I think it looks great too, but I do try to avoid glycerin rivers. Search on this forum or Google. My risk factor for getting glycerin rivers is using titanium dioxide. I lower the amount of water to 1 part lye + liquid divided by total weight of lye& Laud is 32.5%
I like the way it looks, too. Manufacturers used to make their soap that way on purpose to show that it was pure soap, back when manufacturers were putting all kinds of crazy fillers in their soap to cut production costs. You can't force glycerin rivers in soap that has fillers in it. So people would look for it and pay higher prices because they knew it was better soap.
