Product Description
Temperature Activated
This thermochromic pigment changes at 88⁰F (31 ⁰C) from colored to transparent/white. It is darker colored below the temperature and lighter colored above. This temperature range makes it perfect for changing color when touched.
To use this powder, simply add it to a clear base and mix well. Keep in mind that mixing generates heat which may temporarily change the color of the mixture. It is recommended to start with a very small amount of pigment and add more until the desired color is achieved. A ratio of 1 part pigment to 20 parts base is a good starting point.
Note: The pigment may be warm from shipping. For best results, refrigerate for 1 hour prior to use.
Non-Toxic Powder
This pigment powder is safe for skin contact and uses no harsh chemicals (but not intended for consumption). This makes it great for color-changing slime, play dough, Sugru, Polymorph, and nail polish.
High Quality and Versatile
This thermochromatic powder is ultra-fine with vibrant colors, meaning it's great for mixing and disolving into a variety of media, including paint, glue, nail polish, slime, etc.
A variety of equally vibrant colors to choose from for all of your project needs. For a wider variety of colors, consider mixing the primary colors (red, yellow, and blue) to form any hue you need for your project.

It worked for a few days (kind of) and now it’s not blue at all

Most of the thermochromic powder (color changing with heat) I've gotten has been very similar, for all I know it all comes from the same factory.This is *31C (~88F)* color changing, meaning it will be black most of the time, but change to white (or clear, in liquid) under heat (body heat, hair dryer, etc). This is good for covering secret messages that reveal with heat.Applying the powder is a bit tricky. You have to mix it with some kind of clear binder base. You can get acrylic base, or just use clear-dry (Elmer's) glue of some kind. The powder doesn't "want" to mix, you're going to have to spend a minute beating each batch into the base. You'll need to experiment with the right ratio, but start with something like 1:8 (powder to base, by volume) and adjust to minimize powder consumption while still applying in an opaque coat.It's also available in other temperature-thresholds (instead of 31C) and colors (instead of black-to-clear). While this worked OK, for use on paper I found it inferior to a proper thermochromic *ink* as made by Atlanta Chemical. Your mileage may vary!

I've had a bad batch before but overall it's a great product. The replacement for the bad bag was here in two days and worked . I have to use more pigment to binder ratio(1:1) than I originally was told (20:1) ...BUT I found this specific brand way better at becoming completely transparent more than some of the others on Amazon . I have bought the Black to colorless and the magenta to "colorless" . Black is perfect but magenta turns into light pink not clear. Like ever... No matter how much you mess with the ratios it never turns clear ,BUT it's still pretty .

This powder works in resin casting/epoxy. The color difference is noticeable and the color is as described. Not sure why people complained about the size of the product. A little goes a long way. I used 1/8 teaspoon of powder in 60ml of epoxy mixture and got 4 keychains and a set of earrings.

I never knew this powder existed and now I want to put it in everything. My niece and I made slime and it went splendidly! It was a definite upgrade for the slime and made for a fun science experiment feel. We've made two batches and there's still so much powder left.

Well since the day was so hot with this summer heat I didn't see much of a color change removing it from the package. So I took a frozen bottle of water and set it on the package and the color change happened. It is a good product will be buying more.

For my projects I tried mixing the pigment with gloss varnish and print ink extender. Both instances the pigment mixed very well with the mediums and reacted to temperature once dried. I was worried that it wouldn't react to a person's hand, but it did change color. Just be careful when working with the powder because it's very fine and easy to get everywhere if you're not careful. A little goes a long way!
