What's erasers?

Who invented it?

By King of EarthPublished about a year ago 4 min read

I. Introduction

An eraser is a tool used to remove pencil and pen marks from paper and other surfaces. The earliest known eraser was created in 1770 by Edward Nairne, a British artist and stationer, who made erasers out of rubber. Since then, the technology of erasers has evolved to include various materials and forms.

II. Types of erasers

There are several different types of erasers available, each with their own specific uses and advantages:

Rubber erasers: These are the most common type of eraser, made from a mixture of rubber and other materials. They are effective at removing pencil marks and can also be used to lighten pen marks.

Pencil erasers: These erasers are designed specifically for erasing pencil marks and are typically smaller in size than rubber erasers. They are often made from a softer material and have a more precise erasing tip.

Kneaded erasers: These erasers are made from a soft, pliable material that can be kneaded and shaped to fit into tight spaces or erase small details. They are often used by artists for erasing pencil marks in drawings.

Electric erasers: These erasers use a battery-powered motor to rotate a small eraser tip, making them effective for quickly erasing large areas. They are often used in drafting and technical drawing.

Liquid erasers: These erasers come in a liquid form and can be applied with a brush or pen tip. They work by dissolving the graphite in pencil marks.

Other specialized erasers: There are also specialized erasers available such as whiteboard erasers and art erasers. Whiteboard erasers are designed for use on whiteboard surfaces, while art erasers are intended for use with charcoal and pastels.

III. Uses of erasers

Erasers have a variety of uses, including:

Erasing pencil and pen marks: The most common use of erasers is to remove pencil and pen marks from paper and other surfaces.

Cleaning up drawings and artwork: Artists often use erasers to lighten or remove pencil marks in their drawings and artwork.

Removing mistakes in typing and printing: Erasers are also used to correct mistakes made in typing and printing.

Cleaning surfaces: Erasers can also be used to clean surfaces such as whiteboards and chalkboards.

IV. How erasers work

Erasers work by physically or chemically removing the graphite or ink from the surface they are being used on. Rubber erasers work by gently abrading the surface and lifting the graphite or ink particles away. Liquid erasers dissolve the graphite particles using chemicals.

The materials used in erasers can vary, but most erasers are made from rubber, or a mixture of rubber and other materials. Some erasers also contain abrasive particles such as pumice or silicone.

V. Eraser care and maintenance

To ensure that erasers last as long as possible and work effectively, it is important to take good care of them. This includes:

Storing erasers in a cool, dry place to prevent them from drying out or becoming sticky.

Cleaning erasers regularly to remove debris and dirt.

Prolonging the life of erasers by not using them on rough surfaces or using excessive force when erasing.

VI. Environmental impact of erasers

Like many other everyday items, erasers have an impact on the environment. The materials used in erasers can be harmful to the environment if not disposed of properly. Additionally, eraser waste can contribute to land and water pollution

An eraser, also known as a rubber or a pencil eraser, is a small block of material used to remove pencil marks from paper. The most common type of eraser is made of rubber, but other materials such as vinyl, plastic, and gum-like substances are also used.

Erasers come in different sizes and shapes, including rectangular blocks, triangular shapes, and even novelty shapes such as animals or characters. Some erasers are designed specifically for use with mechanical pencils, while others are intended for use with traditional wooden pencils.

There are different types of erasers available in the market. The most common erasers are the pink erasers, which are made from natural rubber and are great for erasing graphite pencil marks. The white erasers are made from a synthetic rubber, and it is less abrasive and less likely to damage paper. The kneaded erasers are made from a pliable material that can be molded into different shapes, which makes them great for erasing in small or hard-to-reach areas.

Erasers can be used in a variety of settings, including classrooms, offices, and art studios. They are a common tool for students, artists, and writers, as they allow for easy correction of mistakes. Some erasers are also used for erasing mistakes made on chalkboards or whiteboards.

To use an eraser, simply rub it gently over the area of the paper that you wish to remove the pencil marks from. It is important to use a light touch when erasing, as pressing too hard can cause the eraser to remove more than just the pencil marks, or damage the paper.

In summary, eraser is a small block of material used to remove pencil marks from paper. It comes in different sizes and shapes, and different types of erasers are available in the market. Erasers are a common tool for students, artists, and writers, as they allow for easy correction of mistakes. It is important to use a light touch when erasing, as pressing too hard can cause the eraser to remove more than just the pencil marks, or damage the paper.
