Here's a new one I haven't tried yet. I've seen someone do it on Youtube. As I understand it, it involves pouring two colors alternating in fairly small quantities into a loaf pan. Should I pour for penetration or from low altitude? I'm going for traditional tiger colors. Thinking natural soap with the alternate orange coming from a combo of tumeric and tomato paste. This will be my first experience with "spice rack" colorants. I use mostly oxides, but I haven't had much luck with brick red and yellow oxides in achieving orange. Any words of wisdom on the process? The planned fragrances will be from orange 5x and sandalwood.
