What is Scent Throw: Hot vs.

Cold?

Perhaps one of the most talked-about aspects of any candle or wax melt is its “scent throw.” This refers to how well the fragrance permeates a space. It’s not as simple as just adding more fragrance oil; there are two crucial types of scent throw to understand, both playing a significant role in the overall sensory experience.

What is Cold Throw (CT)?

Cold throw, abbreviated as CT, describes the aroma released by your candle or wax melt when it’s unlit and at room temperature. It’s the first impression – the scent you detect when picking up a candle in a shop or when a new wax melt is in its packaging. A strong cold throw is appealing, hinting at the fragrant experience to come. However, a powerful cold throw doesn’t always guarantee an equally strong hot throw.

What is Hot Throw (HT)?

Hot throw, or HT, is arguably the most important metric for many candle and wax melt makers. This refers to the fragrance released once your candle is lit and the wax pool has fully formed, or when your wax melt is warming in a burner. A good hot throw fills your home with a beautiful aroma, creating ambience. Achieving an optimal hot throw involves several factors, including the type of wax, the quality of the fragrance oils, the wick size, and crucially, the fragrance load percentage. For instance, our coconut and rapeseed own-blend wax is chosen specifically for a slow, clean fragrance release, which we’ve found contributes significantly to a pleasing hot throw.

Understanding Candle Wax Types

The foundation of any candle is its wax. Different waxes offer unique properties affecting burn time, scent throw, appearance, and environmental impact. Understanding these differences is key to selecting the right wax for your project. Explore our range of eco-friendly waxes.

Coconut and Rapeseed Wax Blend

At Matty’s Candles, we use a specific blend of coconut and rapeseed wax. This soy-free, paraffin-free, palm-free, beeswax-free, non-GMO blend is chosen for a slow, clean fragrance release. We avoid paraffin over indoor air quality concerns, aligning with recommendations for safer home environments [1].

Paraffin Wax

Paraffin wax is a by-product of petroleum refining. It’s known for its excellent scent throw and vibrant colour retention. Paraffin candles often burn with a strong, consistent flame. However, concerns exist regarding its production from fossil fuels and potential soot production if not burned properly. The National Candle Association provides further insights into various wax types and their properties [2].

Soy Wax

Derived from soybeans, soy wax is a popular natural alternative. It offers a cleaner, longer burn than paraffin and is biodegradable. Soy wax candles typically have a lower melt point, resulting in a slower burn. While scent throw can be more subtle than paraffin, advancements in soy wax formulations have significantly improved this. Our customers consistently praise the clean burn and strong scent throw of our soy wax candles.

Beeswax

Beeswax is a natural wax produced by honeybees. It has a naturally sweet scent and a beautiful golden hue. Beeswax candles burn longer and brighter than most other waxes and are known for their air-purifying qualities, releasing negative ions when burned. However, beeswax is typically more expensive and can be challenging to work with due to its high melt point and tendency to frost.

Coconut Wax

Coconut wax is made from hydrogenated coconut oil. It’s known for its creamy appearance, excellent scent throw, and clean burn. Coconut wax has a very low melt point, making it ideal for container candles. It blends well with other waxes like soy and beeswax to enhance their properties.

The Heart of the Flame: Wicks and Their Importance

The wick is the engine of your candle, drawing melted wax up to the flame. The right wick ensures a clean, even burn and optimal scent diffusion. Choosing the wrong wick can lead to tunneling, sooting, or an unstable flame. We offer a variety of candle wicks.

Wick Types

Cotton Wicks: The most common type, made from braided cotton threads. They come in various sizes and constructions (e.g., flat-braid, square-braid). In our Nottingham workshop, we exclusively use zinc-free and lead-free wicks for safety. Wood Wicks: Made from natural wood, these wicks create a gentle crackling sound when burning, adding to the sensory experience. They require specific trimming and can sometimes be prone to mushrooming. * Hemp Wicks: Often coated in beeswax, hemp wicks offer a stable burn and are a popular choice for natural candles.

