Hold near the spinning silhouette and pull outward. Your hand sets the belly, shoulder, and neck. Starve the wall and gravity answers.
Drag or touch at any height beside the vessel to pull that part of its wall. The sliders provide an accessible alternative. Arrow keys adjust the belly while the canvas is focused.

A moon jar begins as an admission: no single pull can make it whole.
Joseon potters threw two generous hemispheres, waited for the clay to stiffen, then persuaded their rims into a marriage. The kiln preserved every difference in moisture, weight, and intention. What emerged was never a circle drawn by a compass.
Our digital wheel keeps that bargain. The upper half echoes the lower, but never copies it. Your quickest gesture becomes a lean. Your hesitation becomes a shoulder. Fire records the rest in celadon pooling and iron blush.
흠이 아니라 흔적Not a flaw. A trace.

Glaze is weather.
A thin mineral skin passes through ash, flame, and oxygen. Open a drawer to read what the surface remembers.
Snow ashRain celadonPeach blush
01Silica / the glass68.4%
The structural net. At full heat, silica turns the dry coat into a translucent skin that gathers more deeply along the seam.
02Wood ash / the flux21.7%
Calcium lowers the melting point and encourages a quiet blue-green pooling. Too much, and the glaze runs past the foot.
03Iron / the blush0.8%
A trace is enough. Where the flame steals oxygen, iron warms from grey-green toward peach, especially across a proud shoulder.
04Feldspar / the melt9.1%
Potassium and sodium join the recipe into a stable melt. Slow cooling lets its faint cloudy depth settle behind the shine.
FIRING BOOK / 93
Fire slowly. Cool slower.
The kiln climbs for ten hours, holds long enough for the glaze to level, then closes its dampers. The most important colors arrive after the flame is gone.
