So, I know most of the questions here are chemistry and biology oriented, but I have a manufacturing question. I'm seeing a lot of lovely pressed powders where a scene or design of some sort is created out of different colors of powder. All I know about powder pressing is something like: Make liquid-goop. Put in pan. Squish with stamp. So how the heck do they get the powder goop to make these beautiful designs without just blending together.
No practical application here, just searing curiosity!
I'm talking about something like this, http://www.musingsofamuse.com/2011/08/victorias-secret-hypnotic-beauty-luminous-blushhighlighter-review-photos-swatches.html, where the reviewer notes the pattern runs all the way through, so it is not simply a multi-colored stamp on the top.
