Are All Glass Safe For Candles?

Not all glass is safe for candle making. Glass containers that are designed for canning are a bit stronger than regular glass containers. These containers are designed to withstand high temperatures, and high pressure, and are a little bit thinner and crack-resistant than regular glass containers.

You can safely use glass containers that are designed for candle making if you place them in a cool environment. You don't want to leave your candle burning unattended, so you'll want to find a spot where there is plenty of ventilation.

Candlemakers recommend placing the glass container in a cool location away from direct sunlight. You may even consider putting the glass container in a refrigerator.

You can also use glass jars that are designed to be candle holders. These jars are usually made out of clear glass and have a wide mouth opening. You can use these jars to store your favorite scented oils.

Heat Resistant Glass For Candle Making

If you plan on using your candle-making supplies outside, you'll want to make sure that you are using heat-resistant glass containers. Mason jars, jelly jars, hexagonal jars, tureens, and vases are all examples of heat-resistant containers.

You should never use regular glass containers for candle making. Regular glass is not heat resistant and can break easily at high temperatures.

Always check with your supplier to find out whether the container is suitable for candle making. If it isn't, ask them to recommend a safer alternative.

Glass Containers Safe For Candles

You can safely store candles in glass containers, including jelly jars, mason jars, and any other type of pressure canning jar. These types of glass containers are thicker, heat resistant, and unlikely to crack because they've been designed to withstand high temperatures and pressure.

Keep your candles out of direct sunlight and away from windows and doors to avoid melting wax dripping onto surfaces.

Mason Jars

Mason jars are great for storing candles. They're made out of thick glass and are very durable. You'll find them everywhere from craft stores to grocery stores. They come in various sizes and shapes, including tall, wide-mouth jars and small ones that fit inside a standard-sized jar.

Mason jars are ideal for storing candles. They are made out of thick glass, making them extremely durable. They come in various shapes and sizes, including tall, wide-mouth jars and small ones that sit inside a standard-sized jar.

Apothecary Jars

Candlemakers love apothecary jars because they are inexpensive, durable, and come in a variety of sizes. These jars are great for storing your favorite scented oils and waxes. You can also use them to store your favorite candies and chocolates.

You should never light a candle inside an apothecary jar. However, if you place the jar outside during the day, you can safely burn candles inside without any risk of fire.

Candlemakers love using apothecary jars for storage because they are inexpensive, sturdy, and come in a wide range of container sizes. You can find apothecary jars at discount stores, craft stores, and online retailers.

Hex Jars

Hex jars are safe candle containers, and they are widely available at candle supply wholesalers. These jars come in various sizes and shapes, including round, square, rectangular, oval, and heart-shaped. You'll find them in a variety of materials, including plastic, ceramic, metal, wood, and glass.

You should never light a candle inside a jar made of glass. However, if you purchase a glass container specifically for candles, then you won't have any problems using it safely.

Glass containers are great for storing beautiful candles, but they shouldn't be used for lighting them. Instead, use a giant wick holder that fits securely onto the base of the candle. This ensures that the enormous flame stays lit and burns evenly.

Unsafe Candle Containers

Let’s now take a quick glance at some different types of unsafe candlestick containers.

Glass Vase

Candles are beautiful, but they can be dangerous if you don't handle them properly. Glass vases are great for storing candles, but they weren't designed to hold hot wax. You may think that you can place a blue spruce candle in a glass container, but it won't last long.

You'll find that most glass containers are made of tempered glass. Tempered glass is heat treated to strengthen its structure. However, it still isn't strong enough to withstand high temperatures.

As soon as the temperature reaches 400 degrees Fahrenheit, the glass begins to break down. Once the glass breaks, the flame can easily reach the bottom of the container where it can cause serious burns.

Wine Glass

Candle glass comes in all shapes and sizes, including wine glasses. I prefer not to risk putting a candle inside a wine glass. Wine glasses are so incredibly thin that they greatly increase the chances of the glass breaking if there is a large enough wick and flame.

Drinking Glass

A drinking glass isn't necessarily the best container for a floating candle. You'll find that the glass tends to break under the heat of the candle flame. Instead, try using a wineglass or a clear vase. These containers won't break under the heat of a burning candle, and they provide a nice decorative touch.

You can also add a little bit of color to your floating candle by placing it inside a glass bowl. Just remember to keep the candle away from any sharp edges. Otherwise, you risk cutting yourself.

