Reed pens with regular features such as a split nib have been found in Ancient Egyptian sites dating from the 4th century BC. Reed pens were used for writing on papyrus , and were the most common writing implement in antiquity. In Mesopotamia and Sumer , reed pens were used by pressing the tips into clay tablets to create written records, using cuneiform. To make a reed pen, scribes would take an undamaged piece of reed about 20 cm, and leave the end that would be cut into point in water for some time.

This ensured that the pen would not splinter when cut. They crafted a series of cuts that would cut the nib of the pen until it was flat enough, and pointed. The pointed end was then cut off, not too far from the point, to form a squared end suitable for writing. At the end they would start the split, which would act as a primitive ink barrel, from the tip of the nib and lengthen it until it was of the proper length.

Can an examination be conducted of a signature or handwriting from only a photocopy? Yes, but if it is possible to obtain the original it allows a more thorough examination of the document and the circumstances of its production. The possibility of a tracing of a machine copy transfer forgery cannot be ruled out.

Blackwing Pencils: A Comprehensive Guide

A stylus plural styli is a writing implement used to scratch letters into the wax of a writing tablet. A pencil makes a coloured mark on wood, paper or parchment. A writing tablet was usually made from wood or bone and had slightly recessed panels filled with wax see, for example, the early-medieval Blythburgh tablet , and a medieval example from London, Egan no. Wax may have been superseded as a writing medium in about the 13th century Clanchy , It is thought that Roman wax tablets were filled with clean wax using a spatula, often with a handle in the form of a bust of Minerva e.

Many pointed objects could potentially be used to scratch letters into wax, and defining exactly what is or was a stylus can sometimes be problematic.

History of Pencils and Pens

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.

Some of the possibilities, meth ods, and results of submitting written materials to examina tion by test tube and micro scope. Seven or eight years ago an intelligence officer came into possession, under circumstances which aroused his professional ardor, of a small scrap of notepaper bearing only an address and a very common first name scribbled underneath it. For two years he persisted in trying to identify the writer of this note, collecting handwriting specimens from a number of likely places and submitting them for laboratory comparison.

Some of them matched the original. The points of venue of these marked the writer’s trail through several trouble-ridden countries, but none identified him. Finally, back in his own country, the traveler wrote to one of the prospectively useful acquaintances he had made on the trip, and this correspondent was careless enough to let the letter fall into our intelligence officer’s hands.

Verified as the same handwriting, it gave a complete name and home address. A search of visa records and other materials on file now yielded the true identity of the writer, his cover story, background, and even photographs of him. He is a Soviet intelligence officer, who since then, thanks to this identification, has unwittingly kept us informed by his presence of certain activities of his organization.

For twelve years, beginning during World War II, an agent in Europe had provided generous and significant reports from around and behind the iron curtain. He had apparently built up a network of informants extending deep into the denied areas. But now a sharp-eyed postal intelligence officer noticed an incorrect postal cachet on one of his envelopes, and his whole file of odd reports was therefore brought to the questioned document laboratory. Analysis showed that the reports were written by eight different typewriters, which might correspond to eight different informants; but some reports from widely separated places had been produced on the same day by the same machine, and the principal agent’s own correspondence turned out to have been written on one or another of the typewriters supposedly used by his secret informants behind the curtain.

It was not a crude paper mill, but careless enough to get caught, finally.

Pencils and pens are ancient writing tools which were first used some years ago but are still used today despite the electronic technology that we use for communication. Here you can read more about history of pencils and other writing instruments, including biography of prominent inventors, interesting facts and making process of various writing tools.

Since we learned to talk, we tried to write what was said. We started with images then simplified them until we came to words and letters. We wrote these letters with crude tools which in time became more and more perfect. Same was with ballpoint and fountain pen. Throughout the history, we made different pens and pencils to serve us as we need them to. Ballpoint pens and pencils look like simple writing instruments: they have pigment in their core and housing that protects the core from outer elements and outer elements from being stained by the core.

But they are not that simple – otherwise, we would have got pencils and ballpoint pens much earlier than we did. Many drawing tools are used for drawing, draughting and design.

But this technique is also able to overcome other stumbling blocks relating to the amount of ink deposited when writing and the type of paper used, as these variables hamper the dating of a document by means of traditional methods. What is more, the new technique reduces the number of punctures needed to analyse the writing on a document to just one. Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.

Until now, document dating methods have been able to indicate whether the writing was relatively new less than 90 days or older over two years , yet this chronological accuracy is insufficient in certain cases, above all in judicial ones. Each document was produced at different moments using a different ink stroke pressure, factors that may alter the results and lead to dating errors. During the natural ageing process of each sample, which had a known age, the research team analysed the evolution in the various volatile components.

When analysing the kinetics involved in its disappearance, the research group established a pattern that links the state of the ink with the time that has elapsed. After observing this natural evolution and once the base guideline had been established, the next challenge to be overcome was to check the viability of the method using spontaneously written documents whose exact age was known, such as diaries, laboratory logs and judicial evidence from judicial processes that had been closed.

So the team used the same procedure as that used to analyse the samples produced for the research. And Datink also passed the test. In other words, when applying this analysis procedure, the team can indicate whether the document was written 1, days previously just over four years with a margin of days either way. Until now, the passing of time was detected only in a very general way, in other words, it was possible to determine whether the document was young whether it was less than 90 days old or old more than 2 years.

So Datink has overcome some of the drawbacks graphology examination comes up against when ascertaining the age of a document by means of other methods.
