There are three kinds of color changing cups on the market, including hot color changing cup, cold color changing cup and water color changing cup. Among them, water color changing cup has not been popularized. Cold color changing cup means that when the water temperature is below 17 ℃, the pattern of the cup body will change color, thus showing the hidden pattern.

At present, the main materials that can make cold color changing cups are ceramics, glass and plastic. Among them, glass cold discoloration Cup and plastic cold discoloration Cup are more common. The color changing principle of the cold color changing cup is that the temperature sensitive material is printed on the cup body. When the temperature changes, the pattern of the cup body will change color. The material used belongs to thermal sensitive material, which is resistant to high temperature of 320 ℃, non-toxic, harmless, lead-free and chromium free, and can meet European standards. In fact, the color changing principle of both cold color changing cup and hot color changing cup is the same, but the temperature sensing materials are different.
