Thermochromatic Pigment - Rose Pink (20g)

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.

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.

Used this for a color changing goo at work. The kids really liked it.Just need about a teaspoon of this, 1/3 cup of clear glue and about 2 tablespoons of laundry starch.

I got purple/teal, used it to make slime and it was amazing. Mixed with clear nail polish it is actually almost emerald green at body temp and deep purple in ice water! Definitely won't be running out anytime soon, either.

I love the UV sensitive pigment for homemade slime but this is the bomb when it comes to play dough additives. It would describe the color more purple to pink when adding to a flour dough, but regardless my kiddos were really taken with this.

Does it work? Yes.Used in slime. It does not react to your touch. It will only change when blasted with a blow dryer, ran under hot water, or sat in direct sun.So it is not as cool as we were hoping since playing with it, it just stays one color in your hands.

This pigment powder works well in resin. I’ve had no problems with it. The product is well worth the price.

This was a good set of pigment that does eventually change color, but it takes a lot of heat to get it changed if mixed into slime. The purple color is very good and the powder is very fine, so it mixes well. It all comes in a zipper pouch so you can use a little and reseal if needed.

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
