I made soap last night using the walmart recipe (with GM) and prairie fragrance dragons blood. I put it in the oven. :/ Everything was normal till I went to cut it today and the outside top and bottom edges are a really dark brown and the inside of it is light tan. Did it heat up to much? Not enough? Is it ok to use? This hasnt happened before what should I do so that it doesnt happen again (cover with towel?) Thanks in advance.
