Mangdaengi is a cone-shaped clay brick whose diameter is 13cm and whose length is 25cm. Mangdaengi bricks are fire-resistant and used to make the upper part of a kiln round. A Mangdaengi kiln is composed of five to six domed rooms which are connected side by side. The rooms become larger and larger as they are located farther from the entrance of a kiln. Though it is possible for a kiln to be located on a plain, it is most ideal for a kiln to be located on a 15° slope.
There are various facilities around a kiln such as a workhouse, a treadmill, a hole for settling clay sediment, a clay refinery, and a household.
