Ever since our 2016 batch of Rainbow Soap has been shared around the internet, we've been getting private messages asking exactly how we got these colors. I'm going to share that information with you right now!
I'll start by leaving this right at the top. I purchased all of these micas from:
I make soap in 60 bar batches. For this recipe, each color is mica in 38 ounces of oil. Here are the colors we used, all from Mad Oils:
Purple - 2 tsp of Harold's Purple Crayon
* note - this color turned out so right and deep that next time I will try 1.5 tsp or maybe one of their other shades of purple! Harold's Purple Crayon definitely seems to be the darkest, richest purple.
Blue - 2 tsp of Key West Blue
Green - 2 tsp of The Maniacal Pea
Yellow - 2.5 tsp of Pot O' Gold - You can't tell from the picture but you CAN see golden shimmers in the soap!)
*note - My first choice was Bright Yellow Raincoat but it was out of stock when I first purchased these micas. I love the way Pot O' Gold turned out but will probably test out Bright Yellow Raincoat next time!
Orange - 2 tsp of Orange Crush.
*note - Unfortunately this specific color is discontinued (you can still get it in bulk by special order), but they have two other oranges I will consider trying next time we make rainbow soap at the shop: Tangerine Dream and Neon Orange. I will likely try the Neon Orange color!
Red - 2 tsp of Voodoo
*note - while Voodoo is more of a pink-red instead of a true red, these colors all look great together! I can't imagine this bar with any other shades of color than it currently has. I love it!
A few other notes about making rainbow soap:
- You either need to use an extremely slow moving scent blend, or you need to scent and mix each layer separately. I opt for mixing each layer separately to make sure I'm getting nice straight lines.
- Although you want a slow moving fragrance oil blend, you want to make sure the layer is then decently set before pouring on the next layer so top layers don't break through lower layers
- Pouring your layer slowly down the back of your spatula will help keep the layers from breaking through.
Here's the evolution of our rainbow soap. The Mad Oils batch is by far the best!
