Sometimes the most stunning soap projects come from a simple design idea. This Spiced Copper Cold Process features layers of uncolored soap separated by lines of Copper Sparkle Mica. The top is then covered in the mica, creating a sparkly and slightly rustic look. This soap is scented with Spiced Amber Ale Fragrance Oil, which does not discolor in cold process soap.

The technique of creating lines in cold process soap using powder colorants is known as a mica line, or mica vein. The key to this technique is creating thin and even lines of colorant. If the lines are too thick, the layers of soap can separate. A small powder duster really comes in handy. While other colorants like oxides and pigments can be used for this technique, micas work best as they are extremely fine. The fine powdery texture of micas makes it easy to create a thin and even line. If you are thinking about trying this technique, now is a great time!
