Is it harmful to drink hot water from a ceramic cup?

Ceramic cups are cups made of ceramics, which are environmentally friendly, durable and practical, and are widely used in modern life. Ceramic cups can generally be used to hold boiling water, because ceramic cups are fired at high temperature, high temperature will not affect the ceramic cup, and will not release harmful substances due to high temperature, so drinking hot water with ceramic cups will not be harmful. Harmful to the human body; however, it should be noted that some inferior ceramic cups are of poor quality and may shatter when used to hold boiling water.

As a type of ceramic products, ceramic cups need to be fired at high temperature. Even low-temperature ceramic cups need to be fired at a high temperature of about 700-900 °C. Therefore, high temperature will not affect the ceramic cup or damage it. The decoration of the surface, boiling water in a ceramic cup will not have any effect.

However, it should be noted that when some inferior ceramic cups are filled with boiling water, there may be bubbles inside and the wall of the cup has a certain thickness. When pouring boiling water, the temperature of the inner wall will rise first, the outside will remain unchanged, and the thermal expansion rate will be different, which will cause extrusion. , causing the ceramic cup to shatter or explode.

Ceramic cups transfer heat slowly, and generally have handles, so many people use ceramic cups to drink hot water, but some friends have heard that drinking hot water from ceramic cups is harmful to the human body, so is this true?

In fact, ordinary colorless ceramic cups used to drink hot water will not release harmful substances due to high temperature, and usually will not cause any harm, and because of the relatively strong thermal insulation performance and high temperature resistance of ceramic cups, it is used for It is very suitable to drink hot water; however, it should be noted that there are also some inferior colored ceramic cups on the market, and the pigments in them may fall off due to the high temperature of the water. Such cups are not suitable for drinking hot water.
