Follow These instruction for safe candle burning.

The first time you light the candle, allow it to burn until the liquid wax covers the entire top of the candle. This breaking-in process insures that it will perform better and more evenly throughout the life of the candle. This will insure a clean and efficient burning cycle for the life of the candle.

Never leave a burning candle unattended. Keep out of reach of children  and pets.  Place burning candle on heat-resistant surface. Never move a candle while it's hot. Blow out the candle if jar becomes excessively hot.  Keep candle wicks trimmed 1/8 to 1/4 inch before each burn. If you notice a large flame during burning, blow out the candle & trim the wick before re-lighting.
