Can anyone tell me how to make grip powder at home with calcium carbonate and magnesium carbonate and any other ingredient if required. The issue is that I have no idea what should be the ratio of the ingredients. I recently checked out the difference between Victor and Yonex grip powder. While Victor has only a combination of calcium carbonate and magnesium carbonate powder, Yonex includes a whole lot of ingredients like Pine resin, magnesium carbonate, eggshell, calcium carbonate, zeolite. I need to know a simple yet effective grip powder that I can make at home.
