How is Chalk Made?

It is a simple yet effective tool that has been used for centuries. But have you ever wondered how it is made? Here is a brief overview of the process:

a. It is made from calcium carbonate, a mineral that is found in the shells of marine animals.
b. The first step in making it is to crush the raw material, which is typically limestone, into a fine powder.
c. The powder is then mixed with water to form a paste. This paste is poured into moulds and left to dry.
d. Once it has dried, it is removed from the moulds and cut into pieces of the desired size.
e. The pieces are then coated with a thin layer of binding material, such as clay, which helps them to stick to surfaces like blackboards or chalk slates.
f. Finally, the pieces are packaged and sent to stores for sale.

Dustless is made using the same process but with the addition of a special oil that reduces dust production. Some brands of dustless, like Kores Dustless Chalk and Green Dustless, are quite popular in the market.

Overall, the process of making it is straightforward, and the resulting tool is an essential part of many industries, from education to construction to the arts.
