The first time you light your candle allow it to burn long enough to create a melt pool of wax across the whole diameter of the jar.  This will prevent tunnelling of your candle wax and allow an even burn.

Never leave a burning candle unattended.

Avoid drafty areas, near an open window or fan.

Keep candle out of reach of children and pets.

Be sure the candle if kept on a heat resistant surface.

Very important to trim your wicks to 7mm before every burn this will eliminate black soot and keep the jar at the correct temperature. If the flame become too high or flickers during burning extinguish immediately and allow to cool then trim the wicks.

If the glass becomes black while burning, extinguish, allow to cool clean with a damp, not wet paper towel or cloth.

Do not burn the candle if the glass if chipped or cracked.

Always leave 1cm (10mm) of wax in the bottom of the candle.

Never move a burning candle when the wax is liquid.

Never use a knife or sharp objects to remove wax drippings. This may scratch, weaken and cause the glass to break.

Extinguish your candle with a candle snuffer this is the safest way to prevents hot wax splatters.
