What You'll Learn
Candle specifications: wax, fragrance, dye, wick, etc
Candle testing sheets are an important resource for candle makers to keep track of every candle they make and ensure their candles are of high quality. They are also useful for recording important information about the candle-making process, such as the materials used and the quantities and temperatures employed.
Candle specifications are a crucial part of the candle burn test document. This section covers the materials used to make the candle, including the type of wax, fragrance oil, dye, and wick. It also includes the quantity of each material used, in grams, and the temperatures at which the candle maker worked, including the temperature at which the wax was melted and the fragrance oil and dye were added, and the temperature at which the mixture was poured. Any notes on the process, such as whether the candle set lumpy or had a sinkhole, can also be included in this section.
The type of wax used in candle making can vary, with some common types being paraffin, soy, coconut, and beeswax. The choice of wax may influence the choice of wick, as certain types of wax may require a larger wick size. For example, higher-viscosity waxes such as single-pour paraffin wax, soy wax, and beeswax may require a wick several sizes larger than recommended.
Fragrance is another important specification to include on a candle testing sheet. This should include the type and amount of fragrance oil used, as well as the strength of the fragrance when the candle is lit and unlit ("hot throw" and "cold throw"). It is also useful to note how far away the fragrance can be smelled when the candle is lit.
The type and amount of dye used should also be specified, as this can affect the burning characteristics of the candle. Too much dye can clog the wick, leading to a smaller flame and increased soot. Therefore, it is important to stick to the recommended amount of dye and to ensure that it is fully melted and mixed before pouring the wax into molds or containers.
Finally, the type and size of the wick should be recorded on the candle testing sheet. The correct wick selection will ensure a candle achieves a full melt pool, throws fragrance well, and does not produce excess soot. Wick size can depend on various factors, including wax type, fragrance and dye used, container size and shape, and any additional additives.

Burn test factors: melt pool diameter, tunnelling, soot residue, etc
Burn testing is the process of evaluating finished candles for performance from the first to the last burn. The goal is to ensure that your candle burns at a normal rate, doesn't produce an abnormal amount of soot, and is safe for the end user. The candle burn test is made up of many different tests that ensure the candle is burning correctly, safely, and smells pleasant.
One of the key factors to consider is the melt pool diameter. This refers to the diameter of the wax pool that forms around the wick as the candle burns. An ideal melt pool diameter is one that extends evenly across the entire surface of the candle, ensuring complete and efficient burning without leaving excess wax on the sides.
Another important factor to look out for is tunnelling. Tunnelling occurs when a candle burns down the centre, creating a tunnel and leaving excess wax along the sides. This can be caused by an inadequate wick size or type, improper burning conditions, or poor-quality wax. To avoid tunnelling, ensure you are using the correct wick size and type for your candle diameter and that your burning environment is draft-free and at an appropriate temperature.
Soot residue is also an important consideration in burn testing. Soot is the black or dark residue that can form on the glass or container of a candle as it burns. While some soot is normal, especially with certain types of wax like paraffin wax, excessive soot can indicate an issue with the wick, wax, or burning conditions. It is important to evaluate the amount and type of soot residue to ensure the candle is burning cleanly and safely.
Other burn test factors include evaluating the fragrance of the candle, both when it is lit ("hot throw") and when it is in its solid form ("cold throw"). This involves marking the strength of the fragrance on a scale and determining how far away it can be smelled. Additionally, the performance of the wick should be assessed, including whether it produces smoke, if there is mushrooming, or if it fails to stay lit.

Hot and cold throw: how the candle smells when lit and unlit
When testing a candle, it's important to evaluate its hot and cold throw—how the candle smells when lit and unlit, respectively. Here are some detailed insights to guide your evaluation:
Cold Throw:
The cold throw of a candle refers to its fragrance or aroma when unlit. It gives you a preview of the scent, but it can be subtle and deceptive. Cold throw is important as it attracts customers and encourages them to make a purchase. Citrus and lighter floral scents, such as rose, honeysuckle, and lemon verbena, typically have a stronger cold throw. When evaluating a candle's cold throw, pay attention to the following:
- Fragrance: Describe the scent and its strength before the candle is burned for the first time.
- Room size: Consider the size of the room where you'll be placing the candle. A stronger cold throw may be preferable for larger rooms to create a subtle ambiance.
- Personal preference: Decide if you prefer a candle that subtly enhances the space without overwhelming it. If so, look for a candle with a stronger cold throw and a milder hot throw.
Hot Throw:
The hot throw of a candle is its scent when lit, and it's where the "real magic happens." A candle with a great hot throw can elevate your space by filling it with fragrance and creating a mood. Heavy, rich scents like vanilla, cinnamon, and conifer tend to deliver a more potent hot throw. When evaluating a candle's hot throw, consider the following factors:
- Fragrance: Note how the fragrance fills the room and the mood it creates.
- Wick size and type: Evaluate the wick's impact on consistent burning and fragrance diffusion. A full melt pool is crucial for a strong hot throw, so choose a wick that achieves this.
- Burn time: Understand that the scent throw often increases after the wax has formed a full melt pool.
- Room size: Consider the size of the room where you'll be burning the candle. A candle with a solid hot throw can fill larger areas, while a milder hot throw may be preferable for smaller spaces.
- Environmental factors: Recognize that factors like high ceilings, humidity levels, and drafty rooms can influence how the hot throw is perceived.
- Personal preference: If you want a bold fragrance that fills the room, focus on candles with a strong hot throw.
By comprehensively evaluating the hot and cold throw of a candle, you can make informed decisions about which candles best suit your preferences and specific spaces.

