Pressed my minerals using only 90% Isopropyl Alcohol (rubbing alcohol). Don't get your vodka out for this! You'll also need a sterilized quarter wrapped inside a regular T-shirt for that catchy pattern and it soaks up the excess alcohol when you start pressing. An eyedropper is handy when adding alcohol to the mix in a 5g sample jar. Three-quarters of a sample jar should be suitable for pressing in a 26mm pan. A couple of bent up bobby pins for stirring and spreading is also needed as well as a massive amount of paper towels because the activity is super messy folks!
You'll need empty eyeshadow pans and a palette to put them in (e.l.f. Elements compact for $1 is what I used). And did you know I'm a germ freak so I scrubbed that quarter as good as I could with soap and water and let it soak in the alcohol. I would have flamed it also after the alcohol because I remember we used to sterilize our loops like that in Microbiology. But that's another story.
These matte minerals hold up much better than the shimmery eyeshadows that I pressed before. Here's a link to my video.
Here are the swatches:
