This auction is for 10 grams of Black to Blue/Grey Ultra Thermal-Dust™ from SolarColorDust.com with activation temperature of 86F (31C).

Ultra Thermal Dust!™  is a thermochromic or "heat sensitive" pigment that changes its's color at 86F and warmer. 

Your hand's heat is warm enough to make this pigment change color before your eyes!

Ultra Thermal Dust is great for use in many mediums, including resin, epoxy, paint base, lacquer, glue, gel, varnish, clear coat and other bases. 

 Mixing Ratio: Use 1 gram for 4 fluid ounces of base (the size of a school glue bottle). You can mix 10 grams to 16oz - 1 liter of base. 

 NOTE: Ultra Thermal Dust is heat sensitive and can change color several times over, however, keeping Thermal Dust in the sun over time will create a "sunburn" on the pigment eventually causing it to cease changing color.

Please check our website out for several video demonstrations and for many other color changing materials!
