(Redirected from Writing implements)
Styli used in writing in the Fourteenth Century.
A writing implement or writing instrument is an object used to produce writing. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the unique requirement to create a smooth, controllable line.
Another widely-used writing implement is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille.
Autonomous writing instruments
These have an inherent functionality in that their useful life corresponds to their length of their physical existence, i.e. they cannot “run out” and persist as useless objects.
Without pigment
The oldest known examples of writing 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 of pigment is attested in prehistoric cave paintings such as the ones at Lascaux.
The ancient Sumerians and their successor cultures, such as the Babylonians, produced their cuneiform writing by pressing a triangular stylus into soft clay tablets, creating characteristic wedge-shaped marks. The clay tablets were then baked to harden them and permanently preserve the marks.
Several other ancient cultures such as Mycenaean Greece also inscribed their records into clay tablets but did not routinely bake them; much of the Linear B corpus from Minoan Crete was accidentally preserved by a catastrophic fire which hard-baked those tablets. The Romans used lead styli with wax tablets which could be “erased” by rubbing the beeswax surface smooth again.
In the modern era, hand held computers and certain other computer input devices use a stylus to enter information onto a screen by applying pressure rather than by depositing pigment.
Words and names are still commonly inscribed into commemorative objects, such as the engraved winners’ names on the silver Stanley Cup or the Gettysburg Address carved into the stone wall of the Lincoln Memorial, but the requisite tools are not exclusively considered to be writing instruments.
With inherent pigment
The original form of “lead pencil” was the lead stylus used by the ancient Romans, who also used it to write on wood or papyrus by leaving dark streaks where the soft metal rubbed off onto the surface. However, most modern “lead pencils” have a nonpoisonous core of greyish-black graphite mixed with various proportions of clay for consistency, enclosed within an outer wooden casing to protect the fragile graphite from being snapped apart or from leaving marks on the user’s hand.
White chalk has been traditionally used in schoolrooms to write on a main blackboard at the front of the room. In the 19th century, and indeed well into the 20th century, when paper was less readily available, individual students also wrote with chalk on their own small slates.
Both pencils and chalk exist in variants which can create marks in other colors, but colored pencils and colored chalk are generally considered to be art supplies rather than writing instruments. Similarly, although very young children may use colorful wax crayons to write words into their pictures, writing is not considered to be the primary use of crayons.
A wax pencil resembles both a crayon and a pencil in that it contains a brightly colored wax core within a protective paper casing, but its proportions are closer to that of a standard pencil. Wax pencils are primarily used to write onto nonporous surfaces such as porcelain or glass.
Normal pencils, chalk, and crayons all share the characteristic that they cannot “run out”. The useful life of these implements is closely linked to their physical existence. However, specialized accessories such as pencil sharpeners may be required to reshape the working end of the pigment core or to remove the outer casing from around the tip.
Assisted writing implements
These require the presence of an added pigment in order to write, and are useless when “empty”.
Pens
The pen is the most common form of writing implement. It has a hard tip which applies ink to a surface.
Capillary-action dip pens
Initially, pens were made by slicing a suitable nib point from the end of a thin, hollow natural…(and so on) To get More information , you can visit some products about discount wall tiles, home ceramic tile, . The Shampoo Shape Radio with Speaker And Antenna products should be show more here!
