The last several batches of votives I've made, when I test them, they burn down very quickly in the middle of the candle. The wax collects in the container, and it then burns very well, without a lot of wax left over, but it bothers me that it burns so fast out of the center right at first. I don't remember exactly which wax I used, or the wicks - I've got that information at home and can post it later, but can't recall it off the top of my head. I know it's a soy wax made for votives, and wicks that specify that they're for votive use. Does this burning pattern mean I'm using the wrong wax for the wick, or the wrong wick for the wax? Should I keep experimenting with different combinations to see what works better? Thanks for the thoughts!
