Thermochromic mug changing colour. As the sides of the mug heat up due to the hot drink it contains,the dark dye becomes transparent,revealing the picture of a cat beneath. The dark layer contains a leuco dye. Leuco dyes are molecules that can take two forms,one of which is coloured and the other colourless. The transition occurs at a certain temperature,determined by the structure of the molecule | |
