A burning candle is a naked flame !

The candle must be treated carefully and constantly controlled:

Never leave a burning candle unattended
Don’t burn candles too close together. Minimum 10 cm distance in necessary between each candle.
If you light a candle the wick should be straight.
You should avoid drafts in your room during the burning of the candle
If the flame of the burning candle get’s to high please shorten the wick in order to avoid the sooting of the candle
Pieces of matches, of the wick or other things should not be left in the liquid wax on the top of the candle
Candles should burn as long that the wax on the top of the candle is melted totally. Otherwise the candle may get a thick edge.
If the wick lays to much to one side please move the wick up to right position
In order to avoid the afterglow of the wick, please dip the wick into the liquid wax and put up the wick again.
