Blue-and-white porcelain is a type of ceramic that features a distinctive blue decoration on a white background. This style originated in China during the Tang Dynasty (618-907 AD) and became highly popular during the Ming Dynasty (1368-1644). The blue color is typically achieved using cobalt oxide, which is painted onto the porcelain before it is glazed and fired. This porcelain is known for its intricate designs, often depicting scenes from nature, mythology, or daily life. It has been widely exported and influenced pottery styles in various cultures, including Europe and Japan. Today, blue-and-white porcelain remains a sought-after collectible and is celebrated for its beauty and craftsmanship.
