Why sprinkle white powder while smelting 🤔 #shorts

Have you ever wondered why blacksmiths always sprinkle white powder just before the metal is melted. This is done because borax white powder acts as a protective layer that reduces direct contact of the metal with air, preventing oxidation during the heat process. In addition, it is common for metal raw materials to be of low purity and have a lot of impurities. if the impurities are not removed, it will affect the quality of the metal. With the addition of borax, slag and impurities can be separated more effectively from the molten metal, thereby increasing the purity of the metal produced during the smelting process.
