The type of wax, the diameter of the candle, the wick's size and the matter (cotton, wood, etc), all affect the burning properties of a candle. Focusing on the wicks... usually suppliers provide WICK CHOICE GUIDES, but be aware that these guides are supplier-specific!!! I have to admit that the only way to sort this out is by testing the different wicks! This example should help you understand if you did the right choice (see picture). These candles are both made of soy wax. Left: OK Right: small pool of melted wax, WRONG
