means Frankish. Historic forms of marbling used both organic and inorganic pigments mixed with water for colors, and sizes were traditionally made from gum tragacanth (Astragalus spp.), gum karaya, guar gum, fenugreek (Trigonella foenum-graecum), fleabane, linseed, and psyllium. Since the late 19th century, a boiled extract of the carrageenan-rich alga known as Irish moss (Chondrus crispus), has been employed for sizing. Today, many marblers use powdered carrageenan extracted from various seaweeds. Another plant-derived mucilage is made from sodium alginate. In recent years, a synthetic size made from hydroxypropyl methylcellulose, a common ingredient in instant wallpaper paste, is often used as a size for floating acrylic and oil paints. In the size-based method, colors made from pigments are mixed with a surfactant such as ox gall. Sometimes, oil or turpentine may be added to a color, to achieve special effects. The colors are then spattered or dropped onto the size, one color after another until there is a dense pattern of several colors. Straw from the broom corn was used to make a kind of whisk for sprinkling the paint, or horsehair to create a kind of drop-brush. Each successive layer of pigment spreads slightly less than the last, and the colors may require additional surfactant to float and uniformly expand. Once the colors are laid down, various tools and implements such as rakes, combs, and styluses are often used in a series of movements to create more intricate designs. Paper or cloth is often mordanted beforehand with aluminium sulfate (alum) and gently laid onto the floating colors (although methods such as Turkish and Japanese do not require mordanting). The colors are thereby transferred and adhered to the surface of the paper or material. The paper or material is then carefully lifted off the size and hung up to dry. Some marblers gently drag the paper over a rod to draw off the excess size. If necessary, excess bleeding colors and sizing can be rinsed off, and then the paper or fabric is allowed to dry. After the print is made, any color residues remaining on the size are carefully skimmed off of the surface, in order to clear it before starting a new pattern. Contemporary marblers employ a variety of modern materials, some in place of or in combination with the more traditional ones. A wide variety of colors are used today in place of the historic pigment colors. Plastic
