When you first light your candle, allow the wax to melt all the way to the outer edges of the container. This is important so that the candle burns evenly, and does not burn a well down in the middle and allowing it to get the optimal fragrance.
Maximum Burn Times
You should not burn a candle for longer than four hours at a time. If a candle is burnt for a long period without being re-solidify, the heat gain throughout the long hours will cause a fragrance lose.
Keep the candle away from direct sunlight and store them in a cool and dark places.
Trim the wick to ¼ inch with a wick trimmer before you light it on the subsequent burns. If the wick is not trimmed, it may produce smoke and burn at a faster rate.
Do not leave candles unattended and place it away from children and pets.
Always place candles on a heat-resistant base, and set on a stable surface.