Recycling Old Candle Containers

Glass candle jars can be recycled, but not all of them are made of lead-free glass. Some glass candle vessels may still contain small amounts of lead, which can leach into the wax inside the jar. You should never pour hot wax down the drain, but rather dispose of it properly.

Scrape out the remaining wax with a butter knife and warm the jar in a saucepan with enough water to cover the bottom of the jar. Place the jar with recyclables as you normally would. Don't forget to recycle any empty glass bottles that were used to store the melted wax.

Can You Repurpose Old Candle Containers

Repurposing old coffee bean candle containers creates many storages and organizing opportunities for your home. You can use them to hold matches, paper clips, a vase for fresh flowers, planting succulents, and a candy dish!

You can find lots of creative uses for old candle containers. Just remember to keep them clean and dry after using them. Don't leave them out in direct sunlight or near heat sources. And if you plan to recycle them, make sure to wash them thoroughly before reusing them.

Pouring Candle Wax In To Glass

Candles are wonderful gifts for any occasion. However, if you've ever tried to pour hot wax into a glass container, you'll know that it's no simple task. You might end up burning yourself, or worse, breaking the glass.

To avoid these problems, you should only pour the wax into glass containers once it has reached its proper temperature. This means that you must wait until the wax reaches 135 degrees Fahrenheit before you begin pouring. Once you reach this temperature, you can safely pour the wax into the glass containers.

You can use a blow dryer to quickly warm the glass containers. Simply blow directly down onto the surface of the glass container until it reaches 135 degrees Fahrenheit. Then, start pouring the wax into each glass container.

What Happens When You Put A Candle In A Jar?

Mason jars are great containers for candles. They keep the wax at bay and prevent it from dripping onto anything else. However, if you leave a candle burning in a mason jar, there is a risk that the wax could drip down onto whatever is below it.

To avoid this problem, place a piece of paper towel underneath the bottom of the jar. Then, light the candle and let it burn until the wick goes out. Once the wick stops smoking, remove the coffee cake candle from the jar and dispose of the used paper towel.

You can also buy special candle holders that fit perfectly inside a mason jar. These holders are made specifically for holding candles safely inside mason jars.

Safety Tips

These are some helpful hints for making the best use of your candles and ensuring that they can deal with all safety issues.

Do Not Leave A Candle Unattended

Candles are wonderful, but they can be dangerous if not used properly. Never leave a glass container candle unsupervised. If it does happen to pop and start dripping wax while you are away, you could return to a disaster. You may think that you'll only be gone for a minute, but accidents happen quickly.

Do Not Place It On An Unstable Surface

You should never place a glass candle holder on an unstable surface. Glass is very fragile and if placed on an unstable surface, there is a high risk that it may break. You should only place a glass candle holder where it won't move at all.

For example, if you were placing a glass candle holder on a table, you wouldn't want it to move at all. However, if you were placing it on a countertop, you might want it to move slightly.

Trim The Wick

Double-wick candles are great for adding ambiance to any room, but if you leave the wicks untrimmed, they can burn down quickly and cause damage to your house. You should trim the wicks every month or two to prevent fire hazards.

Keep the wicks trimmed to the proper length. If the flame leans over, it can get too big and burn through the container. This can lead to cracks in the container and cause it to break.

Keep It Away From Water

You never want to keep your fire-safe candle containers near any source of moisture. Even if there isn't any direct contact between the candle container and the hot water, the heat from the gel candle can cause condensation inside the container.

As soon as the container starts to cool down, the condensation turns into steam, which expands rapidly and causes the container to burst open.

Use A Heat Resistant Surface

If you place a multi-wick candle on a heat-resistant surface, such as ceramic containers, marble, granite, stainless steel, or glass, you'll prevent the candle flame from melting the surface. You may still notice a slight discoloration, but it won't affect the appearance of the surface.

A heat-resistant surface is ideal for placing a candle on a table or countertop. You can also use a heat-resistant surface to display a candle in a vase or jar. Just remember to remove the candle after dinner or whenever the candle goes out.


You may want to start off with glass jars since they are easier to handle and less expensive than other types of glassware. However, if you decide to try glassware later, you might want to consider thicker glassware, such as mason jars, since they are safer for burning candles.

Smell is one of the human senses which can flow through the whole body. I am the Founder of where we talk all about scented candles. Known as Candace the Candle Girl, I know pretty much all there is to know about scented candles.
