Super quick question - will adding micas to my goat's milk be successful once the bars cure? I've made just one batch of goat's milk soap, and now that it has been sitting for two months, it's become a light tan brown color. I don't want to waste my micas if they're known to just turn brown along with the soap.

Thanks!
 
If you buy mica formulated for CP soap from a reputable supplier, they should hold up perfectly well in goat milk soap. If the mica isn't stable in CP soap it will be noted by the supplier. A lot of people have had problems with mica morphing or fading that has been purchased on Amazon, for example.

What fragrance did you use? Many of them, especially those with vanillin content, will turn the soap anywhere from light tan to dark brown.
 
Thanks, all! I don't know why my soap browned - I just assumed that must be what happens with using the goat's milk. My micas are from Brambleberry. I'll give them a try. And I love the idea of the carrot tissue oil!
I have been making goat's milk soap almost exclusively because I was overly ambitious and bought a whole a gallon at the start. I froze it all in ice cube trays and make my lye solution with the frozen milk. I have never had a recipe turn brown (during or after). I also don't insulate, but rather go cold (in the fridge) if I feel heat when pouring in the mold because I prefer to avoid gel phase with my milk recipes.
But, as mentioned above, we would need to see your recipes and know your process to know what caused the color change while curing 🤷🏼‍♀️ After all, soaping is a fickle mistress 😄
 
Can't say I know what "OP" is besides "Original Poster." Perhaps do you mean "HP" as in hot process?

If that's what you have in mind, yes, the milk can darken from the added heat from the hot process cooking. The soap will be tan to caramel.
 
I make goat milk soap exclusively. I don't oven process it, but I do insulate and put it on a heating pad to gel. I have never had it burn or discolor. From my understanding, the highest risk of burning the milk and discoloring the soap is while adding the lye.
 
People sometimes do "oven process" a batch of soap that's otherwise been made with a cold process method. Most people call this "CPOP" when talking about this method of making soap, not just "OP." So that's why you'll get confused responses like mine if you just write "OP".

I can't say I've ever heard of anyone using "oven processing" as a synonym for a hot process method.

Not everyone uses a crock pot for HP soap making either.
 
I cpop'd a gm soap that was overheating and cracking. Had purple Micas in it. It is a beautiful soap
