Steel Works Silver-Black Mica


Regular price $ 1.50

Sample bags contain one generous teaspoon (approx. 3-4 g).

Strong. Solid. That's what comes to mind when you see this deep, bold steely grey mica. The really cool thing about this mica, though, is the fantastic glittering iridescence that you see when the light hits it.

The juxtaposition of the twinkling rainbow of colors and the intense, industrial grey has a serious wow factor. Seriously.

Soap Notes

Usage rates in Cold Process soap: 1-2 tsp. per pound of oils.

Usage rates in Melt & Pour soap: 1/4-1/2 tsp per pound of M&P base.

Adjust these calculations to lighten or darken your desired hue. These amounts create bright colors with no colored suds.


Bath Bomb Notes

To use in bath bombs or other water applications, you must use polysorbate 80 (emulsifier) at a rate of 1-2% of your total batch weight. This should disperse the color evenly and eliminate mica from floating on the water's surface or leaving a ring of mica around the bathtub.

This is so much better in person! The perfect color for my UFO bath bombs. The lights were colored with Lemon Cupcake, over the Steel Works.

Love love love!

I used this steel works Mica as a dark silvery gray base in cold process soap. It blended beautifully and provided consistent color throughout the loaf. Will definitely purchase again!


I purchased this specifically to paint the eyes on my kid's dinosaur soap collection and it was even better than expected and my customers love it. Going to need to purchase this one over and over! Another home run from Mad Micas!!!

Great color!

This has a great color! Its much better than the old black i was using because it has the steel look to it. Definitely reccomend this color to anyone!

Massive sparkle

This is such a perfect true dark steel gray. The shimmer in this is stunning and it looks absolutely stunning in soap. LOVE it
