Ceremonial Blue Glaze ( (also known as Jiqing Blue, Jilan, or Ji Blue) was a glaze color used in the imperial kilns during the Ming and Qing dynasties. This cup, shaped like a bell, was meticulously crafted. After the porcelain was fired, artisans filled the intricate engraved patterns with 24K pure gold powder and subjected it to high-temperature firing once more. The result is a stunning piece where a crane with outstretched wings seems to emerge from the glaze, exuding a sense of dynamic movement and artistry.
