This 29.1-centimeter tall, 67.2-centimeter long, and 23-centimeter wide relic was unearthed from Tomb no. 1 at Yongho-dong, Dongsin-myeon, Unsan-gun, North Pyeongan Province. The center of the chamber tomb from the ancient Korean kingdom of Koguryo had already collapsed by the time Sekino Tadashi (關野貞) examined it in 1918 and the cooking stove was found where the tomb's main chamber, referred to as neolbang (玄室) in Korean, is likely to have existed.
The featured cooking stove was cast in iron and its outline resembles a miniature version of the stove in the kitchen depicted in a mural from the Anak Tomb no. 3. Instead of being directly attached to the furnace, the vent pipe is placed to the side of the furnace, a unique style identical to an earthen furnace excavated from Tonggou (通溝). The stove could have actually been used to cook, but it is generally considered to have been buried with the deceased for them to use in their afterlife.
