Art 'N Glow's thermochromic pigment collection features premium color changing powder that reacts to heat at 82°F — transitioning from a vivid color to clear, or shifting from one color to another entirely. Available in 19 colors across two types: color-to-clear (the color disappears with heat, revealing whatever's beneath) and color-to-color shift (one vivid color transforms into another). Both create genuinely interactive, surprising results in finished projects.Mix our thermochromic powder for resin to create color-changing coasters, mood-ring-style jewelry, and resin art that responds to the warmth of a hand. Our heat sensitive powder also works beautifully in slime, acrylic paint, wax, nail dip powder, fabric dye, and cosmetics — any medium where the magic of color change can be seen and felt. With particles under 10 microns, it's fine enough for most spray guns and airbrushes. Each color switches thousands of times without degrading.Each 20-gram bag of temperature sensitive pigment comes in a resealable bag, is non-toxic, and is waterproof for use in water-based mediums. Transitions at 82°F. Compatible with Art 'N Glow Clear Casting Epoxy Resin and all resin brands. Note: ambient temperature affects color change — cooler environments produce the most dramatic results.
