This jar, called a heobeok, was commonly used to draw and transport water. Each of jars could contain up to 10 doe. One doe was a traditional Korean unit of measure roughly equivalent to 1.8 liters. Normally these jars were contained in a basket-like gudeok and then carried on a person’s shoulder. The narrow mouth of the jar prevented water from spilling out. Depending on the size of the jar, people referred to them differently. For example, there are names other than heoboek such as bareut heobeok, daebaeji, and aegi daebaeji.
