Rustik Lys's TIPS for burning candles

Before you light the candle

Provide a non-flammable, suitable and stable candle holder.
Make sure candles are firm and straight. A candle that is tilted always drips and smokes.
The wick must be kept clean and short at all times (no longer than 1 cm). If necessary, cut the wick before lighting the candle and make sure the wick is upright. If the candle produces soot or a large flame, a piece of the wick must be cut.

Placing the candle

Keep a distance of at least 10 cm between burning candles. Candles that are too close together heat each other, which can cause the candle to drip.
Never place a burning candle near children, pets or animals.
Do not place burning candles in a draft. A candle on the draft is always dripping and smoking.
Never place a candle near curtains or other flammable objects. After all, it is an open fire.
Do not burn candles near other heat sources, such as TV, radiator, fireplace, etc. The candle may drip.
Never place candles in direct sunlight. The high temperature can cause the candle to melt and discolour.

When the candle burns

Do not let bulb and pillar candles burn for longer than 3-4 hours at a time.
Candles with a diameter of 10 cm or more should remain lit the first time until the candle has melted about 1 cm from the outer rim. This is to prevent 'tunnels' from forming, after which the candle can never burn properly again.
Do not move burning candles!
Do not leave burning candles unattended.
Do not put a burnt match or other materials into the wax. This can cause a second flame, causing the candle to burn incorrectly and to drip, smoke or even worse, explode.
Candles need enough oxygen to burn properly and must be able to dissipate their heat, so be careful when burning candles in lanterns.
If the candle burns deeply, cut a piece off the edge.

When the candle is running low

Do not allow candles to burn more than 2 cm from the candleholder.
Extinguish candles with a candle extinguisher. Never extinguish a candle with water.
Outdoor candles are sensitive to moisture in combination with frost. This can make them burst.
