What is the procedure n making chalk using cassava?
To make chalk using cassava, first, the cassava roots are peeled, washed, and then grated or ground into a pulp. The pulp is then mixed with water and allowed to settle, separating the starch from the fibrous material.

Finally, the mixture is shaped into sticks or powder and allowed to dry completely before use.
