Description
Hydrochromic pigments change colour when exposed to water. This version is a reversible pigment which works by forming an opaque film that covers a coloured image or pattern. When the film is exposed to water it becomes transparent and reveals what is hidden underneath - thus appearing to change colour. As the film dries it returns to it's opaque state and covers up the image or pattern.
- Size: 50ml.
