What is an eraser made of?

Answer 1

A variety of specialized erasers are manufactured today. The type of eraser often attached to pencils is usually pink or red, and has a smooth, rubbery texture. It is good for most erasing purposes, though it tends to smear and can damage the paper if used too heavily. It leaves eraser residue that must be brushed away; care must be taken in brushing away residue, as the eraser particles can leave marks on the paper.

Another eraser type that is popular with artists is the art gum eraser, made of soft, coarse rubber. It is especially suited to removing large areas, and does not damage the paper. This eraser leaves a lot of eraser residue, however, and is not very precise. Art gum erasers are commonly tan or brown.

The kneaded eraser (or kneaded rubber eraser) is also well-known among artists. It is usually made of a grey or white pliable material that resembles putty or gum. It functions by "absorbing" and "picking up" graphite and charcoal particles. It does not wear away and leave behind eraser residue, thus it lasts much longer than other erasers. Kneaded erasers can be shaped with the fingers and used for precision erasing, to create highlights, or for detailing work. It is commonly used to remove light charcoal and light graphite marks in subtractive drawing techniques. However, it is not well-suited to completely erasing large areas, and may smear or stick if it becomes too warm. Though it does not wear away like other erasers but it can become exhausted, unable to absorb any more graphite or charcoal in which case it will start to smear and actually make marks instead of erasing them.

Soft vinyl erasers have a plastic-like texture, and are similar in erasing characteristics to the standard pink erasers; they are somewhat softer, though, and are therefore less likely to damage the canvas or paper. Vinyl erasers are commonly white.

Erasers come in several shapes and sizes. In addition to those that come attached to pencils, they may also be rectangular blocks (block or wedge eraser), or conical caps that can slip onto the end of a pencil (cap eraser). A barrel or click eraser is a device shaped like a pencil, but instead of being filled with pencil lead, its barrel contains a retractable cylinder of eraser material. Novelty erasers are made in a wide variety of shapes, colors, and designs to suit their themes (such as musical notes, animals, confectionery), and they are typically acquired more for their decorative nature than for any practical use.
