More difficult to make. Black Edo-kiriko cut glass
The Japanese cut glass Edo-kiriko has more than 180 years history. The glass wholesaler Kaga-ya Kyubei in Edo (ancient Tokyo) carved a glass from the Europe. It was the beginning of Edo-kiriko. Since then, the craftsmen of the cut glass had improved a various patterns.
And the industry started to produce a cased glass Edo-kiriko in Meiji Period (1868-1912). There are many colors of Edo-kiriko including, blue, red, green, and purple.
But still now, the black colored Edo-kiriko is most difficult to make because the Japanese cut glass is so thin (0.1-0.2mm) that black easily returns to gray with a light. Even for an expert craftsman, it takes times more time to make the black Edo-kiriko. They can only produce three special cut glass products in a day like the amber Edo-kiriko.
Thanks to the efforts of the craftsmen, the contrast and engraving of the black Edo-kiriko is clearer than other colors.
