What is Raku-yaki?
Raku-yaki is one of the most famous types of earthenware in Japan. ICHI-RAKU, NI-HAGI, SAN-KARATSU has been said since many years ago, which means that Raku-yaki is first, Hagi-yaki is second, and Karatsu-yaki is third of all earthenware in Japan. In short, Raku-yaki is regarded as the most prestigious and highest ranked earthenware in the tea ceremony.
Raku-yaki has a long history and is thought to have been first made about 450 years ago by Chohjiroh, who is the founder of the Raku family. It is said that Sen no Rikyuh, who is the famous tea master in the 16th century and inventor of Wabi-cha, which became the origin of the modern tea ceremony, had Chohjiroh make Raku-yaki to create the most suitable Matcha bowl for the Wabi-cha tea ceremony.
Raku-yaki is a soft-type glazed ceramic ware and it is divided largely into two types: Kuro-raku is black Raku-yaki, and Aka-raku is red Raku-yaki. Kuro-raku is the earthenware which is changed to a black color in a kiln heated at over 1000C (1832F) since the color of the iron glaze changes by reduction firing. Aka-raku is the earthenware which is changed to a red color in a kiln heated at approximately 800C (1472F) since Aka-raku is made from the clay containing ocher which is changed to red color by reduction firing.
Raku-yaki is lighter in weight than it looks due to low density. Thermal conductivity is not so high and the hand feel and texture is very comfortable and soft. Its form and size also fit perfectly into both hands when drinking Matcha. For these reasons, Raku-yaki is very suitable for drinking Matcha and tea ceremony use.
Raku-yaki is also characterized by its forming method. Raku-yaki is formed only by hand and spatula with the clay on a pallet, while most earthenware is made using an electric potter's wheel or kicking potter's wheel. There is a limit to the depth that can be produced by hand (the hollow of the hand). You will be attracted to the originality and uniqueness of works produced in this limited cubic volume.

The History of the Raku Family - Pedigree Potter of Raku-yaki
In the 16th century, Cha-no-yu traditional tea ceremony was regarded as a status symbol and as a way to enhance a sense of presence as an upper-class cultural value. Sen no Rikyuh, who was an attendant of the ruling class in Japan, asked Chohjiroh, a tile-maker at that time, to produce Raku-yaki to create the most suitable Matcha bowl for tea ceremony. Raku-yaki was born specifically to serve Matcha and aesthetically designed to embody Wabi-cha, which is the style of tea associated with the aesthetic sense of rustic simplicity, perfected by Sen no Rikyuh.
Raku-yaki was initially called Ima-yaki, which means "now ware" in Japanese since it was quite avant-garde and novel at that time. Raku-yaki was subsequently renamed Juraku-yaki due to the fact that the Raku home was nearby the Jurakudai palace and also Sen no Rikyuh lived inside the premises of the palace. Juraku-yaki was eventually abbreviated as Raku-yaki.
Since the age of Chohjiroh, the founder of Raku-yaki, the tradition of Raku-yaki has been handed down across successive generations to the present head, 15th generation Kichizaemon. For more than 450 years, successive generations have passed down the technique and tradition of Raku-yaki without any modification. The methods have remained the same since the birth of Raku-yaki. However, it is thought that the tradition is not only to follow in the footsteps of predecessors, but to build upon the history of the Raku family and to innovate. Each generation’s goal was to produce avant-garde and novel works to surpass their predecessors. Therefore, excellent and remarkable works were successively produced and the great tradition remains.

What is Shouraku / Kirai-kiln?
In 1995, Teruo Sasaki, who was the third potter of Shouraku Kiln, opened a kiln under the name of "Kirai" and the name of "Kyoshitsu" which was given by the fourteenth chief administrator of Daitokuji temple*, Settei Fukutomi Roushi master.
The Sasaki family is well-known for their traditional Raku-yaki at Shouraku Kiln. Shouraku Kiln opened in 1903, and is one of the most traditional Raku-yaki kilns in Kyoto. Yamato Sasaki, who is the son of Teruo Sasaki and the fourth head of Shouraku Kiln, succeeded to Kyoshitsu the second in 2011.
Kirai Kiln produces avant-garde and novel works which are not restricted by traditional style, while still adhering to traditional Raku-yaki techniques. Shouraku Kiln, on the other hand, strictly follows the footsteps and traditional methods of Raku-yaki.
(*) Daitokuji temple was erected in 1325. The temple has had a great influence on Japanese culture and Cha-no-yu traditional tea ceremony, since the spirit of Cha-no-yu is based in Zen philosophy. It is also said that Juko Murata or Sen no Rikyuh, who is the famous tea master and pioneer of the tea ceremony, maintained close relations with Daitokuji temple.

