First, the ultramarines and oxides:
These colors were fairly predictable. I mixed the powders with distilled water. I also wanted to do samples of these colors mixed with titanium dioxide, but I didn't have enough containers.
Next up, some liquid colors I had on hand:
I believe these are meant more for melt and pour soap, but I wanted to see how they would react in cold process. The red stayed pretty much red during the cold process. The green colorant changed to a shade of light olive green when first mixed with the raw soap, then as it went through gel it turned almost as red as the red color and then finally settled on a nice salmon color once it cooled.
I also did a sample of pink mica and purple mica mixed with distilled water. I didn't take a picture of them, however the pink mica stayed pink, but the purple mica instantly turned pink in the raw soap as well. After going through gelling they were almost identical in color and very similar to the red oxide, perhaps just a shade lighter and more dusty.
So, what did I do with the leftover colored soap?
I made more soap, of course! Fireworks soap in honor of the fireworks we saw yesterday for Canada Day :)
The soap was at a really thick trace by the time I got it into the mold; I had to spoon in the colors and swirl with a chopstick to get any blending done. I think it turned out really pretty, but I don't think it's something I could replicate very easily!
