Thermochromatic Pigment 22C/72F - Purple to Pink(20g)

Description: We've all seen toys and things that change color when you run them under warm water or heat them up in the sun. This is a property called 'thermochromism' and it can be implemented in a number of ways. This particular thermochromic pigment is a Leuco dye type pigment which is made up of a mixture of Leuco dyes, weak acids and salts microencapsulated in polymer.

This Pigment was specifically formulated for colder areas or where room temperature is below 70F

This is a very fine, colored powder that changes to a secondary color when you heat it to about 72F (22C). This is really cool for a lot of reasons. You can mix this pigment with paint to create thermochromatic paint for craft projects or to make temperature indicators. It mixes with Slime and Polymorph as well, rendering them both thermochromatic. Use a controllable electric heating source and you could even build a thermochromatic display!

This pigment comes in a 20g bag, which is more than enough to play with and just enough for a good sized project (depending on what you're doing with it). Careful not to overheat the pigment as temperatures over 200C can cause irreversible damage to most Leuco dyes.

Features:

• Blue at Room Temperature
• Turns Beige at Around 72F (22C)
• Mix with paint, glue, resin, Polymorph, Slime, etc.
