What is canvas and its usage?


Date: 08/10/2011 02:36:52

Canvas is an extremely heavy-duty plain-woven fabric used for making sails, tents, marquees, backpacks, and other items for which sturdiness is required. It is also popularly used by artists as a painting surface, typically stretched across a wooden frame. It is also used in such fashion objects as handbags and shoes.


Physical characteristics

Modern canvas is usually made of cotton or linen, although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven. The term duck comes from the Dutch word for cloth, doek. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a graded number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than number 4.

Canvas for painting

Canvas has become the most common support medium for oil painting, replacing wooden panels. One of the earliest surviving oils on canvas is a French Madonna with angels from around 1410 in the Gem?ldegalerie, Berlin. However, panel painting remained more common until the 16th century in Italy and the 17th century in Northern Europe. Mantegna and Venetian artists were among those leading the change; Venetian sail canvas was readily available and regarded as the best quality.



Early canvas was made of linen, sturdy brownish fabric of considerable strength. Linen is particularly suitable for the use of oil paint. In the early 20th century, cotton canvas, often referred to as "cotton duck", came into use. Linen is composed of higher quality material, and remains popular with many professional artists, especially those who work with oil paint. Cotton duck, which stretches more fully and has an even, mechanical weave, offers a more economical alternative. The advent of acrylic paint has greatly increased the popularity and use of cotton duck canvas. Linen and cotton derive from two entirely different plants, the flax plant and the cotton plant.

Gesso-ed canvases on stretchers are also available. These pre-stretched, pre-primed canvases are suitable for all but the most exacting professional standards. They are available in a variety of weights: light-weight is about 4 oz (110 g). or 5 oz (140 g).; medium-weight is about 7 oz (200 g). or 8 oz (230 g).; heavy-weight is about 10 oz (280 g). or 12 oz (340 g). They are prepared with two or three coats of gesso and are ready for use straight away. Artists desiring greater control of their painting surface may add a coat or two of their preferred gesso. Professional artists who wish to work on canvas may prepare their own canvas in the traditional manner.

Canvas used for canoes

Wood-and-canvas canoes are made by fastening an external waterproofed canvas shell to a wooden hull formed with white cedar planks and ribs. These canoes evolved directly from birchbark construction. Maine was the location of the development of commercial wood-and-canvas canoes. E. H. Gerrish, of Bangor, is now recognized as the first person to produce wood-and-canvas canoes commercially, but other Maine builders soon followed, including, B. N. Morris, of Veazie, E. M. White, of Old Town, and, of course, the Gray family of the Old Town Canoe Co. In the adjoining Canadian province of New Brunswick, from the late 19th century until being disbanded in 1979, the Chestnut Canoe Company, along with the Old Town Canoe Company in Maine, became the pre-eminent producers of wood-and-canvas canoes. American President Teddy Roosevelt purchased Chestnut canoes for a South American expedition. Wood-and-canvas canoes have undergone a resurgence in recent years, spurred in part by the Wooden Canoe Heritage Association.[4] Builders abound, including Jerry Stelmok, Rollin Thurlow, Ken Solway, Joe Seliga, and many others.

Canvas used for trampolines

Canvas has become a very popular choice of use for trampoline manufacturers in the last decade. As the number of trampoline sales has increased in the UK, so has the amount of canvas used in order to make them. Cheaper trampolines often substitute a less durable woven fabric in place of canvas, making them more apt to damage when used simultaneously by more than one person. The more expensive canvas can endure multiple-person use.

Non-traditional uses for stretched canvas

It has become popular to use the myriad of stretched canvasses sizes and shapes for unconventional creative expression. Artists can create miniature works on business card sized stretched canvas and use them as trading cards to make connections with other artists. Many artists use canvas for altered art pieces as well as for scrapbook pages—because stretched canvas is available in many sizes, from miniatures to wall size, it is used for decoupage and needlework projects, made into lamps, or painted simply for home decor.
