History of Marker Pens In 1944, Walter J. De Groft patented a marking pen that held ink in liquid form in its handle and used a felt tip. This is the patent that will become a “Sharpie” pen in 1964. First popular (and usable) marker pen was Sidney Rosenthal's “Magic Marker” which he invented and started selling in 1953. This marker had glass tube of ink for a body and a felt wick and its name comes from a fact that it was able to write on any surface.

- More than 2 billion pens are manufactured in the United States annually. There are five main kinds of pens. They are (1) ballpoint pens, (2) fountain pens, (3) soft-tip pens, (4) rolling-ball pens, and (5) specialty pens. Ballpoint pens have a tiny ball made of brass, steel, or tungsten carbide as their writing tip. A compartment called the ink reservoir holds the ink, and a narrow tube links the reservoir to the ball.

Sharpie Pen Color Science â SICK Science How Does It Work. This is really a lesson in the concepts of solubility, color mixing, and the movement of molecules. The Sharpie markers contain permanent ink, which will not wash away with water. Permanent ink is hydrophobic, meaning it is not soluble in water. However, the molecules of ink are soluble in another solvent called rubbing alcohol. This solvent carries the different colors of ink with it as it spreads in a circular pattern from the center of the shirt.

Fountain pen ink Because fountain pens operate on the principle of capillary action, ink for them is almost exclusively dye-based. Pigment-based inks (which contain solid pigment particles in a liquid suspension) tend to clog the narrow passages of the pens. Some pigmented inks do exist for fountain pens, but these are uncommon. India ink, a carbon pigment-based ink, also contains a binder (such as shellac), which can quickly clog such pens. The ideal fountain pen ink is free-flowing, free of sediment, and non-corrosive.

How Do You Recycle Ink Pens? Probably, because that’s what we all do. It’s about the only thing you can do with an old pen. Complete pens can’t go into normal plastic recycling bins because they contain bits of metal, as well as the remainder of the ink.

Ballpoint Pen Precious metals such as gold, silver, or platinum are plated onto more expensive pens. The ink can be specially made by the pen manufacturer. To be useful in a ballpoint pen, the ink must be slightly thick, slow drying in the reservoir, and free of particles. These characteristics ensure that the ink continues to flow to the paper without clogging the ball.

Marker pen A marker pen, fineliner, marking pen, felt-tip marker, felt-tip pen, flow, marker or texta (in Australia) or sketch pen (in India), is a pen which has its own ink-source, and a tip made of porous, pressed fibers such as felt. A permanent marker consists of a container (glass, aluminum or plastic) and a core of an absorbent material.

Who Invented the marker Pen?... History. The felt-tip pen was invented by Sidney Rosenthal in 1953. This inventor from Richmond Hill, New York, placed a felt tip on the end of a small, stout bottle of permanent ink and discovered that the resulting marks saturated a heavy, absorbent surface, yielding rich color and permanence.

Marker Raw Materials. The marker body, cap, and plugs are formed from plastic resin. The marker reservoir, which holds the ink, is formed from polyester. Powder and water are used to form the felt writing tip. In addition, markers require ink, and the pigments and synthetic substances used to make it.

Pen A gel pen uses ink in which pigment is suspended in a water-based gel.[1] Because the ink is thick and opaque, it shows up more clearly on dark or slick surfaces than the typical inks used in ballpoint or felt tip pens. Gel pens can be used for many types of writing and illustration.

How Ballpoint Pens are made? Ballpoint pens are made of metals, plastic, and some other chemicals. When they were first made, for a ball it the point was used steel. Today is used textured tungsten carbide because it is resistant to deforming. The point that hold the ball is made of brass - alloy of copper and zinc.

ocean-ocean convergent boundary ( subduction and volcanic islands) When a convergent boundary occurs between two oceanic plates one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle and at a depth of about 100 miles (150 km) the plate begins to melt.

Fountain pen The feed of a fountain pen is the component that connects the nib of the pen with its ink reservoir. It not only allows the ink to flow to the nib (in what is often described as a controlled leak) but also regulates the amount of air flowing backwards up to the reservoir to replace this lost ink.

How Are Ballpoint Pens Made? A variety of components are used to make ballpoint pens, including plastic, metal and chemicals. In most ballpoint pens, the writing sphere is made from brass, although you can also use steel or tungsten. In metal pens, the body, ink cartridge and spring are also made of brass or aluminum. Virtually all ballpoint pens contain a significant amount of plastic. Even the most expensive pens use plastic for the push button, ink cartridge, cap and tip.

Can you get ink poisoning when someone stabs you with a pen? He is also a co-author of 'In Memory: A Tribute to Sir Terry Pratchett'. The only way that its possible to get ink poisoning from ANY type of pen is to swallow it, or if it gets inside of an open cut. Scientists who researched this proved that you …need to swallow an ounce or more of ink to get ink poisoning. However gel pens use water-based ink, so they are less of a risk and non-toxic.

- Ballpoint pen inks use dye because the tiny particles of undissolved pigment can clog the ball of the pen. The solvent of most inks is water or oil. Ballpoint pen ink is usually oil-based to give it its thickness. Oil also is why ballpoint pen ink dries quickly and is permanent and water-fast. Ink Components. Ballpoint pen ink is about 50 percent dye. Black ink gets its color from carbon black, a fine powder made from soot. Red ink is made from eosin. Several dyes are used to make blue ink, but the more common ones include substituted triphenylmethane dyes, copper phthalocyanine blue and crystal violet.

Pen 1 A fountain pen uses water-based liquid ink delivered through a nib. 2  The ink flows from a reservoir through a feed to the nib, then through the nib, due to capillary action and gravity. 3  The nib has no moving parts and delivers ink through a thin slit to the writing surface.
