Please burn your candle at least one hour at a time until the wax pool reaches the edge of the glass. This will avoid the wax forming into a funnel. Your candle will burn more even and last longer. Please do not burn your candle longer than three hours at a time. Place candles on a heat resistant surface. Keep away from flammable material and out of drafts. Make sure burning candles are out of reach of children and pets. Be aware that the glass gets hot when candle is lit. Never leave a burning candle unattended. Always trim the wick to 5 mm before ligthing the candle.
