In Depth Tutorials and Information Ink Analysis Introduction Chemical and physical analysis of inks on questioned documents provides valuable information regarding their authenticity. Comparison of these chemical and physical properties of two or more inks can determine: When dating tags are detected, it is possible to determine the actual year or years when the ink was manufactured. Dating tags are unique chemicals that have been added to ball-point inks by some ink companies as a way to determine the year the ink was made. Relative age comparison tests performed on inks of the same formula and written on the same type of paper with the same storage conditions performed by measuring changing solubility properties of inks can estimate how long inks have been written on paper. This is done by: In cases where known dated writings are not available for comparison with questioned inks, accelerated aging heating the ink to induce aging of the ink can sometimes be used to estimate the age of ink using any or all of the above described techniques. Iron-based inks can be dated by measuring the migration of iron along the fibers of the paper by Scanning auger microscopy. This article describes state of the art procedures for the chemical and physical comparison, identification and dating of inks on questioned documents. Composition of Major Types of Writing Inks Knowledge of the composition of inks is necessary to understand the reasons for the various methods used to analyze inks.
Spirograph pens: Felt-tip pens
Metal nibs have their origins as far back as ancient Egypt and were made of metals like copper and bronze. However, the quality of writing that could be achieved with these pens was inferior to that of reed pens. Metallic nibs were made up through the 18th-century as one-off, craftsman-made luxury items. Metal nibs are also easily manufactured to have different properties for different purposes.
A nib is the part of a quill, dip pen, fountain pen, 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.
Fountain pens by Chris Woodford. Will there come a time when handwriting is completely obsolete? It just might happen! Most of us write far less than we used to: If you’re lucky, you might still get letters and greetings cards in the mail that have been written out by hand. And if you’re super lucky, they might have been lovingly handwritten with a fountain pen—probably the most individual and expressive instrument you can use for sending a written message to another person.
How exactly do these ink-scribbling machines work? Let’s take a closer look! A quiver of fountain pens from my collection. These are all modern pens, but the design hasn’t changed much since the original pen of this type was invented in the late 19th century. The ones on either side are made by Parker; the pen in the middle is made by the Germany firm Pelikan. What is a fountain pen?
Writing technology is still much the same as it was several thousand years ago: Some things have moved on:

USk Symposium Meet the Correspondent: I don’t feel comfortable when I leave home without a sketchbook and some pens in my bag. I think that my way to put things in my memory is to draw them. And taking pictures isn’t the same thing. I live in a very dynamic surrounding — Israel is a warm country with warm weather and warm people. Of course, we have seashores, which calm us a little bit. I love to sit in a corner of some Tel-Aviv coffee shop and explore relationships: All this unique local mix of cultures, languages and styles is always a great source for inspiration.
You need to be fast, because, as I said, everything is very dynamic. But that’s why I love it so much. Sometimes, I look around, and I find some usual items like sugar bags or napkins. I use them in my drawings to show the atmosphere. Sometimes I draw directly on placemats.
Fountain Pen Guide Series, Session 1: Nibs, Feeds, and How They Come Together
It not only requires experience but also rare technical competence in areas as diverse as mechanical design engineering, prototyping, and testing. The pen uses dry ink tablets that are activated by adding water. In this year, Russell Parker also joins the company. Soon afterwards, Duofold becomes world famous with the ‘Big Red’ for its new bright orange colour and year guarantee.
If you’ve always wanted to see what it’s like to literally get the ink flowing with a fountain pen, this guide offers the basics you need to get started.
History[ edit ] Early prototypes of reservoir pens[ edit ] An early historical mention of what appears to be a reservoir pen dates back to the 10th century. According to Al-Qadi al-Nu’man d. Leonardo’s journals contain drawings with cross-sections of what appears to be a reservoir pen that works by both gravity and capillary action. Historians also took note of the fact that the handwriting in the inventor’s surviving journals is of a consistent contrast throughout, rather than the characteristic fading pattern typical of a quill pen caused by expending and re-dipping.
While no physical item survives, several working models were reconstructed in by artist Amerigo Bombara that have since been put on display in museums dedicated to Leonardo. Klein and Henry W. Wynne received US patent in for an ink chamber and delivery system in the handle of the fountain pen European reservoir models[ edit ] Deliciae physico-mathematicae, The fountain pen was available in Europe in the 17th century, and is shown by contemporary references.
In Deliciae Physico-Mathematicae a magazine , German inventor Daniel Schwenter described a pen made from two quills. One quill served as a reservoir for ink inside the other quill. The ink was sealed inside the quill with cork.

Abstract Additive manufacturing AM is poised to bring about a revolution in the way products are designed, manufactured, and distributed to end users. This technology has gained significant academic as well as industry interest due to its ability to create complex geometries with customizable material properties. AM has also inspired the development of the maker movement by democratizing design and manufacturing.
Due to the rapid proliferation of a wide variety of technologies associated with AM, there is a lack of a comprehensive set of design principles, manufacturing guidelines, and standardization of best practices. In order to advance research interest and investment in AM technologies, some fundamental questions and trends about the dependencies existing in these avenues need highlighting. The goal of our review paper is to organize this body of knowledge surrounding AM, and present current barriers, findings, and future trends significantly to the researchers.
