Marbling

The art of marbling paper is very old. Unfortunately, like many historical facts involving paper, no one is exactly sure how old it is. Paper doesn't tolerate the ravages of time like stone or metal. However, historians agree that the technique of marbling has been making paper exceptionally beautiful since 10th century Japan.
Marbling originated in Japan in around the twelfth century. Some believe it was discovered by accident by someone in the Japanese imperial family who submerged sumi ink paintings in water, watched the inks float to the surface, then put a piece of paper on the floating ink, lifted it up and preserved the image.
