Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other stone. The patterns are the result of color floated on either plain water or a viscous solution known as size, and then carefully transferred to an absorbent surface, such as paper or fabric. Through several centuries, people have applied marbled materials to a variety of surfaces. It is often employed as a writing surface for calligraphy, and especially book covers and endpapers in bookbinding and stationery. Part of its appeal is that each print is a unique monotype.
There are several methods for making marbled papers. A shallow tray is filled with water, and various kinds of ink or paint colors are carefully applied to the surface with an ink brush. Various additives or surfactant chemicals are used to help float the colors. A drop of "negative" color made of plain water with the addition of surfactant is used to drive the drop of color into a ring. The process is repeated until the surface of the water is covered with concentric rings.
The floating colors are then carefully manipulated either by blowing on them directly or through a straw, fanning the colors, or carefully using a human hair to stir the colors. In the 19th century, the Kyoto master Tokutaro Yagi developed a method for using a split piece of bamboo to gently stir the colors, resulting in concentric spiral designs. Finally, a sheet of washi paper is carefully laid onto the water surface to capture the floating design. The paper, which is often made of kozo (Paper Mulberry or Broussonetia papyrifera), must be unsized, and strong enough to withstand being immersed in water without tearing.
Another method of marbling more familiar to Europeans and Americans is made on the surface of a viscous mucilage, known as size or sizing in English. This method is commonly referred to as "Turkish" marbling, although ethnic Turkic peoples were not the only practitioners of the art, as Persian Tajiks and people of Indian origin also made these papers. The term "Turkish" was most likely used as a reference to the fact that many Europeans first encountered the art in Istanbul.
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 sized-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 ebru and Japanese suminagashi 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 broom straw can be used instead of broom corn, as well as bamboo sticks, plastic pipettes, and eye droppers to drop the colors on the surface of the size. Ox gall is still commonly used as a surfactant for watercolors and gouache, but synthetic surfactants are used in conjunction with acrylic, PVA, and oil-based paints.
History in East Asia 
An intriguing reference which some think may be a form of marbling is found in a compilation completed in 986 CE entitled 文房四谱 Wen Fang Si Pu or "Four Treasures of the Scholar's Study" edited by the 10th century scholar-official 蘇易簡 Su Yijian (957-995 CE). This compilation contains information on inkstick, inkstone, ink brush, and paper in China, which are collectively called the four treasures of the study. The text mentions a kind of decorative paper called 流沙箋 liu sha jian meaning “drifting-sand” or “flowing-sand notepaper" that was made in what is now the region of Sichuan (Yijian 4: 7a-8a).
This paper was made by dragging a piece of paper through a fermented flour paste mixed with various colors, creating a free and irregular design. A second type was made with a paste prepared from honey locust pods, mixed with croton oil, and thinned with water. Presumably both black and colored inks were employed. Ginger, possibly in the form of an oil or extract, was used to disperse the colors, or “scatter” them, according to the interpretation given by Dr. T.H. Tsien. The colors were said to gather together when a hair-brush was beaten over the design, as dandruff particles was applied to the design by beating a hairbrush over top. The finished designs, which were thought to resemble human figures, clouds, or flying birds, were then transferred to the surface of a sheet of paper. An example of paper decorated with floating ink has never been found in China. Whether or not the above methods employed floating colors remains to be determined (Tsien 94-5).
Su Yijian was an Imperial scholar-official and served as the chief of the Hanlin Academy from about 985-993 CE. He compiled the work from a wide variety of earlier sources, and was familiar with the subject, given his profession. Yet it is important to note that it is uncertain how personally acquainted he was with the various methods for making decorative papers that he compiled. He most likely reported information given to him, without having a full understanding of the methods used. His original source may have predated him by several centuries. Until the original sources that he quotes are more precisely determined, can it be possible to ascribe a firm date for the production of the papers mentioned by Su Yijian.