Manufacturing Process of Raku-yaki at Shouraku / Kirai-kiln
Pugging process
Raku-yaki was born in the city center of Kyoto. General earthenware, on the other hand, was born in the region which produced clay suitable for earthenware. Raku-yaki is produced only for Cha-no-yu traditional tea ceremony, unlike general earthenware, which developed as an industry. For this reason, it can be said that Raku-yaki is a highly cultural art.
Clay is ordinarily mixed by machines, however to create excellent works like one-of-a-kind Raku-yaki, the clay is mixed by hand to avoid fluctuation in quality. Even skilled craftsman can produce only about 8kg of mixed clay by hand. The machines, on the other hand, can produce about 200kg of it at the same time.
It is said that it takes more than three years to acquire pugging skill. The clay is allowed to rest for about one week after mixing.

Forming process
Raku-yaki is formed by hand without using the potter's wheel. The forming method is called TEDUKUNE. The earthenware created by TEDUKUNE is not seen in representative Japanese earthenware except for Raku-yaki. Skilled craftsmen can determine the weight of one piece only by hand, not using a scale.
Unlike ceramics mass produced by industrial machines, craftsmen following the TEDUKUNE method can ensure that each piece has a desirable hand feel and texture as they create each work individually by hand. This makes it possible to create the excellent Matcha bowl which is most suitable for tea ceremony. Since there is a limit to the depth that can be produced by hand (the hollow of the hand), to express originality and uniqueness in the limited cubic volume is the main attraction and aesthetic of Raku-yaki. Raku-yaki is also ordinarily formed asymmetrically and the rim is also not flat but uneven due to TEDUKUNE forming. The unique shape clearly indicates the characteristics of genuine Raku-yaki. It is thought that the characteristics are the foundation of the Cha-no-yu tea ceremony and reflect the Japanese aesthetic.
After drying for about three days, the base called KOHDAI is attached to the bottom of the bowl by using adhesive clay. This is a very difficult and delicate process even for skilled craftsmen since the KOHDAI can easily separate from the bowl during firing in the kiln if it is insufficiently attached. Next, the bowl is trimmed, after drying about three days to one week.

Trimming process
Trimming is one of the most important processes to determine the quality of works. It is said that it takes more than ten years to learn to produce even a practice Matcha bowl, not for tea ceremony. Each craftsman owns several original trimming tools like a metal spatula and trims the works using the optimal one. Not only the surface but also the inside of the bowl is trimmed and each hollow called CHAKIN-ZURE, CHASEN-ZURE and CHA-DAMARI* is formed by trimming. These are features of traditional Raku-yaki. While considering the usability and thickness of the glaze, the craftsmen carefully scrape. This is also a difficult and delicate process since the bowl can easily break if an area was milled too much. Craftsmen shape the works imagining the final form.
(*) CHAKIN-ZURE means the point where cloth used in the tea ceremony rubs, CHASEN-ZURE means the point CHASEN Bamboo Whisk rubs, and CHA-DAMARI means tea pool in Japanese. CHAKIN-ZURE is the curved place near the rim, CHASEN-ZURE is the curve inside the bottom of the bowl, and CHA-DAMARI is the bottom point in which CHA tea gathers.

Glazing process
Earthenware is not glazed only one time but overglazed four to five times over a period of days. This process creates the ideal surface texture and produces elegant and graceful works.
Transparent glaze is used for Aka-raku red Raku-yaki unlike Kuro-raku, since the red color of Aka-raku appears from the clay, which contains ocher, itself. Thus, to enjoy the noble and excellent red color becomes possible.

Firing process
After about one minute, which is required to melt the glaze, Kuro-raku which is red hot due to high temperature is taken out from the kiln. The glaze sets at the moment it is taken out from the kiln, and the track of the tongs used to remove the hot Raku from the kiln, called YATTOKO-ATO, remains on the inside and outside of the bowl. This is proof of genuine Raku-yaki produced by traditional Raku-yaki methods. Kuro-raku is commonly fired in the gas kiln, which is burning since it is colored by reduction firing.
Aka-raku, on the other hand, is created by firing in a kiln heated to about 800C (1472F). Aka-raku is commonly fired in an electric kiln which is not burning since it is colored by oxidation firing. Thus, noble and excellent red color is created from the clay itself.
KANNYU, cracking patterns on the surface, is one of the main features of Aka-raku. The KANNYU cracks form a lattice, the size and spacing of which are determined by the timing of cooling in water. If the bowl is quickly imbibed in water just after removal from the kiln, the size of the KANNYU lattice is finer than one cooled slowly. A skillful craftsman will judge the right timing for the work by only the sound of cracking.
