How Do Heat-Changing Mugs Work?

So, How Do Heat-Changing Mugs Work? These magical mugs use thermochromic pigments in their coating. When hot liquid is poured in, these pigments react to the temperature change and reveal the hidden colors and designs. As the mug cools down, it goes back to its original look.

  • Thermochromic Pigments: These pigments are temperature-sensitive, causing the color change effect.
  • Heat Activation: Pouring hot liquid activates the pigments to display the hidden colors or designs.
  • Cooling Process: As the mug cools, the pigments revert to their original state, ready for your next hot beverage.

Fun Fact: The science behind heat-changing mugs adds an exciting element to your usual coffee or tea routine.
