The relationship between ceramic cup and enamel cup

Ceramic cup we are often contacted, enamel cup now most people do not need, but enamel bowl and enamel tableware such as enamel basin, there are a lot of use. Both ceramic cups and enamel cups have porcelain, so what is the relationship between them?

An enamel cup is an appliance in which the metal is coated with one or more layers of enamel on the inside and outside. The enamel on the outside of the enamel cup is composed of sodium silicate and metal salts. General pure white enamel products do not contain lead, but contain heavy metals such as aluminum, and other color have to add some metal salts, so the enamel products not only contain heavy metals, still contain lead, cadmium, tin, etc., but because there is such a layer of enamel, not precipitation, so as long as these harmful elements won't be a threat to the health of human body. The firing temperature of enamel products after porcelain plating is about 700℃, so its chemical properties are not stable. If a good enamel cup contains acidic beverages such as carbonation, orange juice, lemon juice, or hot coffee, it will release excessive amounts of lead, of course, enamel products can not be heated. There are damaged, more can not be used, precipitation of harmful matter is simply... Not too much. If there are enamel appliances in the home, it is best not to store acidic substances in the enamel appliances, of course, overnight leftovers are not put into the enamel appliances, easy to produce acid and enamel reaction, and then precipitate lead. Daily HAD BETTER NOT LEAVE OVERNIGHT food, even if tableware safety won't react with food, eat to the body is not good. Acids include vinegar, coffee, citrus drinks, tomato juice, pickles, sugar water and so on.

Ceramics are appliances made by glazing a porcelain slab and firing it at a high temperature. Ceramic high temperature firing also determines its chemical properties are more stable, not easy to react with acid, of course, here is also qualified ceramic tableware, they can not be very good at identifying ceramics, you can buy tableware in the formal channel. The heavy metal of ceramic cup is also in the pattern pigment, so you can choose the underglaze color, the glaze color, if you choose the glaze color, you can choose the manufacturer you trust or have a brand, the best place to contact food is not decorated. Once cracks appear on the surface of the porcelain or the porcelain falls off, it should be discarded. Because hazardous substances such as lead and cadmium are likely to be released from these places, the health of the family will not be guaranteed.
