The Science of Thermochromism
Thermochromism is a fascinating process that occurs due to the molecular structure of certain pigments. Here’s how it works:
-
Molecular Structure: In thermochromic materials, the color change is usually due to the movement of electrons within their molecular structure. When these materials are exposed to heat, the energy caused by the increased temperature can modify how light is absorbed or reflected.
-
Color Transition: Typically, color changes occur when the temperature reaches a certain threshold. For instance, when a hot liquid is poured into a color changing cup, the increase in temperature triggers a transformation in the pigments embedded in the cup. This can result in a change from one stable color to another, or even to a transparent state.
Examples of Thermochromic Pigments Used in Cups
Starbucks utilizes a variety of thermochromic pigments, which can be categorized into two main types:
- Reversible Thermochromic Pigments: These pigments return to their original color once the temperature drops below a specified point.
- Iridescent Thermochromic Pigments: These pigments exhibit a gradient of colors based on angle and temperature, creating a unique visual effect as the cup changes temperature.
