For my science fair project, I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice, vinegar, water, and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic, paper, fabric, and wood. In this research paper, I will be talking about what a permanent marker is, how they are made, why they work so well, what rubbing alcohol is and its common uses, what vinegar is and its common uses, what water is and why water is so essential, and what exactly lemon juice is. I will also be talking about how plastic is made, how fabric is made, how wood is made, and how paper is made. A permanent marker is a type of writing utensil that is used to create permanent lines on almost any surface. The ink of a permanent marker is water resistant, contains propanol, butanol, diacetone alcohol, and different dye colorings, and can vary between all colors from black to yellow. The process of creating a Sharpie permanent marker is not very long or complicated. First, the barrel of the marker is molded out of a plastic resin. Screen printing is added to the barrel, including information such as the description of the color of the ink and the Sharpie logo. A filament made out of cotton material is used to hold in the ink as it is inserted into the barrel. A needle is used to inject the permanent ink from the opposite end of the barrel. Then the writing tip is applied. The cap is placed on the Sharpie marker and the permanent ink is slowly absorbed into the tip of the marker. The Sharpie is the most popular permanent marker company worldwide. The brand “Sharpie” was founded in 1857 and sold ink and glue. Any permanent marker’s ink must contain three ingredients to work. These ingredients are colorant, carrier, and resin. The colorant is what gives the ink its color. Colorants in permanent markers are often pigments, instead of dyes, because pigments fade less easily and do not bleed through paper. Dyes are...
