Paper has been traced to China in about AD 105. It reached Central Asia by 751 and Baghdad by 793, and then by the 14th century there were paper mills in several parts of Europe. The invention of the printing press in about 1450 greatly increased the need for paper, and at the beginning of the 19th century wood and other vegetable pulps began to replace rags as the main source of fibre for papermaking.
Earlier than 1798, Nicholas-Louis Robert invented the earliest paper-making machine. With a moving screen belt, it was made one sheet at a time by the dipping of or mould with a screen bottom into a vat of pulp. Several years later the brothers Henry and Sealy Fourdrinier improved Robert’s machine, and then in 1809 John Dickinson invented the first cylinder machine.
Although almost all steps in papermaking are now highly mechanized, the basic process has remained mostly unchanged. First, the fibres are separated and wetted to create the paper pulp, or stock. The pulp is then filtered on a woven screen to form a sheet of fibre, which is then pressed and compacted to squeeze out most of the water. The remaining water is removed by evaporation, and the dry sheet is further compressed and, depending upon the intended use, coated or impregnated with other substances.
Differences regarding grades and types of paper are determined by several factors: the type of fibre used; the manner in which pulp is prepared, which is either by mechanical (groundwood) or chemical (primarily sulfite, soda, or sulfate) methods, or by a combination of the two; by the adding of more materials to the pulp, the most commonly used being bleach or colouring and sizing, the latter to impede penetration by ink; by conditions under which the sheet is formed, including its weight; and by the physical or chemical treatment applied to the finished sheet.
Although wood has become the major source of fibre for papermaking, rag fibres are still used for paper of the greatest strength, durability, and permanence. Recycled wastepaper (including newsprint) and cardboard are also important sources. Additional fibres used include straw, bagasse (residue from crushed sugarcane), esparto, bamboo, flax, hemp, jute, and kenaf. Some paper, in particular specialty items, is created from synthetic fibres.
Weight or substance per unit area, called basis weight, is measured in reams (now commonly 500 sheets). Paper is also measured by caliper (thickness) and density. The strength and durability of paper is determined by factors such as the strength and length of the fibres, as well as their bonding ability, and the formation and structure of the sheet. The visible properties of paper include its brightness, colour, opacity, and gloss. Among the most important paper grades are bond, book, bristol, groundwood and newsprint, kraft, paperboard, and sanitary.

Once you have obtained these important tools, you are ready to explore the world of art without any inhibitions or reservations. Here are the necessary supplies that can inspire you to create your very own masterpiece.
Paintbrushes
Every painter needs a brush to convey a message to his or her audience. Start collecting different types of brushes that can assist you while you are exploring different painting techniques. Start with a flat synthetic brush to create simple works of art. As your skills continue to improve, look for other art supplies such as flat bristle brushes, Filbert brushes, and sable brushes (and think outside of the box, trying items such as rubber wedges, potato/lino cut shapes}. All of these tools can add spice to every idea you were able to put into paintings.
Palettes and palette knives
While you are using oil-based paint, you will need to use a wood palette to hold them. Do not forget to clean your palette at the end of all your painting sessions. If you need to use acrylic paints, use a paper palette or any plastic surface instead of a wooden palette.
You can use palette knives to mix the paint on your wooden or paper palette. Try to find trowel-shaped palette knives that you can use to remove the paint from your canvas or palette.
Oil paint and special mediums
Oil paint is one of the most common art supplies used for painting pictures with beautiful textures. Their versatile nature can help you use thin and thick textures for your artworks. Since they tend to dry slowly, you will have plenty of time to work the oil paint on the canvas and to scrape some of the paint off for revisions.
You will also need special mediums to thin the oil paint whenever it becomes too thick. You can also use it for cleaning your brushes and using special techniques such as glazing.
Artist’s canvas
When buying canvases, you should have the option to purchase a stretched canvas or a canvas board. Stretched canvases are conveniently mounted on stretcher bars, that can be displayed on walls even when they are not framed.
If you have a limited budget, try using canvas boards as an alternative to high-end stretched canvases. Although they are cheaper than stretched canvases, they can deliver better results with their durable card panels and versatile surfaces.
