A thermal polish - Black when cold changing to a dusky grey/blue when warm with underlying holographic sparkle. Shown here with 2 coats & topped with Elite Top Coat.
Swatched by myself.
The thermochromic pigments I use are heat sensitive and will change from one colour to another at approximately 30°C.
Thermochromic pigments are active for up to 12months. Colour change may not be as evident after this time.
To prolong the life of your thermal polish, I suggest you store bottle in a cool/dark environment, as this preserves the pigments.
