candle glitter?

[twinklebella.livejournal.com]

do you need a special kind of glitter for use in candles, or is it ok to simply use ultrafine glitter?

I've been searching online and it seems that its just cosmetic/ultrafine grade glitter, but I'm using it for the wedding favors for my sister's wedding (pictures to come!) so I just wanted to make sure.

thanks!
