Pen
A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity which had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing. Types Modern Pens commonly used today can be categorized based on the mechanism of the writing tip and the type of ink: * A ballpoint pen di ...

Fountain Pen
A fountain pen is a writing instrument which uses a metal nib to apply a water-based ink to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits the ink on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism which creates suction (for example, through a piston mechanism) or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges. History Early prototypes of reservoir pens According to Qadi al-Nu'man al-Tamimi (d. 974) in his ''Kitab al-Majalis wa 'l-musayarat'', the Fatimid caliph Al-Mu'izz li-Din Allah in Arab Egypt demanded a pen that would not stain his ha ...

Ballpoint Pen
A ballpoint pen, also known as a biro (British English), ball pen (Hong Kong, Indian and Philippine English), or dot pen (Nepali) is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e. over a "ball point". The metal commonly used is steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre. Some pen manufacturers produce designer ballpoint pens for the high-end and collectors' markets. History Origins The concept of using a "ball point" within a writing instrument to apply ink to paper has existed since the late 19th century. In these inventions, the ink was placed in a thin tube whose end was blocked by a tiny ball, held so that it could not slip into the tube or fall out of ...

Dip Pen
A dip pen or nib pen or pen nib usually consists of a metal nib with capillary channels like those of fountain pen nibs, mounted in a handle or holder, often made of wood. Other materials can be used for the holder, including bone, metal and plastic; some pens are made entirely of glass. Generally, dip pens have no ink reservoir, so the user must recharge the ink from an ink bowl or bottle to continue drawing or writing. There are simple, tiny tubular reservoirs that illustrators sometimes clip onto dip pens, which allow drawing for several minutes without recharging the nib. Recharging can be done by dipping into an inkwell, but it is also possible to charge the pen with an eyedropper, a syringe, or a brush, which gives more control over the amount of ink applied. Thus, "dip pens" are not necessarily dipped; many illustrators call them "nib pens". Dip pens emerged in the early 19th century, when they replaced quill pens and, in some parts of the world, reed pens. Dip pens ...

Nib (pen)
A nib is the part of a quill, dip pen, fountain pen, ball point or stylus which comes into contact with the writing surface in order to deposit ink. Different types of nibs vary in their purpose, shape and size, as well as the material from which they are made. History Quill The quill replaced the reed pen across Europe by the Early Middle Ages and remained the main writing tool of the West for nearly a thousand years until the 17th century. Quills are fashioned by cutting a nib into the end of a feather obtained from a fairly large bird, such as a goose, traditionally from its left wing. A quill has the advantage of being more durable and more flexible than a reed pen, and it can also retain ink in the hollow shaft of the feather, known as the calamus, allowing more writing time between ink dippings. The quill was in common use until the early 19th century and the advent of the metal nib. For business purposes, the quill was fairly quickly overtaken; however, it remains popular ...

Writing Tool
A writing implement or writing instrument is an object used to produce writing. Writing consists of different figures, lines, and or forms. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the ordinary requirement to create a smooth, controllable line. Another writing implement employed by a smaller population is the stylus used in conjunction with the slate for punching out the dots in Braille. Autonomous An autonomous writing implement is one that cannot "run out"—the only way to render it useless is to destroy it. Without pigment The oldest known examples were created by incising a flat surface with a rigid tool rather than applying pigment with a secondary object, e.g., Chinese jiaguwen carved into turtle shells. However, this may simply represent the relative durability of such artifacts rather than truly representing the evolution of techniques, as the meaningful application ...

Viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. Experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube with a constant rate of flow, the strength of the compensating force is proportional to the fluid's viscosity. In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is ...

Quill
A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal- nibbed pen, the fountain pen, and, eventually, the ballpoint pen. As with the earlier reed pen (and later dip pen), a quill has no internal ink reservoir and therefore needs to periodically be dipped into an inkwell during writing. The hand-cut goose quill is rarely used as a calligraphy tool anymore because many papers are now derived from wood pulp and would quickly wear a quill down. However, it is still the tool of choice for a few scribes who have noted that quills provide an unmatched sharp stroke as well as greater flexibility than a steel pen. Description The shaft of a flight feather is long and hollow, making it an obvious candidate for being crafted into a pen. The process of making a quill from a feather involves curing the shaft to harden it, then fashioning its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porous Point Pen
A marker pen, fine liner, marking pen, felt-tip pen, felt pen, flow marker, sign pen (in South Korea), vivid (in New Zealand), texta (in Australia), sketch pen (in South Asia) or koki (in South Africa), is a pen which has its own ink source and a tip made of porous, pressed fibers such as felt. A marker pen consists of a container (glass, aluminum or plastic) and a core of an absorbent material that holds the ink. The upper part of the marker contains the nib that was made in earlier times of a hard felt material, and a cap to prevent the marker from drying out. Until the early 1990s, the most common solvents that were used for the ink in permanent markers were toluene and xylene. These two substances are both harmful and characterized by a very strong smell. Today, the ink is usually made on the basis of alcohols (e.g. 1-Propanol, 1-butanol, diacetone alcohol and cresols). Markers may be waterproof, dry-erase, wet-erase (e.g. transparency markers), or permanent. Hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rollerball Pen
Roller ball pens or roll pens are pens which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pens. These less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give roller ball pens their distinctive writing qualities. The writing point is a tiny ball, usually 0.5 or 0.7 mm in diameter, that transfers the ink from the reservoir onto the paper as the pen moves. Advantages There are two main types of roller ball pens: liquid ink pens and gel ink pens. The 'liquid-ink' type uses an ink and ink supply system similar to a fountain pen, and they are designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen. The 'liquid-ink' type rollerball pens were introduced in 1963 by the Japanese company Ohto. The gel ink type rollerball pens were patented in 1982 by Sakura Color Products. Gel inks usua ...

Rotring
Rotring (stylized rOtring) is a former German manufacturing company of technical drawing tools and writing implements. Established in 1928 as a fountain pen manufacturer, Rotring is currently a brand owned by Newell Brands after its acquisition in 1998. The name "Rotring" directly translates to "red ring" which is still placed around the barrel of their pens today. The company's name was changed to Rotring in the early 1970s to match the trademark. As the Rotring factory and headquarters in Hamburg were shut down, production has been handled and distributed by Japanese manufacturer Holbein and other manufacturers.

Technical Pen
A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. " Rapidograph" is a trademarked name for one type of technical pen. Technical pens use either a refillable ink reservoir (Isograph version) or a replaceable ink cartridge. History Early technical pens (ruling pens) consisted of a small pair of calipers, having one flat and one bowed leg holding ink between them. By adjusting the gap between the legs the width of the line drawn by the pen could be adjusted. Such pens, kept at a constant angle to the paper, were used for ruling lines, but not for cursive handwriting, nor for off-hand flourishes. The ''Graphos'' technical pen introduced in 1934 miniaturized the caliper principle and made the points easily interchangeable. The Sheaffer company produced an expensive drafting set which included such pens for use on linen prints. These sets were often presented ...
