LARGE JAR, Ko-Echizen, Muromachi Period（1336–1573CE）

A large jar of Ko-Echizen ware from the Muromachi period.

This is a substantial jar, approximately 42 cm in both height and body diameter, presenting a dignified form with a generously rounded belly and a slightly flaring rim. There is a pronounced sense of volume from the shoulder to the body, and when set on a wooden floor or earthen surface, the clay’s elemental presence characteristic of Ko-Echizen quietly emerges.

A cross-shaped kiln stamp is incised on the shoulder. At medieval kiln centers such as Echizen, Tokoname, and Shigaraki, jars and storage vessels were often marked with such stamps, and this piece similarly reflects the production character of that period.

The two-tiered appearance formed by the exposed clay and natural glaze is the principal attraction: on the upper section, ash deposited in the kiln has melted and flowed as a natural glaze, showing hues from yellow-brown to greenish-brown. By contrast, the lower part of the body reveals a broad expanse of reddish-brown clay, layered with years of abrasion and adherent deposits. The juxtaposition of the fire-affected upper zone and the raw clay below produces the strong, distinctive character typical of Ko-Echizen large jars.

Echizen ware, regarded as one of the Six Ancient Kilns of Japan, comprises medieval ceramics produced chiefly as utilitarian vessels—jars, large storage jars, mortars, and similar forms. Rather than applying glaze intentionally, ash falling in the kiln creates natural glaze effects through the interaction of fire and clay. This piece likewise reveals the uncontrived, generous charm of the medieval kiln’s firing.

Placed in an entranceway, an earthen-floored area, or any generous space, it is particularly striking when used to display large branch arrangements. The jar itself has a substantial presence, so even bearing a single branch will bring focus and definition to the surrounding space.

An inspection in which the jar held water for approximately one hour revealed no leaks. However, being an antique large, high-fired, unglazed stoneware jar with natural ash glaze and an exposed clay surface, the vessel may gradually seep water if left filled for extended periods. When used as a flower vessel, it is advisable to insert a liner or otherwise protect the surface on which it is placed.

Because of the shape of the base, the piece is slightly unstable when empty. When filled with water its weight provides stability; if the surface on which it rests or the possibility of vibration is a concern, use protective padding such as felt to make adjustments.

Owing to its age, the rim bears chips, the body shows wear and abrasion, and there are firing marks, iron staining, flaking of the natural glaze, and encrusted deposits. There is no significant damage that alters its overall form; it retains a powerful presence as a Ko-Echizen large jar.
