Cut glass is technique to cut and bring down various designs using metal disk or whetstone on the surface of glass. Edo Kiriko is made by this technique. Design that graphically designed life tool of Edo including plants such as chrysanthemum or family crest of a hemp leaf and reticulate pattern, lattice is inherited as traditional design. Patterns of Edo Kiriko are created in combination to devise them. Product called "space" that put cut for transparent glass place was mainstream once, but in late years product of "color coating" (be and help put on) that cut glass which poured film of stained glass over the surface of transparent glass place becomes mainstream. Cut which worked of accent that part of color place and comparison of sight glass became clear as for the product of "color coating" is characteristic.
Kiriko is the traditional art of cutting a multitude of decorative patterns into the surface of glass using tools such as metal discs and grindstones, and is the method used to produce Edo Kiriko. Items of daily life in Edo, such as chrysanthemum and cannabis leaves, basket patterns and geometric shapes form the basis of traditionally used patterns. The unique style of Edo Kiriko is born from the incredible skill used to combine the variety of patterns into a finished piece. Originally cutting shapes into clear glass, known as the Suki or “see through” style was popular.
Recently, however, applying a film of colored glass on top of clear glass and then cutting, known as the Irokise or “color covering” style has become the mainstream. The key characteristic of Irokise pieces is the vivid contrast between colored and clear areas of glass created by the decorative cuttings.
How to make
Production process is greatly divided into four. Line becoming standard of cut on the surface of glass and "wild woodcut print" (drag fault) "to calculate, and to sharpen basics that it is likely on the surface with metal disk sumi charge account" and groove where it is to allocate point, and to mark finish design using disk of whetstone; "hang stone", and is 4 processes of "polishing" to give aspect that sharpened luster. We divide "wild woodcut print" into 2-3 phases and, depending on product, may perform. In addition, we get design that "we hang stone" and reduced by deha, "wild woodcut print" fixed and finish and begin to sharpen very small design in whetstone. In Edo Kiriko, sketch of design to reduce may not be pulled on glass surface. Traditional designs are created by experienced eyes and the expert skill.
The process of making Edo Kiriko is divided into four main steps. In the first step, “Waridashi, Sumitsuke”, the surface of the glass is marked with lines and dots in a process known as so the artisan can see where to carve. In the second step, “Arazuri”, a metal disk is used to make the initial cuts of the design.
For the third step, “Ishikake”, a whetstone is used to complete the design. After all cutting is complete, for the final step, “Migaki”, the glass is polished to a brilliant finish. Depending on the design, sometimes the Arazuri step needs to be divided into two or three stages. Additionally, in addition to completing the cuts started in Arazuri, the whetstone is used in the Ishikake step to etch delicate patterns without any initial cuts. In Edo Kiriko, all of these steps need to be completed without the aid of any rough sketch on the surface of the glass. Only the well-trained eye and the experienced hand of a master artisan of many years can bring these traditional and beautiful patterns to fruition.
