Onggi Kilns |
Onggi Kilns are classified into traditional Battery Kilns and improved Partition Kiln.
Battery Kilns are named because the kilns resemble batteries. They have no partition inside the kiln and the furnace is open up to the chimney so the heat can penetrate through it. The firing of the flames varies greatly according to time and temperature, so high-quality Onggi can be produced when the vessels are properly fired.
However, when the temperature is not well-controlled, the vessels are either over-fired or under-fired to frequently damage all Onggi contained in a furnace. Also, much wood was needed to heat the furnace.
To improve these setbacks, Deok-Man Heo who was producing Onggi at Gosan-ri, Ulsan developed Partition Kiln in around 1957. Partition Kiln is composed of several partitioned chambers and each chamber has holes though which the flames can pass.
When the furnace is fired, the flames pass the holes to travel through the chambers. Therefore, even when the firing is unsuccessful, each chamber acts separately to damage one chamber. Therefore, it is very economically efficient.
Onggi Village still preserves last nine Partition (Noburi) Kilns of Korea. By inducing modern-style steel-frame kilns, Onggi Village is trying hard to revitalize the Onggi culture by producing variety of products harmonizing the traditions and modernity.
