Mica colorants can be used in everything from scrubs to soap. This week through Oct. 16th, the blog will have tutorials made with plenty of shimmery micas, like the Sparkly Garnet Soap Gems. The soap, inspired by the January birthstone, gets its sparkly red color from Merlot Sparkle Mica and Fine Iridescent Glitter. Once the soap is scented with Pomegranate and Black Currant Fragrance Oil and cooled, it is cut into fun gem shapes.
