Thermochromic Inks

thermochromic inks

Thermochromic powder mixed with a base can create a heat-sensitive pattern on a textile. When heat is applied to the powder, it becomes transparent and reveals the colour of the base (if the base is transparent, the ink just ‘disappears’). It can be applied just like a normal print or painted on.

In class we were provided some silk screens and block prints to play with. We used some of the thermochromic pigments in pink, yellow and black, though the black ink did not work as well as the others.
