Edo Kiriko is a glass craft that has been handed down in Tokyo.
In Edo (present-day Tokyo) in 1824, Kyubei Kagaya started exploring the technique of cutting patterns into the surface of glass.
Edo Kiriko was fosterd in the urban culture among the townspeople, and during the Meiji era (mid-19th century), the craft introduced not only Western equipment and instruments, but also their technique while preserving traditional techniques and has been passed down to the present time.
First of all, an expert glassblower blows clear glass into a paper-thin shape of colored glass and then rotates this in the air to make the overall form. The result is a two-layer structure with colored glass on the outside and clear glass on the inside. By cutting patterns into the outside surface with different kinds of whetstones, a vivid contrast is created between the colored glass and the transparent glass.
In 1985 Edo Kiriko was designated a Traditional Craft Industry by the Tokyo Metropolitan Government.

Edo Kiriko 江戸切子 Cut Glassware
■ Traditional Technologies and Techniques
1- Sumitsuke 墨付け (ink application) involves the use of a bamboo stick to apply ink to the surface of glassware. This preparatory process creates a basic outline of the patterns (designs) to be cut in glass.
2- Arazuri 荒摺り (rough grinding) involves the basic grinding of glass in accordance with the pattern applied to the surface using the sumitsuke process. Emery powder 金剛砂 (a grinding agent) is applied to the surface of a metal grinding wheel. This then comes into contact with the glass, and major elements of the pattern are etched accordingly. The next process 三番掛け (Sanbankake) is the application of finer grain emery powder in order to carry out more detailed pattern etching. Depending on designs, three different types of grinding wheel may be used.
3- Ishikake 石掛け (whetstone grinding) involves the use of a whetstone grinder to smooth and better define patterns etched during earlier grinding processes. Natural whetstones 丸砥石 from the southern island of Kyushu are used.
4- Kenma 研磨 (or Migaki) is the process of polishing the glass. It involves even finer-detail grinding of those surfaces that are to be non-transparent. It also brings out the traditional luster associated with transparent glass surfaces. When doing this step, polishing powder is used with a wooden polishing wheel 木車（桐、柳） (made of either Paulownia or Willow). The design is carefully polished in order to heighten both the transparency and luster of the glass.
■ Traditionally Used Raw Materials
Glass materials (crystal glass, soda lime glass)
ガラス生地（クリスタルガラス、ソーダ石灰ガラス）
■ History and Characteristics
Kiriko is a form of glass cutting in which grinders and whetstones are applied to the surface of glassware, and a number of different cutting (or grinding) techniques are employed in order to manufacture products.
The originator of the traditional craft of Edo Kiriko (cut glassware) was Kagaya Kyubei 加賀屋久兵衛, who ran a glassware store in Edo's Odenmacho 大伝馬町 (in the vicinity of modern Nihonbashi).
Kyubei is said to have learned his craft in Osaka, which at one stage was a leading center of glassware production in Japan. After completion of his apprenticeship, he returned to Edo and opened a glassware store in the city, where items such as eye glasses, thermometers and hydrometers were produced.
Edo Kiriko techniques deliver exquisite patterns that are both sparkling and lustrous when applied to suitable glassware such as "crystal glass," such techniques delivering products of great intrinsic value.
As Japan moved from the Taisho Era to the Showa Era, manufacturing evolved so quickly that "cut glass" came to be synonymous with "artistic glass," with the industry reaching its pre-war zenith around 1940.
In contemporary times, approximately 80% of Edo Kiriko manufacturing occurs in Koto and Sumida Wards.
Concerning Satsuma Kiriko 薩摩切子 (cut glassware produced in Kyushu), which is as equally loved as Edo Kiriko, it resulted from the Satsuma Domain (who ruled over modern Kagoshima Prefecture) inviting the Edo glassware manufacturer, Yotsumoto Kamejiro 四本亀次郎, to establish glassware production in the domain. This industry grew quickly as the government of Satsuma fully supported its development.

■ Traditional Technologies and Techniques
1- Glassblowing 吹きガラス:
Molten glass is spooled at the end of a blowpipe and air is blown in by mouth to shape the glass.
① Free-blowing 宙吹き:
Glass is spooled at the end of a blowpipe, air is blown into the molten glass as it is held in the air and rotated. Tweezers and other tools are used to make adjustments to the shape. The workpiece is heated in the furnace as shaping operations are repeated.
② Mold-blowing 型吹き:
In addition to the steps followed in free-blowing, a wooden or metal mold is used to shape the glass.
2- Pressed glass 型押し:
A plunger (male section) and a mold (female section) are created 雄雌の両型. Glass is spooled at the end of a blowpipe and inserted into the mold. The plunger is used to press the glass into the mold and shape it.
■ Traditionally Used Raw Materials
Silica sand, sodium carbonate, lime, potash, lead oxide, etc.
珪砂、ソーダ灰、石灰、カリ、酸化鉛等
■ History and Characteristics
1. Glass production in Japan
Glass production began in Japan during the Yayoi Period (300 BCE-300 CE). Production was discontinued for a time from the Heian Period (794-1185) to the Muromachi Period (1338-1573), before being revived following the importation of glassmaking technologies from China, Portugal and the Netherlands in the 16th and 17th centuries. Former names for glass in Japanese (currently garasu or shoshi) include ruri 瑠璃, a Japanese form of lapis lazuli; hari はり from the Chinese word boli; biidoro ビードロ from the Portuguese word vidro; and giyaman ギヤマン from the Dutch word diamant. These names also provide evidence of the overseas links that glass production in Japan enjoys.
2. Glass production in Edo (Tokyo)
Glass production in Edo is said to have started at the beginning of the 18th century, with items such as mirrors and eyeglasses produced by the first Kagaya (Minagawa) Kyubei 加賀屋（皆川）久兵衛 in the Nihonbashi-Torishiocho neighborhood. Ornamental hairpins and wind chimes were also produced by Kazusaya Tomesaburo 上総屋留三郎 in the Asakusa neighborhood. The names of Kagaya Kyubei and his son Kumasaki Yasutaro 熊崎安太郎 are included in the catalog of exhibits for Japan's First National Industrial Exhibition in 1877.
3. Cooperative association of glass producers
The Tokyo Glass [Hari] Producers Association 東京はり製造人組合 was founded in 1879. It underwent many changes over time, leading eventually to the establishment of the TOBU Glass Industry Co-operative Association of Japan (TGIA) 社団法人東部硝子工業会 in 1949. The aim of TGIA is to promote friendship, information exchange, communication and coordination among members.
4. Characteristics
Modern glass production was brought to Edo after first passing through Nagasaki, Osaka and Kyoto. In addition to items such as dishware for everyday use and bottles/jars, scientific instruments such as thermometers and hydrometers were made in response to orders from the scholar and politician Sakuma Shozan 佐久間象山 (1811-1864) as well as other people. During the early Meiji Period, glassmaking developed into one of Tokyo's local industries as modern European methods were integrated and the industry grew to meet a wide range of needs.
