Mineral make-up filler round up (with iron oxides): Bismuth oxychloride

Bismuth oxychloride is supposed to offer good coverage, good shine (too much for some!), and good adhesion. It plays well as a filler in micas, so let's see how it works with matte pigments.

As you can see, it doesn't do much. At 1 cc colour grind to 1 scoop (0.15 cc) bismuth oxychloride (13%), there is no colour change or sparkle. For some reason it looks darker in the chart above - that was a trick of light or camera goblins or something - but nothing really changes. The slip and glide is just terrible.

At 1 cc colour grind to 2 scoops (0.30 cc or 23%) bismuth oxychloride and at 1 cc colour grind to 3 scoops (0.45 cc or 31%, over the maximum recommended usage), it's pretty much the same thing. No real colour change, no real sparkle. It is a bit more slippery, but the colour is so intense, I don't think anyone who doesn't work by dark of night would wear it!

Again, I was surprised to see how little the colours changed considering what 43% was like in the mica blend. I think it's all about the shine - the matte pigments offer no shine, so the bismuth is the only shiny ingredient in the mix. The adhesion was decent enough, but I wouldn't use something so grippy on my eyes!
