I'm getting the silver smoke from MF, I'll look at what else they have. I've seen them before, and I believe it is just pearl powder (mica) in different pigments, added to colors. I don't know this for sure, but will soon.
I had a call with the company who makes this in its raw form and got a chance to spend some time with their technical director in this area. I'm getting some stuff sent to me from them. They have a few new products that I don't even think have made it to our industry yet. This could get pretty interesting, we'll see what they send. If there's some cool stuff I will definitely get it. My hope is we can use it in its raw form so we can have the flexibility of creating recipes - maximum creativity...
