Ceramic color changing mugs, as the name suggests, are cups that can change colors. This change of color is generally based on the change of temperature to change the color of the cup. Ceramic color changing mugs are divided into thermal discoloration, cold discoloration and water discoloration.
When the temperature of the thermal discoloration is above 40°C, the color will change, and when the temperature of the cold color change cup is below 20°C, the color will change.
Have you ever seen a mug that changes color? This color changing mug looks very ordinary, usually only one color, black, blue or other colors. But when you pour hot water into a color changing ceramic mug, something magical happens.
As more and more hot water is poured in, the color of the ceramic cup itself will slowly disappear, and a pattern will appear. The pattern could be a cute cartoon character, a beautiful landscape painting, or even a picture of you and your family.
After a while, the water in the ceramic cup became cold. The pattern on the cup slowly disappeared and returned to its original color.
Why can the color of this cup change? The color changing mugs have an extra layer of temperature-sensitive coating made of heat-sensitive materials than ordinary cups. Thermosensitive materials are materials that are greatly affected by temperature. This material will change from one color to another according to the change of temperature.
Production Process of Color Changing Mugs
Although it looks amazing, the process of making color changing mugs is not complicated at all.
In the first step, we need to prepare an ordinary ceramic cup and the heat-sensitive material just mentioned. Grind heat-sensitive materials into small particles, add water and stir evenly, then apply to the outside of ordinary ceramic cups, and put them in the oven to bake.
The second step is to print the favorite pattern or photo on the special heat transfer paper, paste it on the surface of the cup just now, and heat it in the oven. After a few minutes, the picture on the sublimation paper is printed on the ceramic mug.
After completing these two steps, a color change ceramic mug is ready. When hot water is poured into the cup, the heat-sensitive coating will become transparent, and we can see the picture printed in the second step.
