To prevent a candle from dripping, make sure that the wick is trimmed to about ¼ inch before lighting it. You can also use a candle snuffer to extinguish the flame, as this can help prevent excess wax from melting and dripping down the sides of the candle.

It is best to store candles in a cool, dry place, away from direct sunlight or heat sources. This will help prevent the wax from melting

It is generally recommended to burn a candle for no more than 4 hours at a time. This will help prevent the candle from overheating

It is generally not recommended to reuse a candle jar, as the wax residue and soot from previous burnings can be difficult to remove. However, if you do want to reuse the jar, make sure to clean it thoroughly with hot, soapy water and a scouring pad to remove any remaining wax and soot.
