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.
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.
* 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.
Some of the chalk is dissolved into the water and so when you write on a board the chalk can not easily be seen. The water then evaporates leaving only chalk behind therefore becoming visible.
Chalk need to be sprayed with a fixative, or the loose chalk particles will rub off from any surface. I believe there is an acrylic fixative spray available. Or you could gently spray thinned down acrylic medium onto the chalk if the board is laid flat. Experiment on a bit of scrap so you don't spoil the main art work.
Chalk consists of calcium carbonate, which is insoluble in water. Therefore, chalk does not dissolve in water but rather forms a suspension or slurry when mixed with water. The rate at which the chalk particles settle out of the water depends on factors such as particle size and water movement.

When you crush chalk, the solid structure of the chalk breaks down into smaller particles. This results in a powder-like substance that is easier to spread and work with.

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.
SANDie Well it will be like sand, or it could be a powder. If it is a blue kind of chalk, when you crush the blue chalk, it will be blue. Sometimes, it could be a nice smooth powder. Sometimes, it could be into pieces instead. You have to crush it more to make it like sand or powder. But sand has rocks and hard ones. So this might be powder.
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.
