Thermochromic ink reacts with heat. When heat is applied, the ink turns transparent. When cold air is applied, the ink reverts back to its original colour. For thermochromic ink making, we mixed 2-3 parts of Beta with 1 small spoon of the thermochromic powder then mix the mixture up. Then, we used silk screen and applied it to our fabric. The paint dries quickly and the thinner the layer, the faster it disappear when heat is applied.
