I have WSP's Cobalt Blue Ultramarine Powder. I've used it a few times, in both HP and CP soap. Until now, it's been totally reliable, always producing a nice blue in line with the amount that I used.
This weekend I created a set of TARDIS soaps. I scented them with a mixture of almond biscotti and raspberry cream oils to mimic a bakewell tart, and did an in-the-pot swirl, 2/3 ultramarine blue, 1/6 oil-mixed TD and 1/6 Americana Red Oxide. It went fine, aside from putting one of my ITP blobs too close to the spout and getting one soap red w/ white and blue accents. :thumbdown:
Imagine my surprise when I looked in on them a couple of hours later to find that the blue had turned a medium mint green.
I've used the same recipe w/ this powder before without any issues.
Anyone have the same experience? Or see anything that stands out as a likely culprit to you?
At this point I'm guessing it must be something to do with the fragrance oils, as I haven't used those two things together.
