What You'll Learn
Plastic containers are unsafe for candles
Even if the plastic does not melt, it may still be flammable and could catch fire. Some essential oils and fragrance oils will also break down the plastic over time, even without heat being applied. Plastic containers are also more likely to leak, and this can cause a very large flame to develop in a short space of time. The container shape is also important, and a wide mouth with a narrow bottom will get hotter and hotter and may crack.
The best containers for candles are those that are heat-resistant. Jelly jars are a popular choice as they are designed to withstand high heat and hold wax well. Thick glassware is also a good option, as are ceramic bowls, treated flower pots, and well-sealed metal tins.
It is important to remember that any container can crack, so proper supervision is always necessary. Candles should always be placed on a heat-resistant surface, away from anything flammable, and never left unattended.

Plastic containers can melt when in contact with heat
When making candles, it is important to remember that the container chosen must be able to withstand the heat of the melted wax and the flame. Plastic containers can melt when in contact with heat, and this can cause a mess and even a fire hazard. Different types of plastics have different melting points, for example, Polyethylene (HDPE or LDPE) melts at 115°C to 135°C, while styrofoam only melts at 240°C. It is important to note that some plastics, like polystyrene, can start to soften at lower temperatures, around 100°C, and this can cause the plastic to collapse or warp.
When choosing a container for a candle, it is best to avoid plastic containers altogether and opt for materials that are known to be heat-resistant, such as glass, ceramic, or metal. Jelly jars, for instance, are designed to withstand high heat and hold wax reliably. Other types of glassware are also suitable, as long as they are thick enough. Ceramic bowls, properly treated flower pots, and well-sealed metal tins are also good options. These materials are less likely to crack or leak, which are common problems with plastic containers.
Even heat-resistant containers can crack, so proper supervision is crucial when burning candles. Candles should always be placed on a heat-resistant surface, away from anything flammable, and never left unattended. The shape of the container also plays a role in its heat resistance. Containers with a wide mouth and narrow bottom tend to get hotter as the candle burns and are more prone to cracking.
While some plastic containers may be marketed as safe for hot items, it is generally not recommended to use plastic containers for candles due to the risk of melting or deformation. Plastic containers are designed for specific temperature ranges, and using them outside of those ranges can be dangerous. For example, plastic containers that are safe for the dishwasher or boiling water may not be suitable for holding hot wax or a burning candle.

Properly engineered plastic containers are safe for candles
When it comes to candles, safety is paramount. The wrong container can lead to explosions or fires, so it is important to choose the right materials. While some sources advise against using plastic containers for candles, citing concerns about melting or the breakdown of the plastic over time due to essential oils and fragrance oils, others have had success with plastic containers that did not melt or burn.
Properly engineered plastic containers can be safe for candles. Plastic memorial and prayer candles, for example, are commonly sold in plastic cases in Spain and the Czech Republic without any reported problems. These candles are intended for outdoor use, and while there may be some fumes, they are considered safe.
It is important to note that not all plastics are created equal, and some plastics may be more heat-resistant than others. Heat-resistant plastics can withstand higher temperatures without melting or warping. When choosing a plastic container for a candle, it is crucial to select one specifically designed for this purpose, ensuring it is made of a heat-resistant material.
To ensure safety, it is recommended to fill the intended container with water and observe it for a few days to check for leaks. Additionally, proper supervision is essential when burning any candle. Candles should always be placed on a heat-resistant surface, away from anything flammable, and never left unattended.
By choosing the right type of plastic and following safety precautions, it is possible to safely enjoy candles in plastic containers.

Glass containers are unsafe for candles
Glass containers are not the best option for candles. Glass containers can crack or break, especially when heat is applied unevenly or concentrated in one area. The most common causes of glass breaking due to heat from a candle flame are a wick that is not centered and a flame that gets too close to the bottom. If the flame reaches the bottom of the container, too much heat may be concentrated at the base of the wick, which could cause the glass to crack.
Even ASTM-approved heat-resistant glass is not a guarantee against breaking or cracking. Glass containers can also leak, causing a fire hazard. If the melted wax leaks out of the candle, the wick will burn higher and larger than it should. This can easily get out of control if left unattended.
In addition to being resistant to fire and leaks, look for heat-resistant containers. The container needs to withstand the heat of the wax pool and flame. Jelly jars, ceramic bowls, properly treated flower pots, and well-sealed metal tins are all good options for candle containers. They are often more heat-resistant than clear glass.
When choosing a glass container for a candle, it is important to consider the shape. Containers with a wide mouth and narrow bottom will get hotter as the candle burns and may be more prone to cracking. Proper caution should be used when burning any style of candle. Place the candle on a heat-resistant surface away from anything flammable, and never leave it unattended.
