Container candles are one of the best ways to start making candles. Why? Because it is very simple in terms of how to make container candles. Some people start by buying the nicest jars and tins they can find. In contrast, others want to repurpose items such as candles in glass jars, coffee cups, tins, tea cups, or yogurt pots. Experienced candle makers like myself make candles from a combination of both in addition to candle molds.
However, you may be surprised at how many containers are not suitable for candle making. Using the wrong candle container can lead to an explosion or fire. So, it is important that you know what is safe to use for making container candles.
At first, it may be possible to choose a candle container based on your personal style or home decor. But, ultimately it comes down to whether or not it is safe to make candles. This is the starting point for candle safety issues.
This may go without saying, but avoid any container that is prone to tipping over. For example, something with an uneven bottom surface, such as a hand-thrown ceramic bowl, is probably not a good idea. Or a top-heavy object, such as a wine glass that might tip over.
Another thing to consider regarding stability is the surface on which the candle is placed to burn.

There is not much to discuss this candle-making tip, but it addresses the most common candle container issues. There is good reason to check the shape and diameter of the candle container.
Imagine a vase with a full bottom and a narrow opening at the top. This shape is perfect for flower arrangements, but the diameter at the top is too small to properly wick and burn the candle.
If the top of the container is narrower than the bottom, it is not suitable for candle making. Why? Because as the candles burn, they form a circular molten pool in the wax. As the wax burns, it goes deeper into the candle.
The diameter is too small compared to the bottom of the container and will be exposed to higher heat than is safe. Not only will you have a candle tunnel, you will also risk the candle breaking.
If you have a container with a much wider opening than the bottom, you may need multiple wicks. When you look at the candle wick size chart, you will notice that even the largest wicks can only be used for candles up to 5 inches in diameter.
I think the popularity of dough bowl candles may be somewhat misleading when it comes to choosing fire-resistant candle containers. Basically, anything that catches fire easily is not safe. Basically, the candle may burn up, or the container may absorb the wax and turn into a giant wick, which creates a huge flame.
The difference is in the sealant! When you apply a 100% waterproof sealer to a wooden bowl, clay pot, or any porous container, it becomes safe to use.
It is recommended to apply two thick coats of sealant between the two layers and dry time. However, keep in mind that no amount of sealant can make something like plastic safe to use as a candle container.
You may think that the sealant will also cover the container when it leaks, the size and speed, and you may have a mess in front of you. So, to avoid this candle problem, fill your candle-making container with water and see if it leaks. You can leave it filled for a few days to check for slow leaks.
Candle Jar and Scented Candles
When a candle container breaks, the hot wax will start to leak. We already know this can be a safety issue and a mess. However, if the crack causes the candle container to break and explode, you could get a burning wick without a container. This means the house catches fire.
That's a big problem. So, how do you know if a container won't break?
It all comes down to heat resistance.
Most things are not designed to handle the heat generated by melting candle wax. Choose heat-resistant containers such as oven-safe ceramic and glassware, cast iron, enameled camping cups, and pressure canning jars. Make sure to only purchase containers that are designed and labeled to be safe for candle making.
No matter how you look at it, burning candles should never be left unattended. We should always prevent these problems by choosing the right candle container and the right wick size.
