Many novice candle makers often kick off their crafting experience by creating container candles. This choice is ideal for beginners due to its simplicity and ease of execution. Nonetheless, newcomers might encounter challenges when it comes to choosing a suitable container that not only enhances the candle's aesthetic appeal but can also withstand the heat generated during burning. Opting for an inappropriate jar could lead to dangerous outcomes, such as broken glass, spilled wax, or even a fire hazard.
Here we will look at how to select the best vessel for your container candles.
Heat Resistance
It's important to choose a container for your candles that can handle heat. If you opt for glass jars, ensure they are crafted from tempered glass, as these are designed to endure high temperatures. Canning jars are particularly suitable due to their durability against heat. Avoid using thin glass items like wine glasses, as they are prone to breaking. Alternatively, you might consider using oven-safe ceramics, cast iron, or metal tins, as these materials are also resistant to the heat generated by candles.
Fireproof
It's likely you've noticed the rising trend of utilizing dough bowls and various wooden containers for candles. However, the widespread appeal of these candle vessels might create confusion among novice candle makers regarding what constitutes a truly fire-safe container. If left untreated, these wooden pieces can ignite, posing significant hazards. They can soak up wax, potentially turning into a large wick made of wood. Opting for a flammable container carries considerable risk.
Should you choose to utilize a dough bowl or any wooden container as your candle holder, it is essential to apply a substantial layer of 100% waterproof sealant beforehand. Avoid using plastic containers for candles at all costs; no matter how thickly you apply sealant, the heat from the candle will still cause the plastic to melt.
Candle vessels crafted from materials such as cement, terracotta, and clay are quite favored. However, in their untreated state, these materials are highly porous and can soak up melted wax, posing a fire hazard and safety risk. To safely use these containers for candle making, it’s essential to apply a substantial layer of sealant beforehand.
Shape matters
Though it may be appealing to opt for a uniquely shaped container, it's crucial to consider potential issues when it comes time to choose a wick. Remember that a wick generates a circular melt pool that retains the same diameter from the initial burn through to the final one.
For instance, selecting a vessel that is narrower at the top and broader at the base could lead to wicking challenges. A wick designed to create the appropriate diameter at the top would likely produce a tunnel effect toward the wider bottom. Conversely, if you were to use a wick suitable for the wider base, it could overheat the narrower top, risking the possibility of the glass breaking.
Opting for a cylindrical shape with vertical or slightly tapered sides is a far more effective choice.
Additionally, it's important to ensure that your container has a stable base. A vessel with an uneven bottom or one that features a pedestal design may be prone to tipping over easily.
Other considerations for glass containers
When choosing the perfect glass jar to hold your candles, there are some other factors you should consider:
It's best not to use recycled glass because it doesn't perform as well in heat.
It is not recommended to use glass vessels with bubbles. These bubbles may look nice, but the glass in those areas is thinner and more susceptible to heat.
Check your glass for cracks and weak seams. All of this could lead to a jar breaking and creating a mess.
What are the best containers for candles?
While glass containers are among the most widely used vessels for candles today, it's important to note that not all glass is suitable for this purpose. For a glass container to be appropriate for candle making, it must be thick, smooth, and capable of withstanding high temperatures.
Mason jars are an excellent choice for candle vessels because they are specifically designed for pressure canning, allowing them to endure temperatures of up to 250°F. Their nonporous nature, combined with their thickness and smooth surface, prevents cracking during use.
In fact, any glass jar that shares these characteristics can be a viable option for crafting candles. Below is a list of jars that are recognized as safe for this activity.
On the other hand, it is advisable to steer clear of drinking glasses, wine glasses, glass vases, and other fragile decorative glass items.
Candle tins are an excellent option for those interested in making candles. They come in a variety of stylish designs and attractive colors, making them visually appealing. Additionally, labeling them is straightforward, whether on the top, bottom, or side.
A significant advantage for those crafting candles is that metal containers obscure the wax inside, unlike glass jars. This quality makes tins particularly suitable for novice candle makers, as they effectively conceal flaws such as frosting, uneven surfaces, and "wet spots."
However, it is essential to exercise caution with these tins since they can retain heat. It’s advisable to include a warning label on your candles to inform users not to touch them while hot, as this could lead to burns.
Ceramic Candle Containers
Ceramics are an excellent choice for candle-making! They offer durability, withstand heat, and many are pre-sealed. Essentially, if a ceramic vessel is labeled as safe for microwaves and dishware, you’re all set!
When using a ceramic mug or container that has been used before, be sure to check for any cracks and ensure it's in good shape. If you discover a ceramic piece you adore that isn’t sealed, simply apply two layers of sealer to make it suitable for candles.
Concrete Candle Containers
In recent times, concrete has gained significant popularity. Its distinct industrial aesthetic, combined with its durability and leak-proof properties, makes it an excellent choice for candle holders. Known for its heat and fire resistance, concrete provides a safe environment for candles. However, due to its porous nature, it is advisable to seal the concrete prior to pouring in wax.
Conclusion
When selecting a candle container, you’ll find a wide variety of choices available; however, not all of them are safe for use. It's important to conduct thorough research prior to purchasing multiple containers. Make sure to test each one in a secure environment to observe how they respond to heat.
