Urushi-e woodblock prints were made using thick, dark black lines, and were sometimes hand-colored. The ink was mixed with an animal-based glue called
nikawa, which thickened it and gave it a lustrous shine, said to resemble lacquer. Most often, this was used not in creating the entire print, but only in enhancing a particular element, such as an
obi or a figure's hair, to give it shine and make the image more luxurious overall. Prints which include
urushi-e elements are likely to also feature the use of
mica, metal dusts, and other elements which enhanced the appearance, quality and value of the works. The technique was most popular in the early 18th century Japan during the Edo era and can be seen in works by many artists of the time. == Paintings ==
