I'm curious about titanium oxide as well I have a bag but only made 1 test candle. I mixed it with the soy wax. So far it burns clean and seems to hold a pastel color but has a shine to it. Almost looks plastic.
I have candle whitener chips, they're actually powdered light blue. I have never tried it. I can't seem to find much info. about them tho. I like my candles to be as chem. Free as possible. Anyone have input on this product
