From English permanent means permanent. This suggests that permanent markers differ from ordinary markers in their ability to retain color for a long time, do not fade, do not wear off.
Marker in the traditional sense
Since the invention, the marker has undergone significant changes both in composition and in its characteristics. Markers are divided into non-permanent and permanent, that is, erasable and not.
The first to appear were non-pendent markers known as felt-tip pens. The writing and drawing accessory consists of a plastic case, a vented or non-vented cap, a porous fiber rod impregnated with dye, which ends with an oval or wedge-shaped tip. High-quality markers are environmentally friendly, they are based on water, and they retain their properties for a long time. Some markers are disposable, and some can be refilled after you use the paint.
The marker was invented in Japan in the middle of the last century. The first models were banned shortly after release due to the high lead content in the composition.
There are different kinds of simple markers:
- children's markers for drawing on paper;
- children's easy-to-erase markers;
- light markers for highlighting text (often with a wedge-shaped tip in blue, pink, yellow and green);
- markers for marking and recording on CDs and DVDs, films, glass (most often they have a thin rod and blue or black ink with a quick-drying base);
- rear projection markers used on overhead scopes, transparent foil, plastic and glass;
- markers for flipcharts and whiteboards that can be wiped off with a dry sponge or napkin.
Permanent marker properties
Permanent markers are known not only for the resistance of their inks to moisture, but also for their ability to retain color when exposed to high temperatures and ultraviolet radiation. On a smooth surface, the marker mark can be erased with alcohol or a plastic eraser.
With the help of permanent markers, you can decorate clothes, accessories, dishes. After applying the pattern to the ceramics, the product should be “baked” in the oven.
Some models are based on liquid ink instead of a dye-impregnated fiber rod. The service life of such markers increases significantly.
Permanent markers can be used on almost any surface made of paper, plastic, rubber, leather, metal, glass. The ink does not bleed and leaves a clean line.
