Review on 🎨 24-Color Transparent Non-Toxic UV Epoxy Resin Pigment: Concentrated Dye Liquid for UV Resin Coloring, Resin Jewelry Making - Ideal UV Resin Colorant for Art, Paint, Crafts - 0.35oz Each by Wendy Rodriguez

Only half of these pigments can be used with UV resin. I tested the new mold and used the Rose Quartz dye with two different brands of UV resin. Both turned yellow on curing. I then applied a drop of each colorant to the tile and "cured" it, and the colors have not changed. I then added some UV resin to each drop and after curing 13/24 it was either yellow or gray. With these dyes, some reaction occurs when the UV resin cures, causing half of it to become fully unsaturated. Make sure you test before you potentially mess up your project and waste time. Yes, they are easy to use and transparent. When you mix them with white they are opaque - white isn't pure white, it's almost opaque; You need a very strong light behind it to see light coming through.
