Thermochromic ink

Thermochromic inks can change colour and turn invisible / visible upon contact with heat.

 

Materials needed:

  • Thermochromic pigment
  • Silkscreen medium
  • Fabric
  • Screen
  • Squeegee

Steps:

Mix some thermochromic pigment into a cup of silkscreen medium (approximately 5 scoops of medium to 1 scoop of pigment). You can add acrylic paint colours to create your desired hue. Pour the mixed solution onto the screen and screen print onto fabric. Leave to dry.

Applications:

Mugs, clothing, drink cans, furniture

Reflection:

This is a relatively easy technique to achieve, and encourages interactivity. Thermochromic inks could potentially be used in exhibitions where users can come into contact with an artwork and see it change in nature almost immediately.
