Ceramic glaze has no taste, even if it has taste, it may be the taste of organic coating on ceramic surface. Stainless steel generally has no taste, but stainless steel tableware cannot be washed with alkaline solution, because stainless steel contains trace harmful metals, which are easily absorbed by human body after being dissolved by alkali, which is harmful to health; Some printed porcelain tableware contains lead, which will accelerate volatilization after heating, causing harm to human body. Therefore, different tableware and kitchenware should cooperate with each other to achieve health benefits. Generally speaking, ceramic tableware is healthier. Because the toxicity of ceramic tableware is the weakest, and the toxicity of stainless steel tableware is weak. Different tableware and kitchenware produce different substances when cooking. These substances have an impact on people's health. If a substance exceeds a certain level, it will do harm to the body.
