Bottle Cranging from brownish-olive to a bluish-green, this rel-
12th–13th century, Goryeo atively heavily potted bottle has a dish-shaped mouth above
TL results: fired between 600 & 1,000 years ago a neck that spreads onto slumping and rounded shoulders,
Stoneware with celadon glaze tapering slightly, and ending with a broad base. The base and
H: 25.5 cm, W: 14.6 cm footrim are glazed. Three scars left by the clay pads on which
the bottle was fired can be seen on the base and footrim.
There are also remains of kiln grit on part of the footrim. The
exposed areas of the body that were not originally covered
with glaze oxidized a reddish color, though the unexposed
body material is actually gray.

In order to fire a celadon glaze of even and ideal color, a
subtle bluish or grayish-green, the wares must be fired in a
well-controlled reduction atmosphere, meaning the process
by which oxidation is prevented by the removal of oxygen
within the kiln. If the atmospheric conditions are not kept
consistent within the kiln, the glaze color will become un-
even, such as on this piece.
