I love the 464 and it's all I've used for years when making containers. I let the candles cure for 7 days but have found that if they sit around time extra to that that they will sometimes get even stronger. I have had scents that I didn't think would throw well, so I just shoved the candles in the box - light them 6 weeks later in the bathroom and SURPRISE! But kidding aside, if the FO is going to work good in the wax, it will throw within 7-14 days, sometimes sooner.
