I'm really pleased with the way this soap turned out. There was a tiny bit of ash on top, but it wasn't too bad. I wonder if curing the loaves upside down would help this. Ash is a bit of a mystery, but I'm pretty sure it has something to do with evaporation. When my soaps ash, it's always on the top -- not the sides or bottom -- so theoretically, turning the loaf upside down would prevent it.
Of course, this is theory is based on logic, and we all know that goes right out the window when it comes to soap making. ;)
