Why use Zinc core wicks ?
Again, due to three very important factors: One is, wire core wicks burn at the proper temperature for ‘glass/ceramic type container’ candles, and this is a necessity for CONTAINER JAR CANDLES, for safety precaution. The second reason – CONTAINER CANDLES NEED and are designed to have A LARGER ‘MELT POOL’ for scent throw, but without the metal core to hold up the wick in this larger melt pool of wax, it could essentially ‘sag’ and your candle would snuff itself out. It would ‘defeat’ the purpose of having a container candle. The third reason – with any ‘potential’ sagging or leaning of wicks against your ‘container, THAT becomes a hazard as your ‘container candle’ can crack due to the extreme heat from the flame leaning against the wall of the container. That is why you are instructed to always keep your wicks straight and centered, especially if they are bent when you extinquished your candle and to stop burning your candle with 1/2 to 1 inch of unused wax in the bottom of your jar.
