How to judge the quality of ceramic coffee mugs by watching and listening

From Xinxiang Ceramic Mugs Manufacturers,How to judge the quality of ceramic coffee mugs by watching and listening.

In daily life, we deal with ceramic tableware every day, so how to identify the quality of ceramic coffee cup? The two most important keys to distinguish ceramic tableware are "look" and "listen".

1. "Look" is to observe the inside and outside of the ceramic coffee cups carefully. First, check whether the glaze of porcelain is smooth and smooth, and whether there is scratch, small hole, black spot and bubble; second, check whether the shape is regular, and whether there is deformation; third, check whether the picture is intact; fourth, check whether the bottom is flat, and must be placed stably, without burr.



2. "Listen" is to listen to the sound when you gently tap the ceramic coffee mugs. If the sound is clear and melodious, it means that the porcelain body is fine and dense without crack damage. When it is fired at high temperature, the porcelain is complete. If the voice is dumb and dull, it can be concluded that the porcelain body is cracked or incomplete. This kind of porcelain is easy to crack after cold and hot changes.



In addition, do not buy Ceramic tableware with too bright colors. In order to make the color bright, the manufacturer will add some heavy metal additives to the glaze color. Therefore, the brighter the color of the tableware, the more likely the heavy metal will exceed the standard. Long time use of such tableware will cause chronic poisoning.



Recently, I saw a lot of people saying bad things about custom ceramic coffee mugs  on the Internet, saying that ceramic tableware is not good and contains toxic substances, which should be used as little as possible or not. I think people who say these words are all idiots and lack of common sense. People in the United States and Europe regard ceramic tableware as a symbol of family life, but some people here don't understand anything and say that ceramic tableware is poisonous. They are really angry.
