Description
Note: Cold Temperature Color Change needs to use ice water.
Specification:
Material: Ceramic
Size: 9*3.8cm
Cold-change cup: Cold-change requires ice water to change color, hot water at room temperature cannot change color.
The lower the water temperature, the stronger the discoloration effect, and the longer the discoloration time [Ice water below 18 degrees is the best]
Heat change cup: Heat change requires hot water to change color, but ice water at room temperature cannot change color.
The higher the water temperature, the stronger the discoloration effect and the longer the discoloration time [hot water below 50 degrees is the best]
Features:
Their principle is: temperature-sensitive materials are printed on the cup body, the materials used are heat-sensitive materials, lead-free.
