Well, I sometimes use natural soy (in which case I cure for at least four days but have waited up to a week) and sometimes I use paraffin Problend 400 (in which case I let cure for two or three days or longer) I usually use a lb of wax at a time with an oz of fragrance and 4-7 drops of liquid dye (though once I made some soy candles without the dye - that happens to be a time that went well). I did try and ounce and a half once with the Problend because it has vybar and can handle more FO. It didn't help. I've used a few different containers but recently I've been using 8oz glass jars with HTP73 wicks, though I've used the Premier series too. I use FO from The Flaming Candle a lot, but also sometimes from Peak or Save on Scents. I use the extra wax after pouring candles to make tarts that usually work a lot better, smell wise, than the candles themselves. If you have any advice, I'd really appreciate it! I don't know what to try next and I'm frustrated! Thanks so much!!
