Thermochromic enamel colour usually contains tiny capsules filled with special dyes or pigments that react to temperature changes. These capsules are mixed into a transparent or semi-transparent enamel.

The colour change occurs through a process called thermochromism, in which certain compounds change colour when the temperature changes. The dye molecules in the capsules are then rearranged. This rearrangement causes them to absorb or reflect different colours of light, changing the colour we see.

Overall, thermochromic enamel is a fascinating material with many uses, from decorative items to practical applications like temperature indicators and safety devices. Its ability to change colour dynamically adds both beauty and usefulness.
