I made a loaf of 100% Olive Oil Castile soap last weekand I used the dark EVOO.... at first I was kind of worried about the soap ending up dark and ukkky green colored. But, after pouring and then cutting the next day, I was rather surprised at how light it was. And, it seems as a week has gone by, it's curing up rather nicely and getting lighter and lighter. It's a pretty creamy color now. I was also afraid that it would be a rather soft bar too - but it's nice and firm. I'm rather anxious to see what it's going to look like after another 5 weeks have passed and it's completely cured.
