汝窯青瓷 (Ru yao qingci)
The National Palace Museum in Taipei holds the world's finest collection of Song dynasty Ru ware — the most prized Chinese imperial celadon, produced for only 20 years under Emperor Huizong (1107-1127 CE) before the kiln was destroyed. Only 87 authentic Ru ware pieces are known to exist globally. Taiwan's ceramic artists, with direct access to the NPM collection, have been engaged since the 1970s in attempting to reconstruct the Ru ware glaze formula — the specific blue-gray crackled celadon described in Song texts as 'the color of rain-washed sky after a passing cloud' (雨過天青色). The reconstruction challenge is that Ru ware's color appears from a specific iron-feldspar-ash glaze combination fired in a reducing atmosphere — but the exact mineral source of the feldspar and ash is unknown, and small variations in mineral chemistry produce radically different colors.
