Liquid Crystal - Thermochromic Ink (Mood Ring effect)
Liquid Crystal is the raw material found in mood rings and LCD screens. The material changes multiple colors based on reaction to heat. For best results the ink must be applied over a black background, otherwise you will not see the color change as well.
Best for Science Projects and demonstrating thermochromism.
Protect with Art Resin or Model Master's clear gloss enamel (both sold separately on this site) to protect from elements which can cause damage to the color change effect.
