Im wondering if when using gold glitter dust with vodka or pure lemon extract will it stick to chocolate because its oil based?

Typically you apply gold dust to tempered chocolate with-out any liquid. I don't think it will adhere using an extract at all.

I usually do exactly what stiches said, and it works really well.
I did find this though, she shows a few different gold sheens all applied straight onto chocolate. http://hmhdesigns.wordpress.com/2013/02/20/chocolate-oscar-statues-luster-dust-testing/

AGreat!! Thanks so much for the help :)
