Chalk is able to write on a board because of its soft texture. When dragged across a rough surface like a chalkboard, the chalk leaves behind particles that stick to the surface, creating readable markings.
Blackboards are not scratched by chalk because chalk is softer than the material from which the blackboard is constructed. Sand scratches blackboards because it is harder than the material from which a blackboard is made.
Crushing a chalk board is not recommended as it can create a mess and cause damage to the surroundings. If necessary, it is best to dispose of an old chalkboard properly by recycling or seeking professional assistance for dismantling.
* The particles of dustless chalk are very heavy and tend to fall directly to the floor instead of floating in the air, while the particles of the normal chalk floats in the air. * The dustless chalk writes smoothly without scratch, while the normal chalk leaves some scratches on the board. * The dustless chalk does not break easily while the normal chalk breaks easily.
An article of chalk typically refers to a specific item or product made from chalk, such as chalk sticks used for writing on blackboards, chalk for marking, or art chalk for drawing. Chalk is primarily composed of calcium carbonate and is known for its soft, powdery texture. It has various applications in education, art, and industry. Additionally, the term "article of chalk" can also imply any manufactured good that is made using chalk as a primary material.

No, natural chalk found in nature is formed from the shells of marine organisms, while chalk used on chalkboards is typically made from gypsum or calcium sulfate. The chalkboard chalk is designed to have a smooth texture and be easily erased from chalkboards.
Chalk is made of calcium carbonate, a soft mineral that leaves a visible mark when drawn on a rough surface like a blackboard. When drawn on the blackboard, chalk particles rub off and stick to the surface due to friction, creating a visible line.

You can use it in homemade toothpaste recipes in place of baking soda. Also used in the construction trade when 'snapping' a chalk line on a board, etc.
It would be an insulator- chalk board erasers normally consist of two parts, a wooden handle and a soft pad that wipes off the chalk from the board. Neither of these parts are conductors of electricity.
