Hello, I've looked all through the candle threads and couldn't find an answer to my question: How long is the scent supposed to last in a soy wax melt? I have made two batches so far. The first batch is made with Ecosoya Pillar wax and the scent (WSP's black raspberry vanilla) lasted for about 4 hours. After reading through the threads on wax melts, I blended the ecosoya with Golden Brands 464 soy wax (50/50 ratio) and used the fragrance at 10% (WSP's Alpine Frost). The scent lasted longer, about for 6 hours. Is this about how long the scent should last in soy wax melts? Thank you in advance for any help you can give me.
