The Art of Tooth Powder Making
(Original Title: 法造製粉牙)
In the wake of China’s economic challenges, there is a pressing need to foster the growth of domestic industries. This editorial outlines a straightforward method to produce tooth powder using local ingredients: six parts of quicklime, six parts of borax, and twelve parts of charcoal. The starting point involves finely grinding the ingredients and mixing them with a small amount of water to achieve a smooth paste. Once prepared, this economical solution not only saves costs but also encourages supporting national industries and reducing dependency on foreign goods.
