uneven, globular body. The footrim is free of glaze, and the
base is glazed.

Crackles, networks of small cracks in the glaze, are caused by
the quick cooling of the kiln after firing. The glaze shrinks

causes it to crack. This feature, which can be induced, is
usually accidental in ceramics made in Korean kilns. The
dark brown color of the crackles on this jar was caused by
staining from use.