We also discuss fundamental attributes of AM processes, evolution of the AM industry, and the affordances enabled by the emergence of AM in a variety of areas such as geometry processing, material design, and education. Previous article in issue.
By Rick Propas [Note: A list of sources and additional reading is to be found at the end of this piece. Rather this is meant to be a readable introduction to Pelikans for beginning collectors and newcomers] The history of Pelikan begins with Germany’s industrial revolution in the early nineteenth century and continues into the global economy of today. During that period, the firm has consistently been a technological leader, even as its fortunes rose and fell.
The purpose of the PENguin is to offer first rate, fully restored fountain pens, fountain pen information and useful resources.
And there are a few things one can do to heighten this pleasure, and its feeling of ritual. Another is improving your handwriting. The nature of the tool requires more skill and attention on your part, but the experience is richer and the result sharper. Fountain pens work by managing the rate at which the ink flows through the pen. When the pen is held at an upright angle, ink from the reservoir is drawn downward by gravity, and goes through the feed and to the nib in a controlled fashion.
Unless air is brought into the reservoir to replace the ink as it is used, a vacuum will build up that stops the flow. This created a capillary-esque mechanism that functioned by drawing ink into these small channels at the same time that air came back in over the fissures and entered the reservoir. The modern fountain pen was born. You had to unscrew a portion of the barrel and use an eyedropper to fill the reservoir drop by drop. At the turn of the 20th century, companies began introducing self-filling reservoirs that allowed users to put the nib in the inkbottle and fill the reservoir by pulling a lever or twisting the barrel.
Despite the introduction of the ballpoint pen in the early s, fountain pens maintained their dominance as the go-to writing instrument up until the mid-point of the century. Today you can find countless forums and blogs dedicated to the virtues of this classic writing instrument. Here are a few reasons to give fountain pens a try:
I have run across a few, but they have been in distressed external condition. Recently, this pen crossed my path and I made a nice trade for it. Moore Pens began near in Boston, Massachusetts and were a significant player in the fountain pen world for a good part of the first fifty years of the 20th Century.
India ink (British English: Indian Ink; also Chinese ink) is a simple black or colored ink once widely used for writing and printing and now more commonly used for drawing and outlining, especially when inking comic books and comic ink is also used in medical applications.
I also prefer very, very fine nibs, and they tend to present this sort of feel more than broader nibs. But why do certain nibs perform differently to others? Why is it that even two supposedly identical nibs can write differently to each other? What matters is how the nib is made, not what it is made from. There are normally one of a few main materials in the body of a nib: Gold is used because it is very flexible when compared to steel.
Steel nibs do exist with a flexible property, but they are notoriously difficult to make and often have to be done by professionals for a fee. The karat count is a very misleading detail. Higher karat nibs are often no better than lower karat nibs, and the reason 14k gold is so common is because it is easier to work with and is stronger and less prone to bending than 18k and 21k nibs. Many pen professionals such as Richard Binder vouch for 14k gold as the best nib material available.
The Pelikan M left has a steel nib, compared to the 14K gold nib on the M right The other metals on this list are uncommon, but more and more manufacturers are bringing out titanium nibs. Titanium is desirable because it has a matte texture to it, which can look good on certain pens. What happens is the nib is pressed out of a sheet of metal, bent into shape, and then a very hard metal is applied to the end.
The blob of metal is then polished and shaped into the desired size such as fine, medium, or broad.
Writing in your Bible is something that many people do but few do it judiciously. Many people only mark their Bible according to what they hear from the weekly sermon and after a while they underline or highlight everything making the actual process of marking your Bible pointless. There are many people that do not make any additional marks in their Bible and some even consider it heresy.
“Holy crap that family is awesome.” Needless to say, take on this family, or threaten one of its members, at your own peril—and don’t be surprised when you lose badly to them. The Godzilla “dynasty” is an unofficial example. The start was the original Godzilla now reborn as Kiryu being the.
It is a tribute to his resilience and persistence in the face of economic and business pressures. These were due to attempting to start and sustain a small size fountain pen company in the Midwest during a time of intense competition from bigger companies and the never ending needs of additional capital and legal battles from the likes of the Conklin Pen Company. That was a pen dating to approximately , a few years before this pen.
As you can read in that post, after Welty won his lawsuit against Conklin, he was in need of additional funding and brought in Evans as a partner in the Evans Pen Company. This is an example of a pen made in the short time that Welty and Moore were together, before Moore took over the line completely. It was the final move for Welty and the Company seems to have remained there into the s. At the end of this post I will show a picture of a Welty Chicago fountain Pen.
Here is a photo of the dismantled Servo Fountain Pen, which was probably produced sometime after in conjunction with Moore. The unique Welty Filler Patent can be found by clicking here. As you can see, the lever is reverse to most lever fillers and opens from front to back. It is a hooked shape lever that attaches to a pressure bar which is under the sac not above as in most lever fillers.
