Testing purple micas

This will be the last part of the mica colour tests for now. The colour purple has always been a difficult child of the colour family. It is hard to achieve with blending, because as you know purple is made with the two primary colours red and blue, but the undertone of the soap has yellow, which often leaves a rather muddied grey colour than the pretty purple you aimed for. This is one reason many soap makers turn to micas for the colour purple. However, not all micas perform well in cold process and purple is a particular colour prone to disappearing. If you want to know what I mean when I talk about colour disappearing, here’s an example.

I tested the three purple micas Pure Nature has in stock: Magic Violet, Silken Violet, and Dark Violet Purple. And here’s how they the performed in cold process soap:

Luckily, none of Pure Nature‘s purple micas disappeared, although the Dark Violet Purple did turn a dark grey, but the other two micas produced very pretty similar purple/violet colours.

I even found that one of them, Silken Violet, stayed fairly true to the colour of the mica in powder form. I think I may have a new favourite colour!

What can you expect this week in tutorials? Since I started this colour testing, I knew that when it was purple’s turn, I wanted to show you how to make gemstones out of melt and pour. So one of the tutorials will be to produce very pretty, sparkling amethyst soaps. The other tutorial will be a cold process soap, which will show you how to produce fine line swirls in soap. Check back for these tutorials and Happy Soaping!
