Well, the second (and only) one I used a paraffin soy mixture, KY perfect blend. It said to heat to 175 and pour at 155. So, I heated to 175, added fo and dye, mixed and poured at 155. Within a couple of hours it had already begin to sink. So I then heated this mixture up a second time thinking it was the wick so I took the wick out and started again. I reheated it, however it was heated with the fo and color. Don't know if that makes a difference being that it turned out the same the first time. Help
