Chalk
There is no statuary limit to the size of a chalkboard (better known as A blackboard in Britain schools, as it was a matt black board, and the chalk was white, sometimes coloured chalk was used).
The Luhya translation of the English words 'chalk board' is "lisisi lie ichoka".
A compound word with chalk is chalkboard.
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.

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.
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.
chalk has a compound in it that releases the glow when wet.
