Hi, I have been making some cupcake candles using soy wax using ecosoy pillar blend for the cake part (excuse odd description) and cb-adv for the whipped part and the top does melt rather quick and sometimes floods the wick. Do I have a wicking issue? (I use Eco wicks, currently testing between a 2 or 4) I would be very greatful for some advice on which size is better. Also can anyone suggest whether to use the same wax for both parts or carry on the way I am please? I always burn them in a glass souffle dish. Thanks very much x
