Blackboard chalk is composed of calcium carbonate.

the colour of chalk(calcium carbonate) in its natural state is white.
the natural state of 'chalk' is green when they make it It's true , because I'm a person who studies chalk
Chalk is a natural material composed primarily of calcium carbonate, which is formed from the remains of marine organisms over millions of years. It occurs in sedimentary rock layers and is often found in chalk cliffs. While synthetic chalk exists, such as that used for chalkboards or sports, traditional chalk is derived from natural geological processes.
Chalk is a form of limestone, or calcium carbonate (CaCO3). Refer to the related links for more information about chalk.
Chalk (calcium carbonate, CaCO3) is found in nature, being a natural product.
Chalk is a natural mineral formed from the remains of marine organisms such as plankton and algae. It is composed mostly of calcium carbonate.
lumber and water
There is natural chalk. The sticks that the teacher uses to write on slate blackboards is powdered natural chalk compressed into sticks with some binder; so they are man made.
Chalk is harder than rubber. Chalk is a form of limestone made of calcium carbonate, which is a relatively hard mineral, whereas rubber is a soft and flexible material typically made from natural or synthetic polymers.
Chalk used in toothpaste is typically collected from natural deposits or synthetically produced. Natural chalk deposits are mined from underground and then processed to remove impurities. Synthetic chalk is manufactured by combining calcium carbonate and other ingredients. Once collected, the chalk is finely ground and purified to be used in toothpaste formulations.