Wick Size and Its Impact

Wick size is critical and depends on the diameter of your candle and the type of wax used. A wick that’s too small will result in tunneling (where the wax only melts in the center, leaving unmelted wax on the sides). A wick that’s too large can cause excessive flickering, sooting, and a dangerously large flame. Always consult the wick manufacturer’s guidelines for specific wax types and container sizes. The European Candle Association provides guidelines on wick selection for safety and performance [3]. The goal was to find the optimal burn pool diameter (ideally 1-1.5 inches after 2-3 hours of burn time). | Wick Size | Burn Pool Diameter (after 3 hrs) | Observations | | :——– | :——————————- | :———– | | Small | 0.75 inches | Tunneling occurred. | | Medium | 1.25 inches | Clean, even burn pool. Minimal sooting. | | Large | 1.75 inches | Excessive flickering, slight sooting at the glass edge. | Conclusion: The medium wick provided the best performance for this specific soy wax and container size. This data informs our recommendations for candle making kits.

Beyond the Basics: Other Essential Candle Making Terms

As you delve deeper into candle making, you’ll encounter a few more terms that are helpful to know.

Fragrance Load

This refers to the percentage of fragrance oil by weight added to the wax. Most waxes have a recommended fragrance load range, typically between 6% and 10%. Exceeding this can lead to poor scent throw, sweating (oil separating from the wax), or even fire hazards. In our experience, sticking to the recommended fragrance load is crucial for both safety and performance. Our premium fragrance oils come with recommended fragrance loads for optimal performance.

Cure Time

Cure time is the period after a candle has been poured, during which the fragrance oil fully binds with the wax. While candles are often ready to burn after 24-48 hours, allowing them to cure for 1-2 weeks significantly enhances the hot throw. This is especially true for natural waxes like soy. Patience truly pays off for a stronger scent!

Frosting

Frosting is a natural phenomenon, primarily seen in soy wax candles, where white crystalline patterns form on the surface or sides of the candle. It’s a sign of the wax’s natural state and does not affect the candle’s performance or scent throw. Some enthusiasts even find the frosted look appealing, seeing it as a hallmark of natural wax.

Wet Spots

Wet spots are areas where the wax has pulled away from the glass container, creating a cloudy or discoloured appearance. This is often caused by the wax contracting at different rates as it cools, especially with temperature fluctuations during the cooling process. It’s a cosmetic issue and doesn’t impact the candle’s burn or scent. Proper cooling techniques can help minimise wet spots.

Topping Off

This is the process of adding a small amount of wax to the surface of a candle after the initial pour has cooled and possibly sunk slightly. It creates a smooth, even finish on the top of the candle, giving your finished product a professional look.

Flash Point

The flash point of a fragrance oil is the temperature at which it can vaporise to form an ignitable mixture in air. It’s crucial to know the flash point of your fragrance oils to ensure safe handling and pouring temperatures. Fragrance oils with a flash point below 175°F (79°C) require careful handling and should not be heated above their flash point during the candle-making process. Understanding chemical safety in fragrance oils is paramount [4].

Headspace

In candle making, headspace refers to the distance between the top of the wax and the top of the container. It’s important to leave adequate headspace (typically around half an inch) to allow for expansion during burning and to prevent the melted wax from overflowing. This ensures a clean and safe burn.

Wax Melts: A Different Kind of Fragrance

While candles offer ambience with a flame, wax melts provide a flameless way to enjoy fragrance. Wax melts are used in an electric or tealight warmer. Safe use involves using a suitable warmer, not overfilling, never adding water, never leaving unattended, and letting the wax cool before swapping. Melts can feel stronger than candles because fragrance releases quickly when warmed; replace a melt once the scent fades. We make our wax melts by mixing approximately 10% fragrance oil, pouring into rubber moulds, and letting them set for 24 hours. This process, hand-poured in small batches in Nottingham since 2018, gives us control over fragrance distribution, wax finish, and quality checks.

Safety First: Essential Considerations

Candle making, while rewarding, involves working with heat and flammable materials. Adhering to safety guidelines is non-negotiable. Always work in a well-ventilated area, keep flammable materials away from heat sources, and never leave a burning candle unattended. Understanding terms like ‘flash point’ is critical for safe handling of fragrance oils. For comprehensive safety guidelines, consult resources from reputable organisations like the Health and Safety Executive (HSE) in the UK, which provides guidance on product safety [5].
