The manufacturing process starts with quarrying limestone. It is present on the land or inside it in the form of deposits. Big machinery like bulldozers and scrapers are used to extract it. This limestone is then fed into pulverizes, where it is first crushed into small pieces then ground. Then, it has to go through a process like sifting and cleaning to obtain fine and clean chalk powder. In the next step, the manufacturers add water, clay and other pigments to make the final chalk sticks.