墨流し suminagashi, which means "floating ink" in Japanese is the oldest method of decorative paper made with floating colors that is known today. Author Einen Miura states that the oldest reference to suminagashi papers are in the waka poems of Shigeharu, (825-880 CE), a son of the famed Heian era poet Narihira (Muira 14). Various claims have been made regarding the origins of suminagashi. Some think that it may have originally come from China (Wolfe 6). Others have proposed that it may have derived from an early form of ink divination. Another theory is that the process may have derived from a form of popular entertainment at the time, in which a freshly painted sumi painting was immersed into water, and the ink slowly dispersed from the paper and rose to the surface, forming curious designs.
One individual has often been claimed as the inventor of suminagashi. According to legend, Jizemon Hiroba felt he was divinely inspired to make suminagashi paper after he offered spiritual devotions at the Kasuga Shrine in Nara Prefecture. It is said that he then wandered the country looking for the best water with which to make his papers. He arrived in Echizen, Fukui Prefecture where he found the water especially conducive to making suminagashi. So he settled there, and his family carried on with the tradition to this day. The Hiroba Family claims to have made this form of marbled paper since 1151 CE for 55 generations (Narita 14).
History in Central Asia and the Islamic World 
In the 15th century the method of floating colors on the surface of mucilaginous sizing is thought to have emerged in Central Asia. It is believed to have appeared during the end of the Islamic Timurid Dynasty, whose final capital was in the city of Herat, located in Afghanistan today. Other sources suggest it emerged during the subsequent Shaybanid dynasty, in the cities of Samarqand or Bukhara, in what is now modern Uzbekistan. Whether or not this method was somehow related to earlier Chinese or Japanese methods mentioned above has never been concretely proven.
This Islamic method came to be known as kâghaz-e abrî (كاغذ ابرى), although often the simplified form of abrî (ابرى), is also found in several historic texts. This was translated by the late scholar Dr. Annemarie Schimmel to mean "clouded paper" in Persian. Certain Turkish writers have suggested that the word may be of Turkish origin related to the word abreh ابره meaning "colorful" or "variegated", though this specific term has never been concretely proven to have been used in relation to the art. It may have been the case that both Persian and Turkish meanings were simultaneously understood by artisans, many of which were conversant in both languages at that time, and even enjoyed as an expression of poetic nuance. Most historical Persian and Turkish texts known that refer to this kind of paper use the word abrî alone. Today in Iran it is often called abr-o-bâd (ابرو باد), meaning "cloud and wind".
The art developed in Safavid Persia and Ottoman Turkey, as well as Mughal and the Deccan Sultanates in India. Within these regions, various methods emerged in which colors were made to float on the surface of a bath of viscous liquid mucilage or size, made from various plants. These include katheera or kitre- gum tragacanth (Astragalus often used as a binder by apothecaries in making tablets), shambalîleh or methi- fenugreek seed (an ingredient in curry mixtures), and sahlab or salep (the roots of "Orchis mascula", which is commonly used to make a popular beverage). A method of manipulating colors evolved that employed various tools including rakes, combs, and other apparatus, utilized in a series of movements, resulted in incredibly elaborate, intricate, and mesmerizing designs. In India, the abri technique was eventually combined with 'aks, which are various methods of resist or stencils, to create unique and very rare form of miniature painting. These are commonly associated with the Deccan region today, and especially the city of Bijapur in particular, under Adil Shahi dynasty patronage in the 17th century. The topic of marbling in India is understudied and conclusive determinations have yet to be made, especially in light of discoveries made in the last 20 years.
