The short answer is yes, candles in glass jars are generally safe to use. However, there are a few things to keep in mind to ensure their safety. First, make sure the glass jar is thick and sturdy enough to withstand the heat of the candle. Thin or flimsy glass can crack or shatter, causing a fire hazard. It is also important to keep the wick trimmed to ¼ inch to prevent the flame from getting too large and potentially causing the glass to overheat.

Choosing the Right Candle

When purchasing a glass jar candle, it is important to look for certain safety features. Make sure the candle has a warning label that includes the type of wax used, the burn time, and any safety precautions. It is also recommended to choose candles made with natural waxes, such as soy or beeswax, as they tend to burn cleaner and produce less soot. Avoid candles with metal wicks, as they can release harmful chemicals when burned.

Proper Placement

Where you place your glass jar candle is also important for safety. Keep candles away from flammable materials, such as curtains or paper, and make sure they are placed on a stable surface. Avoid placing candles in high traffic areas where they can easily be knocked over. It is also recommended to keep candles at least 3 inches apart from each other to prevent overheating.

Extinguishing the Flame

When it comes time to extinguish your candle, it is important to do so safely. Never blow out a candle, as this can cause hot wax to splatter and potentially start a fire. Instead, use a candle snuffer or dip the wick into the melted wax and then straighten it back up. This will prevent the wick from smoking and make it easier to relight the candle next time.

Alternatives to Glass Jar Candles

If you are still concerned about the safety of glass jar candles, there are alternatives you can try. Look for candles in metal tins or ceramic containers, which tend to be sturdier and less likely to overheat. You can also opt for flameless candles, which use LED lights to mimic the look of a real candle without the risk of fire.


In conclusion, candles in glass jars can be a safe and beautiful addition to your home, as long as proper precautions are taken. Remember to choose the right candle, place it in a safe location, and extinguish it properly. By following these tips, you can enjoy the warm glow and pleasant scents of glass jar candles without worry.
