What is the technique?
Thermochromic inks can change from colourless to colourful or colourful to colourless very quickly. Although thermochromic inks were introduced in the 1970s, they are used extensively today.
What are the relevant materials needed for the technique?
- Thermochromic Powder
- Clear Base
- Acrylic paint
- Cup and Spoon
- Silk screen stencil
- Squeegee
- Fabric
- Mask
How to achieve the technique?
- Wear mask.
- Mix 1 spoonful of thermochromic powder to 5 spoon of clear base in a cup. (If different colour is desired, add acrylic paint to the mixture)
- Ensure the mixing is even.
- Iron and put the fabric on the table.
- Lay the mixture on the top of the stencil evenly.
- Use squeegee to push the mixture through the stencil.
- Repeat step 6 a few times until the design is clear, checking that the printing is even by pressing the fabric down while slowly lifting up the stencil.
- When printing is completed, hold down the fabric and remove the stencil.
- Let dry.
*Note* When printing T-shirt or double layer fabric, remember to layer a piece of paper, cloth in between the back and front to prevent seeping.
What are the uses and applications of the technique?

Own personal reflections
I find this technique very interesting as the pigment changes colour according to temperature. I believe it can be use to create very interactive design such as on toys,clothing,mugs or furniture.
This method reminds me of the packaging of Meiji Yan Yan Sprinkles Biscuits, where through rubbing reveal the answer to the quiz printed on the packaging.
