What kind of ceramic cup is good

- Apr 23, 2020-

Ceramics are first divided into 1, low temperature, medium temperature, and high temperature. High temperature is the best. 2. In fact, sub-glaze, under-glaze, under-glaze, and under-glaze are all acceptable. 3. From the perspective of ceramics, the more Baibai, the better, because the whiter porcelain filter iron, the cleaner some metal mineral raw materials. The so-called purification is better. Generally choose the high-temperature glaze color. You can search for Baidu Longfa Ceramics Co., Ltd. in Dehua County, Fujian Province. This company has opened Taobao to support the purchase of scattered customers. The quality is ok.

"Listen" is to listen to the sound made when tapping the porcelain lightly. If the sound is crisp and pleasant, it means that the porcelain tire is fine and dense, without cracking, and it is completely porcelainized when fired at high temperature. Porcelain tires are cracked or incompletely porcelainized. Such porcelains are prone to cracking due to cold and hot changes.

In addition, do not buy ceramic tableware with too bright colors. In order to make the color bright, manufacturers will add some heavy metal additives to the glaze. Therefore, the brighter the color, the easier the heavy metal will exceed the standard. Long-term use of such tableware can cause chronic poisoning.
