Thermochromic Pigment Color Changing Powder - 20 Grams - Heat Sensitive Great for Art - DIY Crafts - Art Projects & Party Decorations - 10+ Colors Available - (Sky Blue)

works very well with standard polyurethane lacquer. Note that the white is actually see-through, so you need to be sure that you have the background color how you would like it to appear. Great for classroom demonstrations. Also, when you put it in lacquer, the blue is much more intense than the powder appears.

I liked the light pink color didn't distract from my tumbler design, and turns a beautiful dark pink color in the sun. I actually bought this as a mistake, I wanted on that changed with heat, but and super happy with the UV color change!

I teach a slime and science class during the summers, so of course we had to make heat sensitive slime. It was a huge hit. It didn't change on contact like I thought it would, but slime is pretty cold. You have to use a little at a time and really work it in your hands for it to turn colors. Overall SUPER fun!

Good colors, fast changing, and looks good at any saturation. Color mixing is predictable and provides excellent results. The only problem is that it quickly fails with UV exposure, as expected, but choose a resin or coating that blocks those high-energy photons.

Kids loved seeing their slime turn from a bright orange to white as it warmed up in their hands. Smaller pieces turned white even sooner. It's a small baggie but a little goes a long way. I didn't need to use a 1 to 20 ratio to get it to work. It was more like 1 to 50 ratio in the slime.

I purchased the red to yellow powder. Based on other reviews, I figured this would be fine for slime (I was tying it into a class on reptiles and heat transfer). However, it dried our hands out BAAAAD… like my hands were peeling. I definitely didn’t use very much in their slime at all. The same slime recipe without the powder was fine. I’ve used other powders from other companies just fine in the past with success, and no peeling hands … I don’t know what was up with this specific one. The color change wasn’t as drastic as I hoped, but was there. More of a color change to a pastel orangey, slightly yellow. I still have plenty of this baggie left, but I’m going to go a different route next time.

It worked great. My daughter was so excited to make slime with it. The color was vibrant and changed to a beautiful pink when it was heated with her hand. She was so excited, wee took a video and posted it on her class website. We're definitely ordering more in the future.

Was looking to try a peekaboo effect with some epoxy, but the color doesn't change unless extreme heat is applied and once it dies it goes white- not clear as promised. What a let down for my molds
