For a detailed explanation of the functioning and applications of thermochromic pigments see the TEP Smart Colors info sheet (PDF) and this little demo animation.Heat reactive materials change state, shape and/or color when exposed to temperatures above ambient. In this post I’ll go over thermochromic pigments and a few materials they have been incorporated into, namely paint, fabric, film and glass. What’s special about some of them is that their state, shape and/or color can be altered at relatively low temperatures (provided through hot water, body heat, hair dryers, ambient heaters, ovens, or just a hot summer day), making them easy to use and suitable for DIY projects.The textured glass surface layer protects and highlights the color-change film on the tile.The base color of the tile can match almost any color, and the temperature change point can be fit to the userâ€™s environment and requirements.For more information on Francisco’s experiments, check out this report (pdf).

At specific temperatures the liquid crystals re-orientate to produce an apparent change of colour.
The liquid crystal material itself is micro-encapsulated – i.e., contained within microscopic spherical capsules typically just 10 microns in diameter.
At room temperature the pigment appears in its original color, but at temperatures between 27Â° and 30Â°C (80Â° to 86Â°F) this color disappears, eg, if a black pigment is applied to a white surface, the surface turns from black to white at the change-over temperature.
When mixed with an acrylic base each pigment will turn instead into the color of the acrylic base or color blender, eg., if a blue pigment is mixed with a yellow acrylic base the resulting color will be green, but at the change-over temperature the blue will disappear and the green will turn into yellow.
The dynamic color change begins at the selected activation temperature and shimmers through three phases, one with each 6â€“10Â° rise in temperature.
