Findings from the kiln report

The whiteness is never white — it is a pale light held in clay.

SAMPLED 62 vessels surface readings
Pale celadon-blue-grey 청자빛 회백 — celadon shift in raking light 38.0 pct
Warm milk-white glaze 유백 — iron-free kaolin body 31.2 pct
Buff blush toward the foot 담황 — kiln-reduction warm zone 17.8 pct
Iron-ash shadow at the seam 철쇠 — visible join, two halves 13.0 pct

Across 62 surveyed vessels, no single “white” covers more than a third of the surface. The moon jar is a composite of cooler and warmer whites — what reads as purity is, in fact, a quiet argument between four temperatures of light.
