Identify the quality of ceramic cups

Four methods to identify the quality of 0.2L ceramic beer mug:

1. Whether the lid fits properly.

Ceramic LIDS help the water cool less quickly, and if the lid doesn't fit properly, it could be defective and affect future use.

2. Listen to sound.

Finger flick, if issued crisp, pleasant sound, then this porcelain tire is fine and dense, if the voice hoarse, then for inferior porcelain, can not be bought.

3. Look at the pattern.

When drinking water, the mouth will touch the cup wall, so the top outside of the cup wall, that is, the mouth contact place should not have a pattern, and the inner wall should not have a pattern. Because these glaze decoration contains trace lead, cadmium and other heavy metals, it is not easy to use for a long time. It is harmful to human body.

4. Touch the surface.

See if it is smooth, see if there are cracks, holes, black spots, if it is as smooth as glass, the product is better.
