Why the line matters more than the colour

The first bowl I was allowed to engrave took eleven days, and the master rejected it on the twelfth. Not for the colour — the cinnabar had cured into the deep, lit red we wanted — but because two of my incised contours had drifted a hair too wide near the rim, where the zodiac figures bend around the curve.

The groove holds the meaning

Each scene is cut into the cured lacquer with a fine stylus, then the grooves are rubbed full of pigment, sealed, and polished back until only the line keeps the colour. A flat field of vermilion is just paint. The figure only reads because the hairline carries it — orpiment yellow, indigo-green, oxblood — one buried channel at a time.

“We don't paint the image onto the black. We cut the black away until the image has nowhere left to hide.”
