I wanted to know if you can use luster dust or any type of dust to design sugar bottles that are made from isomalt?

anyone have an idea?

You can use powered color IN your sugar to color it. I've never tried putting it in the mold and then pouring. It doesn't seem like that would work to me.

I think my message isn't clear enough. I want to brush on the dust after the sugar mold is made to give it a certain color. The same way the brush on a little color on the fondant type flowers.
