Onggi: The Everyday Korean Pot Made to Be Used
How clay preparation, hand-built walls and careful firing turn Korea’s familiar earthenware vessels into a craft worth looking at closely.
A good way to begin looking at onggi is to ask what a pot was made to do. Hold grain? Store a sauce? Pour a drink? The familiar rounded Korean earthenware jar belongs to a much wider family of household objects, including lamps and brush holders. Its appeal starts with that closeness to everyday life.

For anyone encountering Korean craft through museums, markets or a single cup at home, onggi offers an approachable subject. You do not need to recognize a dynasty or a famous signature. Start with the opening, follow the curve of the shoulder, and imagine the hands required to give the vessel its shape.
The work begins before the wheel
Korea.net's illustrated series, produced with the National Research Institute of Cultural Heritage, documents the preparation behind traditional onggi. Clay is wetted and, where necessary, strained to remove unwanted material such as stones and roots. Cutting, pounding and kneading follow before the potter prepares the clay for building. The apparently straightforward brown vessel begins with decisions about the material itself. Preparing the clay
That background changes a useful viewing question. Instead of asking only whether a pot is perfectly symmetrical, ask how its maker controlled such a large quantity of soft clay. A broad body and a relatively narrow mouth present different demands. Even before decoration, the outline tells a story of construction.
Follow the wall upward
The same research series describes a base-first process, followed by the body and then the mouth. Its documented approaches include building with successive rope-like strips, spiraling a long coil, and assembling walls from slabs. Large vessels are shaped with tools as well as hands. These are specific traditional methods, rather than a claim that every contemporary workshop follows an identical recipe. Shaping an onggi vessel
Tools make the process easier to read. The institute's survey shows implements for measuring height and width, shaping the walls, trimming surfaces and finishing the mouth. It also records equipment for carrying fragile, unfired pots. Looking at the finished object, pay attention to the rim and to changes in the body's curve: they are places where handling, balance and use meet. The potter's tools
The kiln is part of the craft
Shaping is only one stage. In the traditional firing documented by the institute, heat rises gradually to remove moisture before the hotter phase; after firing, the sealed kiln cools over several days. Both the build-up and the cooling matter. The craft therefore includes managing a whole kiln of vessels, with considerable time between the last shaping gesture and the finished pot. Firing and cooling
Onggi also includes more than one surface treatment. The series separately describes unglazed jilgeureut and its different firing arrangement. A glossy brown finish is an immediately recognizable image, but it should not become the only visual test of the tradition. Unglazed earthenware
Bring the questions into everyday life
Contemporary makers continue to work beyond the large storage jar. The Korea Foundation describes cups, pitchers, dishes and vases adapted to modern homes. In March 2026, the Korean Cultural Center Washington, D.C., announced a program with ceramic artist Yeonsoo Kim exploring onggi's movement from practical storage into contemporary art. That April event is past; its framing is a useful reminder that a living craft keeps acquiring new forms. Korean Cultural Center
If you are choosing a piece, ask who made it, what it is intended for and how the maker recommends caring for it. Confirm food use and heating or dishwasher suitability for that particular object. A decorative jar and a working kitchen vessel can invite different expectations.
The photographs here are archival, including a 1952 image and two views from December 2012. For a closer look at hands and movement, Goldmark Gallery's 2014 film follows Lee Kang-hyo constructing monumental pots. Watch the way he builds volume, then return to the smaller objects around you. An ordinary vessel can reward a very careful look. The filmmaker's introduction
