📜 Origin & History

The name Sacrificial Blue comes from the natural image of 'clear sky after rain,' depicting the clear, washed-clean blue sky after a downpour. This color name encapsulates the Chinese ancients' capture of a beautiful moment in nature and their poetic naming, solidifying meteorological beauty into a color symbol.

Sacrificial Blue as a porcelain glaze was first created in Jingdezhen during the Yuan Dynasty. It is a high-temperature cobalt blue glaze, colored with cobalt like blue-and-white, but Sacrificial Blue covers the entire vessel surface with blue glaze, resulting in a uniform, deep, and bright color. Because it was used for altar sacrifices to heaven, it is also called 'Altar Blue.'

The Ming Dynasty Xuande period saw the peak of Sacrificial Blue glaze craftsmanship. Xuande Sacrificial Blue bowls had an evenly smooth glaze surface like a mirror, lustrous and bright, often decorated with gold-painted patterns, the blue and gold complementing each other magnificently. After Xuande, the Sacrificial Blue technique was lost for a time, only to be successfully revived in the Qing Dynasty Kangxi period.

In the Qing Dynasty, Sacrificial Blue glaze spawned various derivatives like 'Powder Blue' and 'Sky Blue.' Among them, 'Splashed Blue,' also known as 'Snowflake Blue,' involved blowing cobalt material onto the body through a bamboo tube, creating a blue-and-white dappled effect like falling snowflakes, a decorative technique unique to the Kangxi period.

Sacrificial Blue symbolizes the auspicious meaning of 'clouds parting to reveal the sun' in Chinese color culture. Its bright yet not frivolous blue tone retains the calmness of blue while adding a rare clarity, making it a uniquely distinctive presence in the traditional Chinese blue series.
