Calcium carbonate chalk is a type of chalk that is made from calcium carbonate, a mineral compound found in rocks and shells. This type of chalk is commonly used in classrooms, offices, and other settings where writing or drawing on a chalkboard is required. Good quality dustless calcium carbonate chalk is preferred as it reduces the amount of dust produced while writing or erasing on a chalkboard, making it easier to clean and healthier for those who may be sensitive to dust.
When purchasing calcium carbonate chalk, it is important to look for a reputable brand that offers good quality dustless chalk. It is also important to consider the size and shape of the chalk, as well as any additional features such as a non-slip grip or a dust-free formula.
