Sharpies and Permanent Markers
Transcript of Sharpies and Permanent Markers
By Jane Loney
The History of the Sharpie
The Function of the Sharpie
Major Materials in the Permanent Marker
Why These Materials?
Origin of One of the Materials
The Sharpie (permanent marker) was invented by the Sanford Ink Company in 1964.
This Company had multiple locations around the United States of America.
Over time, the permanent marker has gained multiple new colors. When it was first invented, it had only black, but now the Sharpie has a total of 39 different colors.
The purpose of the Sharpie/permanent marker is to write on surfaces such as wood, paper, metal, and glass and write just like a pen.
The three main materials in a permanent marker are plastic, felt and ink.
The ink is so that the user can write in multiple colors, just like a pen.
The felt is used as the tip of the marker.
The plastic is used in a casing for the ink, and is connected to the felt tip.
The ink in permanent markers is made out of a colorant (a dye or pigment), a solvent (alcohol that dries the ink by evaporating once put on a surface), a resin (a polymer that is similar to glue), and linseed oil, which comes from flax seeds and is mixed with the colorant.

The purpose of the ink is for the user to be able to write in different colors, just like a pen.
The purpose of the felt is to have a tip for the marker that allows the ink to come out at a moderate pace.
The purpose of the plastic is to have a comfortable case for the marker that prevents the ink from coming out anywhere but the tip.

The ink is not flammable, not toxic, and it has very low acidity, which makes it safe. The ink also has a high boiling point (349 degrees Celsius), so it can withstand high temperatures. The ink can be many different colors depending on the dye used, and ink has low sensitivity to light which make it permanent.

The felt tips are not toxic or acidic, which makes them safe to use. Also, it is not sensitive to light, and it does not oxidize, which keeps the tip from drying out. The felt also allows the ink to be efficiently delivered to the surface.
The plastic casing does not oxidize, and it is strong, so it will not be easily damaged. Also, it is not sensitive to light so the marker will last for a long time. Also, the plastic is not toxic or acidic and it has a high melting point, making it safe for the user.
Dyes and pigments (the colorant) were first used by cavemen over 15,000 years ago to create drawings, but since it was so long ago, the first actual location of dyes being used is unknown.
Flax seeds (linseed oil) is cultivated in many parts of the world, and it has been cultivated for a long time, so the geographical origin of flax seeds is unknown
The solvent and resin in ink are not natural resources (they are chemicals), so they have no real geographic origin
