Is All Glass Safe for Candles?

There are some types of glass that should not be used for creating candles. Glass that is suitable to be used in the production of candles ought to be dense, polished, and temperature resistant. Because of this, using jars like jelly jars, mason jars, and other kinds of jars used for pressure preserving are suitable for the production of containers for candles. Containers made of glass are quite common in the candle-making industry, as they should be. Soy wax, which has a low melting temperature, is used to make the overwhelming bulk of candles produced nowadays. 

Are Glass Containers for Candles Safe?

Glass can shatter or fracture, and it is much more likely to do that if the temperature that is supplied to it is delivered unevenly or is focused on one region in particular. Glass that is resilient to high temperature can be manufactured to reduce the likelihood of the glass shattering or fracturing when exposed to high temperatures. However, even glass that has been certified by the American Society for Testing and Materials (ASTM) does not come with an assurance that it will not shatter or split.

In lighting candles in containers, as with any other type of candle, the appropriate amount of precaution must be applied. Put the candle in a holder that can withstand the temperature, and you won’t have to worry about damaging the area it’s resting on. Hold the candle at a safe distance from anything that might catch fire. Be certain that the wick remains in the middle of the candle and that it is extinguished when the wax level goes too near to the base of the glass container. 

What are the Glass Containers Suited for Candles?

Jars including jelly jars, mason jars, or any other form of canning container are examples of acceptable glass containers for candles. This is due to the fact that they were meant to be utilized in environments with high pressure and temperature, which resulted in them being strong, resistant to high temperatures, and difficult to shatter.

Apothecary Jars

Candles can be stored in apothecary jars without any risk, making them among the most common types of jars sold by distributors of candle supplies. In addition, several of the most well-known candle manufacturers operating in the world today make use of them in their products.

Vibe Jars

Vibe jars are suitable for the containment of candles. In addition, they are an outstanding product for artistic and aesthetic candles due to the fact that their structure is one of a kind and draws attention. Distributors of candle supplies also commonly stock vibe jars in their inventories.

Tureen Jars

Jars made of tureen are suitable for use with candles. Given the fact that they are both short and stubby, they are frequently used as a component in the production of candles that include more than one wick. Because of this, they are perfect for making candles with multiple wicks.

Mason Jars

Candles can be used in mason jars without any risk. Due to the fact that Mason jars were intended for use in the process of canning, it was necessary for them to be able to withstand high temperatures and also compression. This would work wonderfully as a receptacle for a candle.

What are the Glass Containers Unsafe for Candles?

Not all glass could be used to light a candle. Candles must be used in glass that would be meant to resist extreme temps, such as canning or candle-holder glassware, in order to keep them from catching fire.

Drinking Glass

You should never put a candle in a cup of coffee. Because it is made of thin glass, it is prone to breaking when exposed to the extreme heat of a candle. Nevertheless, a hovering candle in a champagne glass is a smart alternative. Even though a drinking glass may not be the most attractive vessel for a hovering candle, it’s the only option if you really want to utilize the glass whatsoever. If you cut a rose long enough so that the blossom is towards the top of the glass and fill with water, you may make a vase like this at home. This is where you should set your drifting tealight if you’d like it to look its best.


Do not risk breaking the vase by placing a candle inside it. Despite the fact that one could use a candle, these also weren’t intended to withstand the high heat produced by a candle. Do not attempt unless you’re already going to be making a kind of hovering candle.

Wine Glass

Do not allow a candle to set inside of a glass of wine. If the wick, as well as the light, are just too large, there is a considerable rise in the probability that perhaps the glass may shatter due to the fragility of the material. Nevertheless, if you want a hovering candle decoration, it is a really fantastic alternative to consider. Having that said, the internet has a wealth of samples of candles made from wine glasses, but personally, We like to come down on the side of safety. It offers me the comfort of knowing that we do not have a wine or champagne glass filled with melted candle wax that has the potential to backfire at any moment.


Never place candles in ceramic or clay containers of any kind. Because the face is permeable, this could absorb wax, which may then cause this to become combustible. We like to emphasize that you must never use some kind of combustible material for candles. For example, We’ve seen people use wooden receptacles on Pinterest, which is a poor idea. Use an only smooth glass that has been specifically developed to withstand temperature and pressure. Even if the glass is fragile and therefore not built to withstand high temperatures or compression, it is possible to still utilize it to make a floating candle.

Is it Safe to Reuse Old Candle Containers?

Consider reusing the containers that hold candles for other purposes, such as a chocolate bowl, a planter for roses, a vase to grow cactus, or to keep safety pins, keys, or chopsticks. Candle jars offer a wide variety of alternatives for storage and management.

What Is the Common Cause of Breaking Candle Glass?

When the high temperature is given to glass in an inconsistent manner, it can cause the glass to shatter or fracture. Once one section of the jar starts to become significantly warmer than that of the remainder of the jar, this produces the optimum environment for a fracture to occur. The hot spot swells, putting strain on the glass container because of the reaction.

The candle jar is subjected to tension, which ultimately results in breaks. When using a candle, it is possible for the wick to become off-center and for all of the wax to dissolve at a certain point during the process. In the event that this occurs, blow out the flame, and move the wick so that it is centered again when the candle cools down. Because of this, a break might be avoided.

Is it Possible for the Candle Glass to Explode?

Whenever glass gets too hot, pressure builds up inside the material, which might eventually lead to the object exploding. When you let a candle blaze for an excessive amount of time, the fire will get frighteningly close to the container’s side or bottom. Because of this, there is a possibility that the candle will blow up. As was just discussed, all of the increased temperatures are absorbed by the glass, which then becomes stressed as a result of the difference in temperature.

If the wick is supposed to burn straight down to the base of the container, at some level it will be more beneficial to just dispose of the residual wax inside the garbage than it would be to continue letting the wick remain burning. If there is no wax in the bottom of the glass container, then the heat will have nowhere else to go but up further into the glass jar itself. Because of this, there is the possibility of a break.
