Edo kiriko 江戸切子
Edokiriko (Japanese: 江戸切子、えどきりこ) is Japanese famous glass craftwork. It was originally produced in the city of Edo which was Tokyo's name during the Edo period (1603-1868). Kiriko means "cut glass" so its name means "cut glass from the city of Edo". It is still a popular type of glass craft today, as sake glasses or other type of glasswares.
Originally, patterns were cut on a transparent and colorless glass surface. However, new techniques were introduced during the Meiji period (1868-1912), when Japan first opened its doors to the other countries after having isolated itself for over 200 years. The style of Edo kiriko made with colored glass started being produced in large quantities during this time.
Today, Edo kiriko is known for its intricate designs cut into blue, red or other colored glass. The most typical design is called nanako or fish eggs because it is composed of numerous fine straight lines that resemble round fish eggs. However, a closer look reveals the design is actually composed of many small squares arranged side by side. Other quintessential Japanese designs include plants such as chrysanthemums or hemp leaves.
