The earliest form of stationery used to remove pencil markings is known as the eraser. It was discovered in 1770 that natural rubber made from plants can be used as an eraser. The stationery is made in different shapes, sizes, and colours from various materials. However, the low-grade ones are usually made with synthetic soy-based gum or synthetic rubber. On the other hand, the higher quality erasers are made from materials such as vinyl, plastic and much more.
Erasers have become more high-tech in the recent years, as it does not only come in different shapes and sizes. The latest kinds of erasers are known as the “art gum erasers” which are made of soft, coarse rubber and are ideal for erasing larger areas so that the paper is not easily damaged. Nonetheless, the downside to these types of erasers is that it crumbles when it is being utilized and the residue has to be removed. For graphite or charcoal lead, the kneaded eraser or putty rubber will be suitable to be used as it absorbs it from the surface. It also does not leave behind any residue and lasts longer compared to the art gum erasers.
The correction fluid was invented in 1951 by Bette Nesmith Graham, where an opaque, white fluid is applied to a part any text that contains errors. This was during the introduction of electric typewriters where the carbon-film ribbons made it impossible to have mistakes corrected neatly with just a pencil eraser. Due to the trouble that Graham and her colleagues were experiencing with the electric typewriters, she decided to find an easier alternative. Her inspiration for the correction fluid came from her observation of painters, where they would cover any imperfections simply by painting over it. From that, Graham utilized a white, water-based tempera paint to cover her typing errors. Over the years, she continued experimenting with the makeup of the material until she attained the ideal combination. It was not until 1958, the refined product was named “Liquid Paper” which continues to be a popular correction pen until today.
Perhaps one of the best ways to correct errors is with a correction tape where users are able to achieve a more professional look without any drying time. It is often used as an alternative to the correction pens. The white coated side of the tape will be placed against the error. Pressure is then applied so that it transfers the material on to the paper. The correction tape was invented by a Japanese brand Seed and was introduced in 1989. There are many forms of correction tape, but the most popular kinds are sold in short spools for the purpose of hand use, where it glides onto the paper smoothly. Moreover, the user has more control over the correction tape giving any document a clean, professional look.
