LIQUID CRYSTAL FORMULATIONS
LIQUID CRYSTAL FORMULATIONS
Thermochromic Liquid Crystals (LC s) are optically active mixtures of organic chemicals that can be highly temperature sensitive and change to many colors.  LC s start black below their temperature range go through the colors of a rainbow and then black again above the temperature range.  LC s are reversible so they can be used over and over again.