In Turkey, the art is widely known as ebru today, and continues to be very popular. The usage of this term appears in the late 19th century. The earliest examples of Ottoman Ebru are thought to be a copy of the Hâlnâmah حالنامه by the poet Arifi, popularly known as the Guy-i Çevgan or "Ball and Polo-stick". The text of this manuscript was rendered in a delicate cut paper découpage calligraphy by Mehmed bin Gazanfer and completed in 1540, and features many marbled and decorative paper borders. One early master by the name of Shebek is mention posthumously in the earliest Ottoman text on the art known as the Tertib-i Risâle-i Ebrî (ترطیبِ رسالۀ ابری), which is dated based on internal evidence to after 1615. Several recipes in the text are accredited to this master. Another famous 18th century master by the name of Hatip Mehmed Effendi (d. 1773) is accredited with developing motif and perhaps early floral designs, although evidence from India appears to contradict some of these claims. Despite this, marbled motifs are commonly referred to as "Hatip" designs today in Turkey.
The current Turkish tradition of ebru dates to the mid 19th century, with a series of masters associated with a branch of the Naqshbandi Sufi order based at what is known as the Özbekler Tekkesi, located in Sultantepe, near Üsküdar. The founder of this line is accredited to Sadık Effendi (d. 1846). It is said that he learned the art in Bukhara and taught it to his sons Edhem and Salıh. Based upon this, many Turkish marblers have stated that the art was perpetuated by Sufis for centuries, although evidence for this claim has never been concretely established. "Hezarfen" Edhem Effendi (d. 1904) is attributed with developing the art as a kind of cottage industry for the tekke, to supply Istanbul's burgeoning printing industry with the decorative paper. It is said that the papers were tied into bundles and sold by weight. Many of these papers were of the neftli design, made with turpentine, an equivalent to what is called stormont in English.
The premier student of Edhem Effendi was Necmeddin Okyay (1885–1976). He was the first to teach the art at the Fine Arts Academy in Istanbul. He is famous for the development of floral styles of marbling, in addition to yazılı ebru a method of writing traditional calligraphy using a gum-resist method in conjunction with ebru. Okyay's premier student was Mustafa Düzgünman (1920–1990), the teacher of many contemporary marblers in Turkey today. He is known for codifying the traditional repertoire of patterns, to which he only added a floral daisy design, in the manner of his teacher.
History in Europe 
In the 17th century European travelers to the Middle East collected examples of these papers and bound them into alba amicorum, which literally means "books of friendship" in Latin, and is a forerunner of the modern autograph album. Eventually the technique for making the papers reached Europe, where they became a popular covering material not only for book covers and end-papers, but also for lining chests, drawers, and bookshelves. The marbling of the edges of books was also a European adaptation of the art.
The unique methods of marbling attracted the curiosity of early scientists during the Renaissance. While the earliest published account was written in German by Daniel Schwenter, it wasn't published in his Delicæ Physico-Mathematicæ until 1671 (Wolfe, 16). A brief description of the art by Athanasius Kircher, published in Ars Magna Lucis et Umbræ in Rome in 1646, rapidly spread throughout Europe. (ibid) A thorough overview of the art with illustrations of marblers at work, and images of the tools of the trade was published in the Encyclopédie of Denis Diderot and Jean le Rond d'Alembert.
The art became a popular handicraft in the 19th century after the English maker Charles Woolnough published his The Art of Marbling (1853). In it, he describes how he adapted a method of marbling onto book-cloth, which he exhibited at the Crystal Palace Exhibition in 1851. (Wolfe, 79) Further developments in the art were made by Josef Halfer, a bookbinder of German origin, who lived in Budakeszi, in Hungary. It was Halfer who discovered a method for preserving carrageenan, and his methods superseded earlier ones in Europe and the US.
Marbled paper is still made today, and the method is now applied to fabric and three-dimensional surfaces, as well as paper. Aside from continued traditional applications, artists now explore using the method as a kind of painting technique, and as an element in collage. In the last two decades, marbling has been the subject of international symposia and museum exhibitions. An active international group can be found on Yahoo! Groups, as well as the Society of Marbling, an organization of practicing marblers.
The first International Marblers' Gathering was held in Santa Fe NM in 1989 sponsored by the marbling journal Ink & Gall.
