ヘザー 3 It seems easier to burn than other MP soap brands I have used before. You have to be extra careful when melting it or you will have many many bubbles. It's difficult to get rid of them all. But its a very decent price, and if you add titanium dioxide or white coloring to make it opaque, the bubbles are no problem. However, if you burn the soap, that makes the final product produce less lather than normal, so again, you just have to be careful when melting it.
