When lighting the candle please allow the wax to melt all the way to the sides of the container. This should take 1-3 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.
Aim to 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.
Please remember the candles are hand poured, not massed produced - and although every effort is made to ensure consistency, every candle will be a little different.
When using completely natural soy wax, sometimes you may notice darker patches or "wet" spots in your candles. This is not a fault, simply a small blemish where the wax has not adhered to the glass 100%. The top of your candle may also appear slightly uneven, this is also a sign of natural soy wax being hand poured.
Fragrance should last 20+ hours per cube, but due to the varying power of melters and how subjective smell is that number may vary greatly.
