Kwak Kyungtae

Onggi Masterclass

2nd - 6th September 2026 | 5 Day Workshop | £2,300

This five-day masterclass offers a taste of traditional Korean Onggi-making techniques for making large jars. Neither a wheel throwing method nor a pure hand building method, Onggi involves a unique set of techniques that allow the maker to create a jar of any scale.

What is Onggi?

Onggi has been popularised as Korea’s ‘large fermentation vessels’, but its meaning is not limited to large vessels. We explore how ‘Onggi’ encompasses a way of working with certain types of clay and with certain firing conditions. In this intensive session we uncover the deep roots of onggi in Korean society and its role as a vessel for humanity, both literally and figuratively. We begin by exploring how specific cultural, geographical, and culinary contexts informed the development of this incredible set of techniques, then dive right into making. As Teacher Kwak Kyungtae forms an Onggi from start to finish, his apprentice will be translating his detailed commentary on each part of the process. One of the beautiful aspects of Onggi is that each movement has been developed and refined by generations of potters; you will witness the same movements that were being used thousands of years ago.

WHAT YOU NEED TO KNOW

The Course in Detail

In this intensive multi-day masterclass master Kwak Kyungtae aims to share and teach the traditional Korean Onggi making techniques in a concise format. Onggi is a method for making large pieces quickly and efficiently, born out of the folklife necessities of Korea – used for all sorts of functional purposes like culinary fermentation, food storage, and general containers for daily life.

Many ancient traditions share similar approaches to making large jars from clay, but the Korean Onggi techniques are perhaps the fastest and most elegant collection of skills for making large jars that are still practiced today. Neither a wheel throwing method nor a pure hand building method, Onggi requires a unique set of techniques that, although difficult to learn, allow the maker to create a jar of any scale with the highest efficiency of movement.

Students will learn and study each step in this beautiful process from stretching the clay into coils (taryeom), making the base (ba-dak), coiling up the wall (taryeom-jil), to the paddling (surae-jil), shaping, rim making, etc. We will also discuss traditional glaze and firing methods for this type of ware.

This course welcomes those who desire to make larger work but may be intimidated by throwing large on the wheel. For those who have tried, or currently use, hand building in their work, but desire a fresh set of skills, a faster workflow or want to diversify their skillset, this course is for you.

No matter how many days or decades of experience you have, you will find Onggi to be a new and fulfilling learning experience that connects you further with clay as a medium. The direct contact with the clay and forming methods will awaken in you an ancient feeling of connection as each of these motions and techniques have been practiced unchanged for thousands of years, and passed down through generations.

Each student will have their own dedicated workspace and will receive plenty of individual attention from teacher Kwak and his team. There will be opportunities for students to discuss their work with their fellow students and on a one-to-one basis with teachers.

Please note, there will be an additional firing charge for final pieces. Please see our Student Contract here for details.

Topics Covered

  • Regional influences, i.e how geographical limitations influenced subtleties of form and making techniques

  • Clay sourcing, storage, and preparation for making onggi, historical and contemporary approaches

  • Practical method to stretch coils (Taryeom) on the table from a block of clay

  • Making the base disc and compressing it flat with the pang-mang-i (wooden striking tool)

  • Coiling process (Taryeom-jil), simultaneously attaching the coil and creating height in the wall of the piece in a rhythmic set of micro techniques that become one collective movement

  • Paddling the form (Surae-jil) using wooden tools inside and outside to compress, thin, and shape the form on the wheel

  •  Final Shaping (Geun-gae-jil) using metal rib tools for smoothing the surface while altering the line of the final form. 

  • Rim forming and refining using a traditional long shammy cloth (Jeon-tae) 

  • Scribing of lines and decorative motifs, historical significance and their role in accentuating form

  • Lifting the freshly made onggi off the wheel with traditional cloth method

  • Teacher Kwak’s interpretation of traditional onggi techniques in his artistic practice, along with an invitation to using traditional tools and techniques to inspire new ways of thinking and working

ARTIST STATEMENT

Kwak Kyungtae

A fascination with large Onggi vessels and the rough simplicity of Korean slipware led Kwak Kyungtae to develop his own voice in clay. He works exclusively in Onggi and Buncheong, taking his inspiration from the traditions of the Korean peninsula of his birth, particularly during the Joseon dynasty, and applying them in a modern context. His work is resonant of nature’s forms and structures through wheel-thrown and altered work, often including spontaneous marks and gestural brushwork on large pots. His works evoke a balance of the crude and the sublime power of nature’s imperfection, in large and small scale work. The austerity of his style is born from an honest, tacit relationship with clay developed and mastered over a lifetime. He has held solo and group exhibitions throughout East Asia and Europe. His pieces are sold in galleries and shops in Europe, Asia, and the USA.
