What You'll Learn
Burn time
The burn time of an 18 oz candle can vary depending on several factors. Firstly, the type of wax used in the candle can affect burn time. Different types of wax have different densities, which can impact how long the candle burns. The size and type of wick can also play a role in burn time. Larger wicks burn through wax faster, and certain materials, such as lead and zinc, may influence how efficiently a candle burns.
Additionally, environmental factors can come into play. For example, a candle placed in a drafty area may burn quicker. The temperature of the glass container can also be a factor—if the glass gets too hot, it can affect the overall burn time. Candles should be used in a well-ventilated area to ensure proper air circulation and optimal burn conditions.
To maximise the burn time of an 18 oz candle, it is recommended to allow the candle to burn long enough during its initial use for the wax pool to reach the edge. This helps prevent "tunneling," where the candle begins to tunnel down into the wax instead of melting evenly across the surface. Proper wick maintenance, such as trimming the wick to about 1/4 inch before lighting, can also contribute to a longer burn time.
On average, an 18 oz candle is estimated to have a burn time between 110 and 115 hours. However, this can vary depending on the specific candle's characteristics and the environmental conditions in which it is burned. To determine the precise burn time for a particular candle, one can conduct a test burn, burning the candle for a set duration and measuring the amount of wax burned. This process can be repeated until consistent results are achieved.

Wax weight
The weight of an 18 oz candle refers to the total weight of the candle, including the wax, wick, and container. In the United States, it is a requirement to list the net weight of a candle in both standard ounces (oz) and metric grams (g). The net weight specifically refers to the weight of the wax and wick, excluding the container or jar.
For example, if a candle in a jar weighs 18 oz in total, the net weight of the wax and wick may be around 16 oz. The weight of the wax can be measured by weighing the container before and after adding the wax. It is important to note that the weight of the wax may vary depending on the density of the wax and the size of the container.
In general, the weight of a candle is a crucial factor in determining its burn time and lifespan. A larger candle with more wax will typically have a longer burn time compared to a smaller candle. Additionally, the type of wax used, such as soy wax or a blend of natural and synthetic ingredients, can also impact the burn time and fragrance of the candle.
When creating or selling candles, it is important to accurately label the weight of the product. In the US, the label should include both the total weight of the candle and the net weight of the wax and wick, excluding the container. This ensures that consumers have accurate information about the product they are purchasing.

Container size
When it comes to container size, the general rule is that the volume of the container is larger than the weight of the wax inside. This is because the weight listed on a candle label typically refers to the net weight of the candle, which is the weight of the wax and wick only, excluding the container.
For example, an 18 oz candle will likely be sold in a container with a larger volume, such as a jar or tin, that can hold 18 oz of wax. The final weight of the candle, including the container, may be heavier than 18 oz. However, the weight listed on the label specifically refers to the weight of the wax inside.
In the United States, it is a requirement to list the net weight of the candle in both standard ounces (oz) and metric grams (g). This means that if a candle is labelled as 18 oz, it refers to the weight of the wax and wick, excluding the container.
It's important to note that the density of wax affects how much can fit in a container. Wax typically has a density of around 85%-90% of the density of water. Therefore, a container that holds 18 oz by volume should be able to hold at least 15.3 oz to 16.2 oz of wax, depending on factors such as the lid used and the amount of headspace left.
The size of the container is crucial in candle making, as it determines the amount of wax that can be used and, consequently, the burn time of the candle. A larger container will hold more wax, resulting in a longer-lasting candle. Additionally, the shape and width of the container can influence the size of the pool of melted wax created during burning, which can impact the overall burn time and fragrance throw of the candle.

Fragrance
When it comes to 18 oz candles, fragrance is a key consideration. The scent of a candle is one of its most important features, and getting the fragrance just right is a complex art. The fragrance load, or the percentage of fragrance oil in the candle, is crucial to the candle's performance. Too much fragrance can result in dry or lumpy wax, or even a candle that won't hold a flame.
The fragrance load for candles typically falls between 5-6%, but it can go up to 10% for certain waxes. It's important to note that the fragrance load is given as a percentage by weight, not volume, as the density of wax and fragrance oils can vary. To calculate the fragrance load, you need to know the maximum fragrance load percentage for your chosen wax, which is usually provided by the manufacturer. This percentage is then converted to a decimal and multiplied by the number of wax ounces to give the maximum ounces of fragrance oil. For example, if you have 16 ounces of wax and a 10% fragrance load, you would calculate 16 x 0.1 = 1.6 ounces of fragrance oil.
There are also online fragrance load calculators that can help determine the amount of fragrance oil needed based on the number of candles, container size, fragrance load percentage, and wax type. These tools can be useful for candle makers to ensure they are using the correct amount of fragrance oil and avoiding waste.
In the case of the 18 oz candle, the fragrance load would depend on the specific wax used and the desired scent throw. A higher fragrance load doesn't always mean a stronger scent, and testing is often required to find the perfect ratio of fragrance oil to wax. It's a delicate balance, as using too much fragrance oil can result in an unpleasant smell of burning fuel.
For example, the Sweet Grace 18 oz candle by Bridgewater Candle Company uses a special soy-blend wax to enhance the performance of its unique fragrance. This candle has an Oriental & Spice fragrance with notes of passion fruit, sparkling tea, and patchouli, creating a warm, peaceful, and pure atmosphere. The subtle and classy scent is well-balanced, avoiding any overpowering effects.

Candle care
An 18 oz candle is a large candle that can burn for a long time. To ensure that you get the most out of your 18 oz candle, there are several candle care tips you can follow.
Firstly, before lighting your candle for the first time, trim the wick to about a quarter of an inch. You can use scissors or a wick trimmer to do this carefully. For wooden wicks, trimming is especially important due to carbon buildup on the wood. Trimming the wick allows the candle to have a steadier flame and prevents excessive sooting and smoke.
When lighting your candle for the first time, let it burn for a maximum of four hours. This allows the entire upper layer of wax to melt, which is the optimal diffusion potential for the fragrance. This step will ensure a long and even burn in the future.
After blowing out the flame, recenter the wick while the wax is still liquid. Use tweezers to place it back in the middle to prevent the glass from getting too hot. To avoid tunneling, make sure to burn the candle long enough during the first burn for the wax to melt evenly.
To limit excess smoke and prevent hot wax from splattering, use a candle snuffer to put out the candle. Hold the snuffer over the flame for about five seconds. Allow the candle to cool before moving it and covering it with a lid. Keeping your candle clean will help it last longer and preserve its scent.
Finally, discontinue use of your candle when there is just a quarter of an inch of wax left in the jar. Burning a candle with too little wax can cause excessive sooting or overheating of the jar.
