In addition to the field of education, chalk also plays an important role in conferences, speeches, and other occasions. In the conference room, chalk became a tool for attendees to record key points and discuss issues; On the podium, chalk helps the speaker draw charts and outline ideas, making the speech more vivid and powerful. The simplicity, clarity, and intuitiveness of chalk make it an effective way of communication in these situations.

Chalk has become a powerful assistant in the field of education due to its unique material and texture. It is made of limestone and after fine processing, it presents a smooth and hard surface. This material allows chalk to maintain stable friction and clarity during writing, with smooth and less blurry handwriting. At the same time, the writing effect of chalk also has a certain degree of durability, and can remain relatively clear even in damp or friction environments.

Non toxic chalk is made by solidifying and drying pure gypsum with water, using edible gypsum. Most teaching abroad has been using this type of chalk since elementary school. Non toxic chalk belongs to advanced chalk, and it is non-toxic in the dust pollution of classroom chalk. The dust generated by it can be directly excreted by the human body through excretion without remaining in the body. Even the water in production causes zero pollution to the river.

Regular chalk is prone to moisture absorption, decreased hardness, and easy breakage when stored for a long time. The blackboards used in schools include cement boards, wooden boards, and ground glass boards. Due to different levels of smoothness on the surface of the blackboards, the softness and hardness of the chalk are also required. The new generation of dust-free chalk can change its softness and hardness at will, and will not slip or break easily when used on various blackboards. It also writes fluently, effortlessly, and has a good hand feel. Dust free chalk is a high-tech product that has been successfully developed in addition to cosmetic materials used in production. Environmentally friendly, non-toxic, dust-free, it is an ideal teaching and office supplies for modern teaching.

Dust free chalk adds trace amounts of chemical raw materials to the main ingredients, increasing the proportion. The chalk is written on the blackboard, without dust flying phenomenon, and is hygienic and clean, avoiding occupational diseases caused by chalk foam entering the internal organs through breathing. Add a small amount of smoothing agent and adhesive, the chalk should not touch hands and clothes, and the teacher should have no white marks on their fingers after a class, so there is no need to wash hands. Add a small amount of moisture-proof agent, which will not spoil when stored for a long time.