With these four key art supplies, you are ready share the beautiful images you were able to visualise by preserving them into a wonderful work of art.

Abstract Art is a vast movement in American painting that began during the late forties and turned into a popular trend in Western painting throughout the fifties. The leading American Abstract Expressionist painters were Jackson Pollock, Willem de Kooning, Franz Kline, and Mark Rothko. Contemporaries were Clyfford Still, Philip Guston, Helen Frankenthaler, Barnett Newman, Adolph Gottlieb, Robert Motherwell, Lee Krasner, Bradley Walker Tomlin, William Baziotes, Ad Reinhardt, Richard Pousette-Dart, Elaine de Kooning, and Jack Tworkov. Several of these artists worked, lived, or had shows in New York City.
Despite the fact that it is the commonly accepted designation, Abstract Expressionism is not the most accurate description of the type of art created by those artists. Indeed, the movement had several different painterly styles varying in both skill and quality of application. Despite this, Abstract Expressionist paintings also share many common aspects. They are fundamentally abstract — meaning, they consist of forms which are not taken from the visible world.
They furthermore master limitless, spontaneous, and personal emotional expression, and they display vast freedom of technical skill and execution to achieve this result, with a particular emphasis put on the exploitation of the malleable physical characteristic of paint to evoke expressive qualities (such as, sensuousness, dynamism, violence, mystery, lyricism). They lay a similar importance on the unstudied and intuitive use of that paint in a kind of artistic improvisation like the automatism of the Surrealists, with the same purpose of expressing the power of the creative unconscious in art. They exhibit the conscious abandonment of regularly structured composition found from discrete and segregable effects and their replacement with a unique and unified, unvaried partition, network, or other image that exists in unstructured space. Finally, the paintings fill huge canvases to give such aforementioned visual elements both monumentality and engrossing strength.
The earlier Abstract Expressionists had two original forerunners: Arshile Gorky, who painted sensual biomorphic shapes using a free, lightly linear and liquid paint application; and Hans Hofmann, who created dynamic and harshly textured brushwork in his abstract but conventionally constructed works. Another important influence on nascent Abstract Expressionism was the arrival on Western shores in the late 1930s and early 40s of a group of Surrealists and other European avant-garde artists escaping the Nazi party in Europe. The European artists greatly impressed the native New York City painters and privileged for them a detailed understanding of the vanguard of European paintings. The Abstract Expressionist movement itself is generally regarded as having started with the painting done by Jackson Pollock and Willem de Kooning during the late forties and early 50s.
With regard to the variation of techniques of the Abstract Expressionist movement, three common approaches can be found. The first was action painting which is signified by a loose, quickfire, dynamic, or violent handling of paint in sweeping or slashing brushstrokes, and in application somewhat dictated by chance, i.e. dripping or spilling paint openly onto the canvas. Pollock first practiced action painting by dripping commercial paints on the raw canvas to build up layered and tangled skeins of paint into stimulating and suggestive linear patterns. De Kooning utilised very vigorous and expressive brushstrokes to build richly coloured and textured images. Kline used powerful, sweeping black strokes on white canvas for starkly monumental forms.
The second ground within Abstract Expressionism is represented by numerous varied styles going from the lightly lyrical, delicate imagery and fluid shapes seen in paintings by Guston and Frankenthaler to the clearly structured, forceful, almost calligraphic artworks of Motherwell and Gottlieb.
The third and least emotionally expressive area was that of Rothko, Newman, and Reinhardt. These painters had large areas or blocks of flat colour and weak diaphanous paint to master quiet, subtle, almost meditative results. The leading colour-field painter was Rothko; the large part of his works consist of large-scale combinations of soft-edged, solidly coloured rectangular fields that tend to shimmer and resonate.
Abstract Expressionism made a particular influence on both the American and European art trends through the 50s. Indeed, the movement initiated the shift of the creative centre of modern painting from Paris to New York City throughout the postwar years. Throughout the period of the 50s, the the movement’s young artists increasingly took to the trend of the colour-field painters. By the 1960s, the movement’s young artists had mostly drifted away from the high voltage expressiveness of the action painters.
