First, let's understand how the ceramic mug transforms from clay to cup: 1. Practice the mud: Take the porcelain stone from the mining area, finely pour the water, wash it, remove the impurities, and precipitate into a brick-like mud. Then mix the mud with water, remove the slag, rub it with your hands, or step on it with your feet, squeeze ...
