Erasers serve two primary purposes:
1. Removing Mistakes:
The most common use of an eraser is to remove unwanted marks made by pencils, pens, or other writing tools. This is particularly useful for correcting errors in writing, drawing, or sketching.
Erasers are designed to lift away the graphite or ink from the surface, leaving a clean and blank space for corrections.
Different types of erasers are suited for specific types of markings like lead pencils, colored pencils, or ballpoint pens.
2. Cleaning and Smudging:
Erasers can also be used for cleaning and smudging.
For example, artists use erasers to blend and soften lines in drawings, creating a more subtle and nuanced effect.
Erasers can also be used to remove excess graphite from surfaces, ensuring a clean and polished finish.
