Stump (drawing)
A stump is a cylindrical drawing tool, usually made of soft paper that is tightly wound into a stick and sanded to a point at both ends. It is used by artists to smudge or blend marks made with charcoal, Conté crayon, pencil or other drawing media. By its use, gradations and half tones can be produced. Stumps are typically made of paper but can also be made of felt or leather. They are sold commercially in a range of sizes suitable for manipulations covering large areas, for operations on a miniature scale, and those in-between. A variant that is not as tightly packed and has a hollow core is called tortillon A tortillon (; also blending stump) is a cylindrical drawing tool, tapered at the end and usually made of rolled paper, used by artists to smudge or blend marks made with charcoal, Conté crayon, pencil or other drawing utensils.

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal. This process happens naturally when combustion is incomplete, and is sometimes used in radiocarbon dating. It also happens inadvertently while burning wood, as in a fireplace or wood stove. The visible flame in these is due to combustion of the volatile gases exuded as the wood turns into charcoal. The soot and smoke commonly given off by wood fires result from incomplete combustion of those volatiles. Charcoal burns at a higher temper ...

Conté Crayon
Conté (), also known as Conté sticks or Conté crayons, are a drawing medium composed of compressed powdered graphite or charcoal mixed with a clay base, square in cross-section. They were invented in 1795 by Nicolas-Jacques Conté, who created the combination of clay and graphite in response to the shortage of graphite caused by the Napoleonic Wars (when the British naval blockade of France prevented import). Conté crayons had the advantage of being cost-effective to produce, and easy to manufacture in controlled grades of hardness. They are now manufactured using natural pigments (iron oxides, carbon black, titanium dioxide), clay (kaolin), and a binder (cellulose ether). Conté crayons are most commonly found in black, white, and sanguine tones, as well as bistre, shades of grey, and other colors. Colors sets are especially useful for field studies and color studies. Some artists create entire paintings with them, using them more like pastels than like a drawing medium. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pencil
A pencil () is a writing or drawing implement with a solid pigment core in a protective casing that reduces the risk of core breakage, and keeps it from marking the user's hand. Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface. Most pencil cores are made of graphite powder mixed with a clay binder. Graphite pencils (traditionally known as "lead pencils") produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging. Other types of pencil cores, such as those of charcoal, are mainly used for drawing and sketching. Coloured pencils are sometimes used by teachers or editors to correct submitted texts, but are typically regarded as art supplies, especially those with cores made from wax-based binders that tend to smear when ...

Felt
Felt is a textile material that is produced by matting, condensing and pressing fibers together. Felt can be made of natural fibers such as wool or animal fur, or from synthetic fibers such as petroleum-based acrylic or acrylonitrile or wood pulp–based rayon. Blended fibers are also common. Natural fibre felt has special properties that allow it to be used for a wide variety of purposes. "It is fire-retardant and self-extinguishing; it dampens vibration and absorbs sound; and it can hold large amounts of fluid without feeling wet..." History Felt from wool is one of the oldest known textiles. Many cultures have legends as to the origins of felt making. Sumerian legend claims that the secret of feltmaking was discovered by Urnamman of Lagash. The story of Saint Clement and Saint Christopher relates that the men packed their sandals with wool to prevent blisters while fleeing from persecution. At the end of their journey, the movement and sweat had turned the wool into f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortillon
A tortillon (; also blending stump) is a cylindrical drawing tool, tapered at the end and usually made of rolled paper, used by artists to smudge or blend marks made with charcoal, Conté crayon, pencil or other drawing utensils. A blending stump is similar to a tortillon but is longer, more tightly wrapped, and pointed at both ends. Tortillons produce slightly different textures than stumps when blending, and they also are hollow, as opposed to stumps being solid. Cleaning of tortillons and stumps usually involves removing the used outer layer of paper by scraping or rubbing the implement on an abrasive surface, such as sandpaper, carpet A carpet is a textile floor covering typically consisting of an upper layer of pile attached to a backing.
