A canvas is an especially sturdy woven cloth used for creating sails, tents, marquees, backpacks, and different things that strength is needed, still as in such fashion objects as handbags, electronic device cases, and shoes. It is additionally popularly utilized by artists as a painting surface, generally stretched across a picket frame.
Modern canvas is typically fabricated from cotton or linen, along with polyvinyl chloride, although historically it was made from hemp.

· For painting
Canvas has become the foremost common support medium for oil painting, replacing wooden panels. It was used from the ordinal century in European nation, but only rarely. One of the earliest extant oils on canvas could be a French Madonna with angels from around 1410 within the Gemäldegalerie, Berlin. Its use in patron saint and therefore the Dragon by Paolo Uccello in concerning 1470, and Sandro Botticelli's Birth of Venus within the 1480s was still uncommon for the amount. Large paintings for country houses were apparently more likely to be on canvas, and are perhaps less likely to have survived. It was an honest deal cheaper than a panel painting, and may sometime indicate a painting regarded as less important. In the Uccello, the armour does not use silver leaf, as other of his paintings do (and the colour therefore remains undegraded). Another common category of paintings on lighter cloth such as linen was in distemper or glue, often used for banners to be carried in procession. This is a less sturdy medium, and extant examples like sticker Bouts' sepulture, in distemper on linen (1450s, National Gallery) are rare, and often rather faded in appearance.
Panel painting remained additional common till the sixteenth century in European nation and therefore the seventeenth century in geographic region. Mantegna and Venetian artists were among those leading the change; Venetian sail canvas was pronto on the market and thought to be the simplest quality.
Canvas is usually stretched across a picket frame known as a stretcher and should be coated with gesso before it's to be used; this can be to stop paint from coming into direct contact with the canvas fibres, which can eventually cause the canvas to decay. A traditional and versatile chalk gesso consists of pigment and oil, applied over a rabbit skin glue ground; a variation using titanium white pigment and calcium carbonate is rather brittle and susceptible to cracking. As lead-based paint is toxic, care has to be taken in using it. Various various and additional versatile canvas primers are commercially on the market, the foremost fashionable being an artificial rubber-based paint composed of pigment and carbonate, sure with a thermo-plastic emulsion. Many artists have painted onto unprimed canvas, such as Jackson Pollock, Kenneth Noland, Francis Bacon, Helen Frankenthaler, Dan Christensen, Larry Zox, Ronnie Landfield, Color Field painters, Lyrical Abstractionists and others. Staining paint into the material of cotton duck canvas was additional benign and fewer damaging to the material of the canvas than the utilization of paint. In 1970 creative person Helen Frankenthaler commented concerning her use of staining:
Canvas could be a fashionable base cloth for embroidery like cross-stitch and Berlin wool work. Some specific types of embroidery canvases are Aida cloth (also called Java canvas), Penelope canvas, Chess canvas, and Binca canvas. Plastic canvas is a stiffer form of Binca canvas.
