Blue Crystal Slime Ingredients
Below are the measurements I used for this shiny golden slime.
- 1 cup Elmer’s (or other) PVA clear glue
- 1/2 teaspoon activator solution OR [Borax powder and 1 cup water]
- 1 cup water
- mica powder (we used aquamarine from this set)
- tangerine essential oil (optional)
You know what you don’t see here? Glitter! You honestly don’t need it, but if you’d like to add it, to incorporate it after the mica powder.

How to Make Slime with Mica Powder
- Add the glue and 1 cup water together. Stir until the glue is incorporated.
- Mix in the activator (start with 1 tablespoon and add incrementally) and stir. Note: if using Borax powder, add the powder to the second cup of water first. Once combined with the glue, stir slowly until the mass forms. If needed, add a little more activating solution until the mass is fully formed after stirring.
- Stretch the slime slowly. Once it’s lost some of its stickiness, knead it by hand until no longer sticky.
- Lay the slime flat on a protected surface and add in sprinkles of mica powder. We didn’t measure, just layered it over the slime. We used about half a one-ounce bag. Slowly stretch the slime and fold in the mica powder.
- Store in an airtight container.
