hue provided a perfect canvas for the detailed and colorful designs of Chelsea and Derby ceramics. Despite the mystery surrounding its name, Mazarine Blue continues to be celebrated for its beauty and historical significance.
