With Ralph's key rings and other things. Casting resin pen blanks, which I'm going to try.
Finding a supplier of materials to use, I went through my bookmarks and came up with a couple along with some that came from a pen forum.

Now some are cosmetic material suppliers that will deal with craft/hobby buyers. Coastal scents was the darling of the pen making community. But it sounds like to many jokers were calling with dumb to the company question. As I told one of the members that e mailed me. They don't do casting with resins, how are they supposed to answer you questions. Since they deal with do it yourself make-up!
I have just ordered form coastal scents and awaiting delivery of the mica/glitter powders. The others have waxes, and other materials that are used for making your own paints,stains etc.
I will say that most if not all of the so called mica powders and glitter are synthetic polyester material mica's. The glitter also is made of polyester material base.
Now another heads up if you are going to add it to resins or mix up colorants, or patina's. Read the info and the detailed info as some of the powders are formulated for use in water base or oil base and don't work well with the opposite.
It is amazing me how many people, attempt to do things that they don't have a clue about, and then whine when things go wrong. Like using water mix powder paint and it doesn't do anything but clump, and the resin doesn't cure due to the PH being changed and the water they mixed in with the paint to liquify it.
Your wife may have some raised eyebrows as the make-up suppliers put silly sticker on the package like Lipstick addict, you also may have to hide the material when she finds out she can make her own, make-up .
PS: almost forgot, the earth tone and mineral powder bases, are the same stuff that they sell at top dollar for Model RR weathering, along with military modelers and diorama doll house builders. The sample packs will give you a lot of use with smaller cost!
