How To Use In 4 Easy Steps –  Make sure that your container or vase is heat-resistant. Pour in the desired amount of candle sand.2- Insert the wick into the container, allowing it to protrude about 1 cm above the surface. This will ensure that the candle burns calmly and does not produce soot. For a single wick, ensure a diameter space of 7 cm around it; for multiple wicks, maintain a distance of at least 7 cm between them. 3- To light the candle, use a long lighter or matches. Remember to be careful. 4- Safely extinguish the candle by blowing it out or using a candle snuffer. Allow the melted wax pool to harden. To reuse the unburned wick, flip it along with the hardened wax upside down and light it. If the wick has burned down, replace it with a new one to make it look brand new.
