When lighting a soy candle for the first time, allow the wax to melt all the way to the sides of the container. Depending on the container size, this should take around 1-4 hours. Failure to do this will often cause "tunneling" which will limit the life of your new soy candle. Soy wax does not burn as hot as paraffin wax, so soy wax candles require a thicker wick, which does not burn 100% and needs to be trimmed regularly. Trim your wick to about 1/4" before you re-light your candle. This will ensure a long lasting candle, minimize soot and remove any mushrooming of carbon on the end of the wick. Extinguish your candle by placing your lid back on. This will stop the wick smoking and will help with re-lighting the next time. Please remember the candles are hand poured, every candle will be a little different. When using completely natural soy wax, sometimes the top of your candle may also appear slightly uneven.
