What would you do with composite mica?

I’ve used sheet mica once, in a mixed media jewelry making class taught by Susan Lenart Kazmer, and always figured if I found some cheap I would buy it to play around with.

So I bought a package of “composite mica” not realizing that it doesn’t work the same way sheet mica works.

What do I do with it? Anyone out there use composite mica in their crafting? It looks like it would be fun to play with, but I’m not sure how to use it….
