Candles burn because the molten wax is drawn into the wick.
If the size of the wick is the right one for the candle, it will give an even, smoke-free flame, and an even-melting candle is the result.
A candle works similarly to a paraffin heater or a lamp. If the wick in it is too small, there will be too much molten wax-and, the chances are, the candle will be flooded. On the other hand, if the wick is too large there will be a shortage of wax and the candle will smoke.
Wicks are sized in strands, which are plaited together in three bundles. For example, 3/6's means three bundles of six strands each. |
