With every stroke of the chalk piece it leaves some of the chalk on the board. This abrasion of the piece of chalk causes it to wear down.
This is similar to why the rubber tyres of cars wear down when they are driven over a road surface.

Hair chalk can be made by mixing non-toxic soft pastels with a bit of water to create a paste-like consistency. You can then apply the hair chalk onto small sections of hair and allow it to dry before setting it with heat. Remember to wear gloves and protect your clothes to prevent staining.

Marble is a harder and more durable material compared to chalk, making it better suited for flooring in terms of longevity and resistance to wear and tear. Marble also offers a luxurious and elegant aesthetic that is preferred for high-end applications like flooring in homes, hotels, and other commercial buildings. Additionally, marble can be polished to a high shine and comes in a wide range of colors and patterns, providing more design options compared to chalk.
Cobalt is a very strong glass, so it is used to make cooking wear or baking wear,and also used for simple things like glasses and mugs or cups. Sometimes they use coblat for windows, but that is rare since it can be hard to make a big piece of it.
Blackboards are typically made of a material that is softer than chalk, such as slate or porcelain. When you write on a blackboard with chalk, the friction between the chalk and the board causes the chalk to wear down and leave behind tiny particles of sand or abrasive material embedded in the chalk. These abrasive particles then scratch the surface of the blackboard as you write, creating marks that can be difficult to erase.
I started my life as a blank slate, eager to be filled with knowledge and creativity. Over time, I became covered in markings and erased repeatedly, bearing the weight of countless lessons and ideas. Despite the wear and tear, I stand as a testament to the power of education and the impact of every stroke of chalk.
