BLACKBOARD DUSTER Meaning and
Definition
-
A blackboard duster, also referred to as an eraser or chalkboard eraser, is an essential tool used for cleaning and erasing markings made with chalk on a blackboard or chalkboard. It is specifically designed to facilitate effortless removal of chalk dust and residue, ensuring a clean and clear writing surface for future use.
Typically, a blackboard duster consists of a rectangular or square-shaped felt pad encased in a wooden frame or plastic shell. The felt pad is compatible with chalk and possesses a gentle abrasive quality that effectively lifts the chalk particles from the blackboard without damaging the surface. It is specifically engineered to pick up the chalk dust when glided over the writing area.
When erasing, the user holds the blackboard duster firmly and sweeps it horizontally or vertically across the blackboard, depending on personal preference or the desired cleaning pattern. The felt pad swiftly absorbs the chalk particles into its fibers due to the static electricity generated by the friction between the pad and board.
Blackboard dusters are commonly used in educational institutions such as schools and universities, as well as in commercial settings like meeting rooms or lecture halls. They play a crucial role in maintaining a tidy blackboard, allowing for a fresh start with each new lesson or presentation.

Etymology of BLACKBOARD DUSTER
The term "blackboard duster" can be broken down into two parts: "blackboard" and "duster".
The word "blackboard" originated in the early 19th century and refers to a smooth, dark-colored surface made of slate, wood, or other materials, on which writings or drawings can be made using chalk. The term "blackboard" is derived from the surface's characteristic color, as it was commonly dark or black.
The word "duster" has a more general origin. It comes from the verb "dust", which refers to the action of removing or wiping away dust or particles from a surface. "Duster" specifically signifies an object or tool used for dusting.
