It's not mold, it's ash. Mold can happen on soap especially if you load it up with additives and toppings that provide food for mold growth. But if this is what your first soap looks like, it's also got ash, not mold. Even tho the pic shows harmless ash, I'd suggest you leave all that stuff off the top because it could promote mold.
2/4/2015 edit -- I agree w Obsidian in Post 17 that the tea leaves are moldy.
