Joseon Moon Jar — Content Slide

Two halves, joined at the middle

Thrown in upper and lower halves, then luted at the equator — the seam is kept, never hidden.

Fired above twelve hundred

Iron-free kaolin in a reduction kiln past 1250°C turns milk-white glaze faintly celadon in raking light.

Imperfection held on purpose

The silhouette sags a little to one side; the join never lines up perfectly — that unevenness is the jar.

Shown against the dark

Museums set each jar on a charcoal ground so the milky bluish glow reads — the only honest way to see it.
