Japanese Pottery Techniques

From the philosophy of wabi-sabi to the golden seams of kintsugi, Japanese ceramics traditions have shaped how the world thinks about pottery. Master potter Stephen Jepson draws deeply from these traditions — here is what every potter should know.

Wabi-Sabi — The Beauty of Imperfection

Wabi-sabi is not a technique — it is a way of seeing. It finds beauty in asymmetry, roughness, simplicity, and the natural marks of the making process. In Western pottery, perfection is often the goal — smooth surfaces, symmetrical forms, flawless glazes. In wabi-sabi, the wobble of a hand-thrown bowl, the crawl in a glaze, the slight tilt of a rim — these are not flaws. They are evidence of life.

Stephen Jepson has long embraced this philosophy in his own work. He teaches that a pot does not need to be perfect to be beautiful. In fact, the most cherished pieces in Japanese tea ceremony are often the most irregular — because irregularity invites the eye to linger and the hand to explore.

Kintsugi — Gold Repair

Kintsugi treats breakage as part of an object's history, not something to disguise. When a bowl breaks, the pieces are joined with lacquer mixed with gold, silver, or platinum powder. The repair lines become a feature — golden seams that celebrate the life of the object rather than hiding its damage.

You can practice a simplified version of kintsugi at home using food-safe epoxy mixed with gold mica powder. Traditional kintsugi uses urushi lacquer and real gold powder, which requires specialized materials, proper ventilation, and patience — the lacquer cures over weeks, not hours.

Shino Glaze

Shino is a high-fire glaze developed in the Mino province of Japan during the 16th century. It produces a warm, milky white to burnt orange surface with rich textures — crawling, pinholes, and carbon trapping where flames contact the glaze during reduction firing. Shino glazes are thick, applied heavily, and fired to cone 10-12. The results are unpredictable and beautiful, with no two pieces looking alike.

Traditional Japanese Ware Styles

Oribe Ware

Oribe pottery is named after tea master Furuta Oribe and is characterized by bold, asymmetric forms decorated with copper-green glazes and geometric painted designs. Oribe pieces often combine glazed and unglazed surfaces, with iron-painted patterns on the exposed clay. The style is playful, unconventional, and breaks the rules of symmetry deliberately.

Raku

Originally developed for the Japanese tea ceremony, raku involves removing pottery from the kiln while still glowing hot and placing it in combustible material. The rapid cooling and reduction atmosphere create metallic lusters, crackled glazes, and dramatic smoke patterns. Western raku has evolved into its own tradition, but the Japanese original remains focused on simplicity and the tea bowl form.

Anagama Wood Firing

An anagama is a single-chamber kiln fed by wood for 3-7 days continuously. Teams of potters take shifts stoking the fire around the clock. Wood ash settles on the pots and melts into a natural ash glaze — greens, browns, and golds that no commercial glaze can replicate. The flame path leaves scorch marks and color variations. Every piece is unique based on where it sat in the kiln. Stephen Jepson considers wood firing one of the most profound experiences a potter can have.

How Japanese Techniques Influence Modern Studio Pottery

Japanese ceramics have transformed Western studio pottery in fundamental ways. The wabi-sabi philosophy gave potters permission to embrace imperfection. Kintsugi inspired a movement of visible repair and upcycling. Shino and wood-fire aesthetics pushed potters toward atmospheric firing. And the Japanese reverence for the handmade object — treating a tea bowl as a work of art equal to any painting — elevated the status of ceramic art worldwide.

Applying Japanese Principles to Your Work

Studio Tip: Try throwing a tea bowl — a chawan — in the Japanese style. Use a stoneware or porcelain clay, throw a wide, slightly irregular bowl about 4 inches in diameter and 3 inches tall. Leave the foot unglazed. Apply a Shino or ash glaze thickly. The simplicity of the form reveals your skill level honestly. Stephen Jepson says the tea bowl is the most honest form in pottery — it hides nothing.

Frequently Asked Questions

What is wabi-sabi in pottery?
Wabi-sabi is a Japanese aesthetic philosophy that finds beauty in imperfection, impermanence, and incompleteness. In pottery, this means embracing irregular forms, natural textures, asymmetry, and the marks of the making process rather than striving for machine-like perfection. A wabi-sabi pot shows the hand of the maker.
What is kintsugi and can you do it at home?
Kintsugi is the Japanese art of repairing broken pottery with gold or gold-colored lacquer, treating the break as part of the object's history rather than something to hide. You can practice kintsugi at home using food-safe epoxy mixed with gold mica powder. Traditional kintsugi uses urushi lacquer and real gold, which requires specialized materials and skills.
What is Shino glaze?
Shino is a traditional Japanese glaze known for its warm, milky white to orange surface with crawling textures and carbon trapping. It was developed in the Mino province of Japan in the 16th century. Shino glazes are high-fire (cone 10-12) and create unique effects — pinholes, orange-peel texture, and areas where carbon from the kiln atmosphere gets trapped under the glaze surface.
How does anagama wood firing work?
An anagama is a single-chamber wood-fired kiln that fires continuously for 3-7 days. Wood ash lands on the pots during firing and melts into a natural glaze. The flame path, ash deposits, and atmosphere create effects that cannot be replicated in an electric kiln. Each piece is unique based on its position in the kiln.
