What does a pen contain?
Common components include a ball, a point, ink, an ink reservoir or cartridge, and an outer housing. Some pens are topped with a cap to prevent it from leaking or having its point damaged. Other pens use a retractable point system for the same reason.
What is the science behind a pen?
The concept of the pen is very simple: gravity forces the ink down into a resevior, sitting atop the thing that puts the ink on the surface, which is aptly called a ball. As the pen presses against the surface, ink flows onto the ball, which move and basically pulls the ink onto the surface.
What is ink pen made of?
Ink Components The average ballpoint pen’s ink is composed of dye or pigment particles – carbon black for black pens, eosin for red, or a suspected cocktail of Prussian blue, crystal violet and phthalocyanine blue for the classic blue pen – suspended in a solvent of oil or water.
How do pens work?
Rather than a nib, a ballpoint pen has a small ball bearing for the ink. This ball bearing is typically made from brass, steel, or tungsten carbine. As the ball moves across paper, it turns and draws ink from the cartridge, creating a consistent ink line with a quick dry time.

How is a pen made?
They are made by extrusion or by injection molding. After cooling mold is opened and plastic piece retain its shape. When all pieces are formed, ballpoint pen is assembled. First, a tungsten ball is attached to the reservoir which is then injected with ink of the desired color.
Does pen ink contain metal?
Inks that employ pigments include white ink (which contains titanium oxide) and metallic gold ink (which, surprisingly, uses a copper-zinc alloy.) Carbon black, a pigment derived from coal and oil, is an essential part of black ballpoint pen ink.
How does the inside of a pen work?
This bearing ball is a miniscule metal sphere, usually made of either brass, steel, or tungsten carbide. As the writer moves the tip of the pen across a paper, the bearing ball rotates in its socket, transferring ink from the inside of the ink reservoir to the paper.
What is the function of pen?
pen is a common writing instrument used to apply ink to a surface, usually paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in ink.
What makes a pen different from other pens?
The anatomy of a pen is different for all the main types: stick pens, twist pens, ballpoint pens, and fountain pens. What do these writing instruments have in common? Easy – it’s all about the ink at the tip of a pen!
Can a stylus pen be used on a touch screen?
