Color Changing Photochromic Pigment Powder - Changes Color in Sunlight & Changes Back When Sunlight is Blocked - 5 Grams (White to Yellow)

Works ok! For these for resin projects and I've found that yellow photochomatic powder can be hit or miss, just because it's lighten than other colors so the change is less obvious. You can definitely are a change, I just wanted it to be more WOW. I might try different ratios of powder to resin to see if that makes a difference. The thing I don't like is the container- they don't some in the pictured container which would protect them from UV light when not in use. They come in labeled bags, but the containers themselves are unlabeled and clear. So I've labeled them myself and store them in a dark box when I'm not using them to extend the life.

Came in completely different container unlabeled.

jars were not labelle4d like this at all, evidently an artists rendition perhaps, but nott he actual jars, and i used quote a bit in my resin for dice and they BARELY changed under intense uv light even. save your money and buy it elsewhere.

Had high hopes and lots of visions for this product. But it is light yellow - NOT WHITE - when mixed. It does turn a nice blue but if you are looking for white - then blue - it's not for you.

This absolutely does not work with any kind of epoxy. I’ve tried with two brands of tabletop epoxy, and two brands of deep pour epoxy. Total waste of money

Does nothing!
