takes science and patience to some extent, I know I tried the advance and I know I had issues with it but cant remember what, just remember I didnt like it. Stick with one jar and one scent with one wick and test all the way down, taking notes along the way. then judge from there if you need to go up or down with your wick or up or down with the scent%. Its not easy with any wax you have to get the wax and the wick and the scent to all match the jar size also, that is where the patience and testing comes in at. Good luck and have fun
