You can find some interesting information about palm wax at CandleScience.
Candles made from palm oil have a pretty frost or feather effect and each candle is unique because they all crystallize into different patterns. No additives are necessary, one pour is usually enough and palm wax has an excellent scent throw.
Apparently, palm wax can hold twice as much scent and you can use it for pillars, containers or votives. Since I haven’t tried it yet I’m taking people’s word for it. I will let you know how it goes when I do try making candles from palm wax.
