During the mid to late Tang Dynasty, China produced the world's earliest copper-red glazed ever, establishing itself as the pioneer of colored glazes, particularly red glazes. By the Yongle and Xuande periods of the Ming Dynasty, red-glazed porcelain was gradually refined into peerless treasures, noted for their ox-blood-red hue and dazzling brilliance. These pieces were acclaimed as "artificial gemstones," among which the Yongle red-glazed porcelain was the most celebrated, distinguished by its fine clay body and vibrant color. Later generations referred to it as "Ji Hong" (祭红).

These auspiciously symbolic vessels became beloved treasures of emperors throughout Chinese history. For royalty, nobles, high-ranking officials, and literati, acquiring a piece of red-glazed porcelain was akin to obtaining a priceless gem, cherished with utmost care. Xu Jinzhai praised it in a poem: "Like the sky clearing after rain, red as carved jade; Offered to the temple, illuminating the world with grandeur."

The firing process for red glazes demanded exceptionally high technical skill, making these pieces extraordinarily difficult to produce. As a result, they remained highly sought-after treasures for the imperial court and collectors, both domestic and international, across generations.

Among Ji Hong varieties, the crackled ice-glazed Ji Hong is an exceptionally rare treasure, now housed in the Shandong Dezhou Museum.