Wick testing: which wick works and which doesn't
Wick testing is a crucial step in candle-making that ensures your candles burn safely, efficiently, and to their full potential. The right wick can make or break the performance of your candle, affecting everything from the size of the flame to how evenly the wax melts.
To test which wick works best, pour 3 to 5 candles that are all the same except for wick size. Choose the wick size you think you may need and then also select the next size(s) up and down, which should give you an idea of what wick size works best after testing. For example, if you think an ECO-8 wick is suitable for a particular candle recipe, you may also want to test an ECO-6 and an ECO-10. Once they have cured, burn them next to each other to see which wick size performs the best. You can also use this method to determine the best wick type for a specific candle recipe.
When testing, it is recommended to do at least three test burns before making a final decision on which wick size or type to use. Each test burn should be around 2 to 3 hours (possibly shorter or longer, depending on the candle diameter) to allow time for a full melt pool to form. The candle should achieve a full melt pool that is 1/4" to 1/2" deep within 1 hour for each inch of diameter. For instance, a 2" diameter candle should achieve a full melt pool within 2 hours. If there isn't a full melt in 2-3 hours, you may need to move up in wick width.
The flame should be approximately 1/2" to 2" in height, with smaller candles closer to 1/2" and larger candles reaching up to 2". The flame should not produce excess smoke, soot, or mushrooming. It should also not flicker or dance around but should be a still, steady flame.

Burn cycles: how the candle performs over multiple cycles
When testing a candle over multiple burn cycles, it's important to evaluate how the candle performs from start to finish, rather than just during the first few burns. Here are some key factors to consider when testing candle burn cycles:
Multiple Burn Sessions:
Each candle will likely go through multiple burn sessions, so it's important to stay organized. Label each candle jar or use a simple numbering system to keep track of which candle is which. This is especially helpful when testing different combinations of fragrances, waxes, and wicks.
Consistent Testing Environment:
Ensure that each burn cycle is conducted in a controlled environment with moderate ambient temperature and no drafts. This helps isolate the variables affecting the candle's performance.
Timing and Duration:
Note the time you start and stop burning each candle. A typical burn duration for testing is 3-4 hours, allowing the candle to cool for at least 5 hours before the next burn cycle.
Melt Pool:
Observe the melt pool diameter and depth during each burn cycle. After lighting the candle, the melt pool should reach the full diameter of the candle within 2-3 hours. If it doesn't, it may indicate that the wick is too small or too long. If the melt pool grows faster than 1 inch per hour and exceeds a depth of 1/4 inch after a 4-hour burn cycle, consider using a smaller wick.
Soot:
Check for soot residue on the glass during and after each burn cycle. A small amount of soot is normal, especially with paraffin wax, which produces dark soot. However, excessive soot may indicate an issue with the wick size, fragrance load, or fragrance oil used.
Flame Size and Movement:
Most flames will be around 1 inch tall, with normal flames reaching up to 2 inches. During the burn, the flame should be relatively still, with slight movement. As the wax level lowers and heat builds, expect to see more movement in the flame. Excessive flame movement may indicate a draft in the room.
By evaluating these factors over multiple burn cycles, you can gain valuable insights into how your candle performs consistently and make any necessary adjustments to the wick size, fragrance load, or wax type to ensure optimal burning results.

Frequently asked questions
Before you begin burning your candle, make sure to record the candle specifications, including the type of wax, fragrance oil, scent concentration, dye use, wick selection, and container dimensions. You should also note the temperatures you worked with for melting the wax, adding fragrance oil and dye, and pouring once mixed.
During the burn test, you should record the burn rate and duration, as well as any observations about melt pool diameter, tunnelling, and soot residue on the glass. You can also assess the candle's fragrance when burning ('hot throw') and compare it to its fragrance when it's not lit ('cold throw').
Before conducting a burn test, clear your schedule and set up your candles in a comfortable, draft-free area. Place candles 3 to 6 inches (7.6-15.2 cm) apart if testing more than one at a time. Label each candle jar or use a simple numbering system to keep track of multiple burn sessions. Trim the wick to 5mm or 1/4 inch (6 mm) before each test.
It's important to evaluate the candle's performance over multiple burn cycles. Wait until at least the fourth burn cycle before making any conclusions about your wick choice or fragrance oil selection. Observe for issues such as tunnelling, frosted candles, or excess wax hang-up, which may indicate a need for wick adjustments.
