Thank you for your reply, I use 1 to 1 1/2 oz fragrance per lb of wax. I use Just Scents, Bittercreek, Natures garden, Indiana Candle Co. I am just stumped and frustrated, My JS 50/50 WOrks great in my containers, and my pillar wax I love too. I thought tarts were suppose to be easy!! ugh! Thanks again.
