Hi, Well, I finally got the perfect wick with the right melt pool, I am using gb 415 with usa and I used the htp 93's in a 16oz. elevation jar, but now the wicks are leaving a black sooty stuff on the top of my wax!!!!!!!!! Was wondering if anyone had any other suggestion of which wick to try, am going to all soy, and just need some direction please. Also have tried peaks cotton core and they do the same thing. Any suggewstions would be greatly appreciated!!! Valerie
