Thermochromatic Pigment - Orange (20g)

I bought the purple to "red" (more like pink) to make slime with my daughter. It works great! She has a nice ball that changes color when it warms up. Here are some slime hints:1. Use clear glue, not white glue2. She used the glue/sta-flo recipe3. We guessed and added 1/8tsp per "serving". This gave us a brilliant purple and vibrant pink. A little goes a long way with this stuff.4. This pigment turns color around 92F, which is below but close to your body temp. Warm bath water or pool water is like 85F, so a little warmer than that. You may need to hold it between your hands for a couple minutes. It does change color and the kids love it. You don't need to hear it in the microwave or steam or boiling water, those will probably destroy the pigment per manufacturer. A small ball in a closed hand is sufficient.

I really like this pigment but buyers should note it turns from Purple to PINK not red as listed in the description. It is an ultra fine/light powdered pigment so the 20 grams is a niced sized amount for completing at least a project or a few if they are smaller items, My only wish is that it came in some type of hard sided container you could scoop out from vs the sealable plastic bag. I find that I end up making quite a mess getting this out for use or even trying to transfer to a more suitable container for storage/future use.

We bought this product to make colored slime when teaching polymer chemistry to freshmen. It is very cool. I wouldn't say it goes from purple to red, but it is purple in the cool phase, and hot pink in the warm phase. Only a tiny amount of pigment is needed so a little goes a long way. We have each student make their own so we have them add just a pinch to their PVA solution and stir well before mixing in the sodium borate solution. Works well. I think the reason the manufacturer does not include instructions is because every recipe is probably different but when working with pigments, less tends to be more. Would buy again.

It works well independently but I found that once we mixed it into the goo for my daughters mad scientist party it barely changed color. I think the chemical reaction from the slime we created caused it to not be as responsive. The water, glue, etc. that were all mixed together kept the slime cold even after you'd held it in your hand for a while thus null and voiding it's ability to change. We still have leftovers but I'm going to save it for a different project.

As a chem nerd I love this. As a girl who likes variety I am not as thrilled as I could be. I have used the teal/clear (more white than clear), purple/"red" (hot pink), and the purple/teal. I've tried all three in clear nail polishes. They've worked, and then reached a point where they stay the hot color no matter what temperature. One glitter polish has worked and continued working and changing colors (i don't know what brand it is since it was one I bought years ago...). Having a list of solvents the pigments should stay away from would be wonderful so that they could keep functioning.

I bought this to put into slime for my daughter. She absolutely loved it the only thing I wish is that was just a little bit more sensitive. It has to be kind of an extreme cold or a decent warm in order for it to change colors. Besides that it was super fun there were no funny reactions to it on our skin and it makes for awesome slime. Thank you.

There's probably only 4 teaspoons of pigment in the bag, which seems like a lot to pay for such a small amount. It also turns from purple to pink (not red) when heat is added to it. My girls have enjoyed using it with an oobleck recipe. It does the trick!

By far best product I’ve purchased on amazon. New projects new ideas? This is your go to product, get creative and make something new with this color changing additive. Will definitely buy more worth the time and money. Thanks again!!!!

Tried using it for slime, but the colour did not change at all. Waste of money

Couldn't get it to change from blue to white. I don't know if we were missing something... this did not meet expectations

VERY SMALL NOT WORTH THE MONEY
