törleszköz

Törleszköz is a Hungarian term that translates to "erasing device" or "eraser" in English. It refers to any object used to remove marks made by writing instruments, typically pencils or chalk. The most common form of törleszköz is a rectangular block made of rubber, vinyl, or other pliable materials, designed to be rubbed against paper to lift graphite or other pigment from its surface. These erasers come in various shapes, sizes, and degrees of hardness, each suited for different types of marks and papers.

Beyond the standard block eraser, the term törleszköz can also encompass more specialized erasing tools. For instance, a kneaded eraser, often made of a pliable, putty-like rubber compound, is used by artists and draftsmen. It works by absorbing graphite rather than abrading the paper, allowing for subtle corrections and lightening of tones without damage to the drawing surface. Mechanical erasers, which contain a refillable stick of erasing material within a pen-like casing, also fall under the umbrella of törleszköz. These offer precision for small details.

The principle behind most törleszköz is friction. As the eraser is rubbed against the writing medium, the friction generates heat and causes the eraser material to bond with and lift the pigment particles from the paper. The quality of the törleszköz can significantly impact the effectiveness of the erasure and the condition of the paper afterward, with some lower-quality erasers potentially smudging the mark or damaging the paper's surface.
