Key Takeaways - Candles in mason jars safe

  • Choose mason jars made of heat - resistant glass that can handle the high temperatures from a candle's flame without shattering.
  • Select non-combustible and non-porous materials for your candle containers to prevent fire risks and ensure easier maintenance.
  • Always place candles in mason jars on a stable, heat - resistant surface to protect against fire hazards.
  • Keep burning candles away from any flammable objects like curtains or bedding to reduce the chance of accidental fires starting.
  • Never leave a lit candle unattended; always extinguish it before leaving the room or going to bed for home safety.


Understanding Safe Container Options for Candles in Mason Jars

When choosing containers for candles in mason jars, it's important to consider heat resistance, non-combustible and non-porous materials, and look for ASTM certification. These factors ensure the safety of your candle holders and reduce the risk of fire hazards.

Heat resistance

Mason jars must withstand the heat generated by candles without cracking or breaking. Select jars made of heat-resistant glass designed to endure temperature fluctuations. This type of glass, often thicker and tougher than regular glass, ensures that the jar doesn't shatter when exposed to the candle's flame for extended periods.

Using a mason jar that lacks appropriate heat resistance can create a fire hazard in your home. To ensure safety, avoid using thin-walled or decorative jars not intended for high temperatures.

Sturdy glass containers reduce the risk of accidents, keeping both the candle wax and flame contained if tipping over occurs. Always choose quality heat-resistant containers for peace of mind while enjoying your candles' glow.

Non-combustible and non-porous materials

When selecting a container for candles in mason jars, prioritise non-combustible and non-porous materials. These materials do not ignite or burn easily, reducing the risk of accidents.

Look for glass or ceramic containers that are specifically labelled as non-combustible to ensure maximum safety.

Using non-porous materials is equally important as they prevent the absorption of candle wax which can compromise the structural integrity of the container. Additionally, non-porous containers are easier to clean and maintain, prolonging their lifespan and ensuring safe use over time.

Look for ASTM certification

When considering the safety of using mason jars for candles, it’s important to look for ASTM certification. This certification ensures that the glass used in the jar meets specific heat resistance standards, making it a safer option for containing candles.

By choosing mason jars with ASTM certification, you can have peace of mind knowing that they have been tested and approved for their ability to withstand the heat generated by burning candles.

Tips for Safely Using Candles in Mason Jars

Place your mason jar candles on a heat-resistant surface and keep them away from flammable objects. Never leave them unattended while they are burning.

Place on heat-resistant surface

Set candles in mason jars on a heat-resistant surface to prevent the risk of fire or damage. Using a trivet, ceramic tile, or candle coaster will protect your furniture and reduce the chance of accidents.

Opt for a sturdy and level surface that can handle heat, such as stone countertops or metal trays. Always ensure there are no flammable materials nearby before lighting candles in mason jars to guarantee safety.

Keep away from flammable objects

Place candles in mason jars on a stable, heat-resistant surface away from materials that can easily catch fire. This includes curtains, bedding, and any other flammable items. Always ensure there is a clear space around the candle to prevent accidental contact with anything combustible.

When using candles in glass containers, it's vital to keep them well away from any potentially flammable objects to maintain safety within your home.

Never leave unattended

Never leave candles burning in mason jars unattended. Always extinguish the flame before leaving the room or going to sleep. This simple practice significantly reduces the risk of fire hazards and keeps your home safe.

To prevent accidents, never forget to blow out the candle before leaving it alone. This small action can make a big difference in maintaining a secure environment in your home.


In conclusion, candles in mason jars can be safe when used correctly. Always choose heat-resistant and non-combustible materials for the container. Place the jar on a heat-resistant surface and away from flammable objects to enjoy candlelight safely.

Remember never to leave a burning candle unattended.
