"The technique of marbling paper was developed in Asia (the oldest examples, from Japan, have been dated to the 12th century) before travelling west, to Persia, Turkey, and Europe. The decoration is achieved not directly onto the sheet of paper itself, but on a liquid called the marbling ‘size’ (‘a glutinous or viscid wash applied to paper, parchment, etc., to provide a suitable ground for gilding, painting, or other work’, OED). Marbling paints are then sprinkled onto the size, in a flat tray, where they can either be left to float, or be manipulated with tools such as needles or combs to produce the decoration desired; the paper is then laid onto the size and the pattern thus transferred onto the paper."
