Distinguish the quality of ceramic coffee mug

How to distinguish the quality of ceramic cups?

There is a four-word formula to buy porcelain, that is, look, listen, compare, try.

1. To look is to carefully observe the inside and outside of the ceramic cup. See whether the enamel is smooth and lubricated, whether there are scratches, holes, black spots and bubbles; Second, to see whether the shape is regular, whether deformation; Third, see whether the picture is damaged; Fourth, see whether the bottom is smooth, must be placed flat, no burrs.

2. To listen is to listen to the sound made when the porcelain is struck. If the sound is clear and pleasant, it indicates that the porcelain tire is fine and dense, without cracks. When fired at high temperature, the porcelain is completely porcelain. If the voice is hoarse, it can be concluded that there are cracks in the porcelain tire, or the porcelain is not complete. This kind of porcelain cracks easily when hot or cold.

3. Comparison is a kind of comparison. For matching porcelain, compare the accessories to see if the shape and picture decoration are in harmony. Especially the complete set of blue and white porcelain or delicate blue and white porcelain, because the color of blue and white porcelain changes with the change of combustion temperature, so the same blue and white porcelain, the color is deep or light, a set of several or even dozens of pieces of cold porcelain, if each piece of blue and white color has obvious difference, this set of porcelain is greatly inferior.

4. The test is the test cover, test installation and test. Some ceramic cups have LIDS, and some are made up of several elements. When choosing porcelain, don't forget to test the LIDS and assemble the components to see if they fit. In addition, some porcelain with dripping Guanyin and other special functions, can automatically drop water; Kowloon Fair glass. If the wine is filled to a certain extent, it will leak completely. So give it a try and see if it works.
