When choosing porcelain tableware, you should lightly tap the porcelain with your index finger. If you can make a crisp sound, it indicates that the porcelain embryo is delicate and well-fired. If the rattle sound is dumb, it means that the porcelain is damaged or porcelain. The embryo quality is poor.

Enamel tableware

Enamel products have good mechanical strength, are strong, are not easily broken, and have good heat resistance, and can withstand a wide range of temperature changes. The texture is smooth, compact and not easy to be contaminated with dust, clean and durable. The disadvantage is that after being hit by an external force, there are often cracks and breaks.

Iron tableware

In addition, it is not advisable to use iron containers to hold edible oil, because the oil is easily oxidized and deteriorated when stored in iron for too long. At the same time, it is best not to use iron containers to cook foods and beverages rich in tannins, such as juice, brown sugar products, tea, coffee, etc.
