A WHITE PORCELAIN SQUARE BOTTLE
JOSEON DYNASTY (18TH CENTURY)
The square bottle set on square foot with angled shoulders and
tapered, straight cylindrical neck ending in a rolled rip and decorated
with a lustrous transparent glaze with blue cast
6¿ in. (15.6 cm.) high
$120,000-160,000

For another bottle of this type, see The Radiance of Jade and
Clarity of Water: Korean Ceramics from the Ataka Collection,
exh. cat. (Chicago: The Art Institute; New York: Hudson Hills
Press, 1992), pl. 73. The catalogue entry remarks that scholars have
not determined the exact procedure the Joseon potter followed
for square porcelain bottles. One theory holds that he used four
individual molds to form each side, pressed them together and then
added the top and base. Another holds that the potter molded the
clay into a dense cube that he hollowed out.
