The History of Paper

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 a number of places in 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 foremost source of fibre for papermaking.

Earlier than 1798, Nicholas-Louis Robert invented the first paper-making machine. Using a moving screen belt, it was made one sheet at a time by dipping a frame or mould which has a screen bottom into a vat of pulp. Several years later the brothers Henry and Sealy Fourdrinier improved Robert’s machine, and in 1809 John Dickinson invented the first cylinder machine.

Although most steps in papermaking are now highly mechanized, the basic process has remained mostly unchanged. Firstly, the fibres are separated and wetted to produce the paper pulp, or stock. The pulp is then filtered on a woven screen that forms 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 among the grades and types of paper are determined by a number of factors: the type of fibre used; the preparation of the pulp, which can be either by mechanical (groundwood) or chemical (primarily sulfite, soda, or sulfate) methods, or by a combination of the two; by the addition of more substances to the pulp, the most common 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 treatments applied to the resulting sheet.

Although wood has become the foremost source of fibre for papermaking, rag fibres are still used for paper of maximum strength, resistance to mould, and permanence. Recycled wastepaper (including newsprint) and paperboard are also important sources. Additional fibres used include straw, bagasse (residue from crushed sugarcane), esparto, bamboo, flax, hemp, jute, and kenaf. Some paper, particularly specialty items, is made 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.

Four Essential Art Supplies for Professional and Budding Painters

Before you can create the best artworks that reflect your unique painting style, you will need to secure four essential art supplies that can help you express your deepest feelings onto the canvas. Once you have obtained these important tools, you can already explore the world of art without anything holding you back. Here are the most important supplies that can inspire you to create your very own masterpiece.

Paintbrushes
Every painter needs a brush to convey a sensation to his or her audience. Start finding 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 a mix 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 look for 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 images 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 enough 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 when it becomes too thick. You can also use it for cleaning your brushes and using special techniques such as glazing.

Artist’s canvas
When shopping for canvases, you usually have the option to purchase a stretched canvas or a canvas board. Stretched canvases are conveniently mounted on stretcher bars, and 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 performance with their durable card panels and versatile surfaces.

With these four key art supplies, you can share the beautiful images you were able to visualise by preserving them into an exceptional work of art.

What is Abstract Art?

Abstract Art is a broad movement in American painting that began in the late 40s and was a predominant trend in Western painting throughout the 1950s. 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 the artists worked, lived, or exhibited their work in New York City.

Although it is the commonly accepted designation, Abstract Expressionism is not the proper category of the body of art created by these artists. In truth, the movement was made up of various different painterly styles that were different in both technical application and quality of application. Despite this variety, Abstract Expressionist paintings also share a number of wider traits. They are fundamentally abstract — i.e., they are based around forms which are not taken from the real world.

They furthermore proffer free, spontaneous, and unique emotional expression, and they display wide freedom of skill and execution to attain this goal, with a special emphasis targeted on the exploitation of the variable physical form of paint to call up expressive qualities (such as, sensuousness, dynamism, violence, mystery, lyricism). They exhibit a similar emphasis on the unstudied and intuitive application of the paint in a method of psychic improvisation in the trend of the automatism of the Surrealists, with the likewise intention of displaying the strength of the creative subconcious in art. They display the rejection of normally structured composition found out of discrete and segregable elements and their replacement with a unique and unified, unvaried field, network, or other image that exists in unstructured space. Lastly, the paintings fill big canvases to allow those aforementioned visual effects both monumentality and engrossing power.

The leading Abstract Expressionists had two notable forerunners: Arshile Gorky, who painted sensual biomorphic figures by using a free, intricately linear and liquid paint method; and Hans Hofmann, who had dynamic and fully textured brushwork in his abstract but conventionally structured artworks. Another special influence on nascent Abstract Expressionism was the arrival on the American shores in the late 30s and early 1940s of a host of Surrealists and other such European avant-garde artists arriving from the Nazi party in Europe. These artists greatly moved the native New York City painters and permitted them a detailed insight of the vanguard of European artwork. The Abstract Expressionist movement itself is generally seen as having started with the paintings done by Jackson Pollock and Willem de Kooning throughout the late 1940s and early fifties.

Keeping in mind the variety of styles of the Abstract Expressionist movement, three wide approaches can be distinguished. First was action painting which is characterized by a loose, quickfire, dynamic, or violent handling of paint in sweeping or slashing brushstrokes, and in techniques partially dictated by chance, for example dripping or spilling paint directly onto the canvas. Pollock initially practiced action painting by dripping commercial paints onto a raw canvas to build up complex and tangled skeins of paint into exciting and suggestive linear patterns. De Kooning had highly vigorous and expressive brushstrokes to build richly coloured and textured images. Kline employed powerful, sweeping black strokes onto the white canvas creating starkly monumental forms.

The next area of Abstract Expressionism is displayed by several varied styles from the highly lyrical, delicate imagery and fluid shapes in paintings by Guston and Frankenthaler to the more clearly structured, forceful, almost calligraphic paintings of Motherwell and Gottlieb.

The third and least emotionally expressive area was that of Rothko, Newman, and Reinhardt. These painters had large spaces or blocks of flat colour and weak diaphanous paint to create quiet, subtle, almost meditative results. The leading colour-field painter was Rothko; many of his works consist of wide combinations of soft-edged, solidly coloured rectangular blocks that tend to glimmer and resonate.

Abstract Expressionism had a wide influence on both the American and European art worlds throughout the fifties. Indeed, the movement sparked the change of the creative centre of modern painting from Paris to New York City throughout the postwar period. Throughout the course of the 50s, the the movement’s youth increasingly took the trend of the colour-field painters. By the 1960s, the movement’s young participants had mostly drifted away from the extreme expressiveness of the action painters.
