The pottery of Daegaya is different from that of Silla in terms of its form, pattern and color. The most typical pottery of Daegaya was discovered in the Jisan-dong Mounded Tomb Group and its kind is also diverse.

This includes: cylinder-shaped pottery stands, bowl-shaped pottery stands, loop-shaped pottery stands, long-necked jars, short-necked jars, flat pottery, small pottery with handle and leg, bowls with ear and leg, cups with ox horn-shaped handle and gourd-shaped pottery.

The potteries called the Goryeong style or the Daegaya style have several distinct characteristics. Their characteristics are as follows: dense wave line pattern, nipple-shaped or button-shaped handle with cover, windowed hill of mounted cup, pottery style with soft beauty of curved lines and plumpy sense of stability, and cylinder-shaped pottery stand for funeral ceremony.

The distribution area of the Goryeong style pottery was confined within the Goryeong basin until the fourth century. In the early fifth century, the distribution area was enlarged into the whole Daegaya area, including Hapcheon, Geochang, Hamyang, Namwon and Jangsu.

In the early sixth century, it was expanded into other Gaya regions, such as Goseong, Haman, Gimhae and Changwon. The expansion of the distribution area shows both the development process of Daegaya and growing influence it has.
