Oegosan Onggi Village

Onggi are the large earthenware jars that stand on Korean roof terraces holding soy sauce, doenjang and kimchi, and the reason they matter technically is that they breathe: coarse clay with sand and organic matter fired at moderate temperature leaves the wall micro-porous, so air passes but liquid does not, which is what lets a fermentation continue for years without spoiling. Oegosan is where the trade concentrated - potters displaced in the 1950s settled here for the clay and the fuel, and at its height dozens of workshops ran. Several remain, along with a museum and the long climbing kilns that fire them. Potters throw the big jars by a coiling-and-beating method rather than on a wheel alone, which is worth watching if a workshop is in production. There is an onggi festival in spring. It is a working village, not a reconstruction, so what you see depends on the day.

What you actually see

• The working workshops - coiling and beating the large jars.
• The climbing kilns - long wood-fired kilns on the slope.
• The museum - how the porous wall makes fermentation work.
• The jar yards - stacked onggi across the village.

When to go

April to June and September to November; the onggi festival is in spring. Weekdays are when the potters actually work - at weekends you may find the workshops closed.

Honest expectations

It is a small working village, not a themed attraction, and on a quiet day there may be little activity. English information is limited. Buying a full-size jar is impractical to carry.
