Product Introduction: The main raw material of chalk is gypsum, which is also an important ingredient in making tofu. Our chalk does not contain any additional chemicals during the production process. Of course, it is not edible, as it is non-toxic. Regarding the dust-free feature, it is a result of the combined action of friction and the molecular attraction during writing with chalk, which produces the powder.
