I used a 50/50 blend of igi 4627 and 4687 in a 16 ounce Kerr Jar double wick using 2 lx 14 and white tea fragrance. The throw was amazing the melt pool was exactly a half inch. This fragrance while very light stood out. I thought I lost it when I added to wax stirred 2 minutes and nothing. Was actually very disappointed until I did the burn test. This smell is not for me. It's smells a bit like older lady perfume. When I think of spa fragrances I think of clean and crisp. The black sea candle science does is a perfect spa smell (to me). It's one of those things you just gotta try for yourself. To me it's very perfumey. I don't believe I would have had the same throw using one wick as it is a lighter smell. I think I rather smell this in a soap instead of a candle. But that's just me. I will not order this one again. It's not one of those power house smells. I would highly recommend ordering the sample on this one.
