What You'll Learn

Bacon Grease as Wax Alternative
While traditional candle-making relies heavily on wax, a surprising alternative lurks in your kitchen: bacon grease. Yes, the rendered fat from cooking bacon can be transformed into a viable, if unconventional, candle fuel. This practice, though not mainstream, has gained traction among DIY enthusiasts and those seeking sustainable, resourceful solutions.
Before diving into the process, it's crucial to understand the properties of bacon grease. Unlike wax, bacon grease is an animal fat, composed primarily of triglycerides. This means it burns differently, producing a unique scent and requiring specific considerations for successful candle-making.
Preparation is Key:
The first step is rendering the bacon grease. This involves cooking bacon as usual, but instead of discarding the grease, collect it in a heat-safe container. Allow it to cool slightly, then strain it through a fine-mesh sieve or cheesecloth to remove any solid particles. For optimal results, refrigerate the strained grease overnight. This will cause any remaining impurities to solidify on the surface, allowing for easy removal.
The rendered grease should be a pale yellow, semi-solid fat at room temperature. If it's too liquid, further refrigeration is needed.
Wicking and Container Selection:
Choosing the right wick is crucial for bacon grease candles. Due to the grease's lower melting point compared to wax, a thicker wick is recommended. Cotton wicks with a larger diameter, such as those used for soy wax candles, work well.
Container selection is equally important. Opt for heat-resistant glass jars or tins that can withstand the burning temperature of the grease. Avoid using containers with narrow openings, as the wider surface area allows for better oxygen flow and a more even burn.
The Candle-Making Process:
Melt the prepared bacon grease in a double boiler, ensuring it doesn't reach smoking point. Carefully pour the melted grease into your chosen container, leaving enough space at the top for the wick. Secure the wick in place by dipping the metal tab in the melted grease and centering it in the container. Allow the candle to cool completely at room temperature, which may take several hours.
Burning and Considerations:
Bacon grease candles burn with a unique, savory aroma reminiscent of cooked bacon. However, this scent can be overpowering for some. Burning time is generally shorter than traditional wax candles due to the lower melting point of the grease. It's essential to never leave a burning candle unattended and to ensure proper ventilation.
Important Notes:
- Safety First: Always exercise caution when handling hot grease.
- Shelf Life: Bacon grease candles have a shorter shelf life than wax candles and should be used within a few months to prevent rancidity.
- Experimentation: This is a DIY project, so feel free to experiment with different bacon types (smoked, peppered) for varying scents and colors.
Using bacon grease as a wax alternative is a creative and resourceful way to repurpose kitchen scraps. While it requires some adjustments and considerations, the resulting candles offer a unique, aromatic experience for those willing to explore beyond traditional candle-making methods.

Melting and Pouring Techniques
When using bacon grease to make candles, mastering the melting and pouring techniques is crucial for achieving a smooth, even finish. Begin by preparing your bacon grease by straining it through a fine mesh strainer or cheesecloth to remove any solid particles. This ensures that your candle will burn cleanly and look aesthetically pleasing. Place the strained bacon grease in a double boiler or a heat-safe container set over a pot of simmering water. This indirect heating method prevents the grease from burning or scorching, which can affect the scent and quality of your candle. Heat the grease slowly, stirring occasionally, until it reaches a fully liquid state.
Once the bacon grease is completely melted, it’s essential to monitor the temperature carefully. Ideal pouring temperatures for bacon grease candles typically range between 160°F and 180°F (71°C to 82°C). Use a candy or digital thermometer to ensure accuracy. If the grease is too hot, it can cause air bubbles or shrink as it cools; if it’s too cold, it may not pour smoothly or adhere well to the container. While the grease is melting, prepare your candle containers by securing the wicks at the center. You can use wick stickers or a small amount of melted grease to hold the wick in place, ensuring it stays upright during the pouring process.
When the bacon grease reaches the desired temperature, remove it from the heat source and let it sit for a minute or two to allow any foam or impurities to settle. Gently stir the grease to ensure consistency, then carefully pour it into your prepared containers. Pour slowly and steadily, leaving about ¼ inch of space at the top to allow for shrinkage as the candle cools. If you’re adding fragrance oils or essential oils, do so just before pouring, stirring gently to incorporate without introducing air bubbles. Avoid over-stirring, as this can also cause bubbles.
After pouring, the candles will begin to cool and solidify. To minimize cracking or uneven surfaces, place the containers on a flat, stable surface and avoid moving them for at least 4 to 6 hours. If you notice any dips or uneven areas as the candles cool, you can carefully reheat a small amount of bacon grease and use it to fill in these spots. However, this should be done sparingly and only if necessary, as multiple pours can affect the overall appearance.
Finally, once the candles are completely cooled and solidified, trim the wicks to about ¼ inch above the wax surface. This ensures a clean burn and prevents excessive smoking. Bacon grease candles may have a subtle savory scent, but you can experiment with adding fragrances to create unique aromas. Proper melting and pouring techniques not only enhance the visual appeal of your candles but also contribute to their overall performance and longevity. With patience and attention to detail, you can create beautiful, functional candles using this unconventional yet resourceful material.

Scent and Smoke Considerations
When considering using bacon grease to make candles, scent and smoke considerations are paramount. Bacon grease inherently carries a strong, savory aroma that can dominate any space when burned. While some may find the scent of bacon appealing, it’s important to note that this fragrance may not be suitable for all environments or preferences. If you intend to use the candle in a living area or bedroom, the overpowering smell of bacon could become cloying over time. To mitigate this, consider blending bacon grease with unscented wax or adding essential oils to create a more balanced aroma. For example, pairing bacon grease with a smoky or woody essential oil like cedarwood or sandalwood can complement the natural scent without overwhelming the senses.
Another critical aspect of scent and smoke considerations is the smoke produced when burning bacon grease candles. Animal fats like bacon grease tend to burn at higher temperatures and can produce more smoke than traditional candle waxes, such as soy or paraffin. This increased smoke output can be a concern for indoor air quality, especially for individuals with respiratory sensitivities or allergies. To reduce smoke, ensure the wick is properly trimmed and centered, as a well-maintained wick promotes cleaner burning. Additionally, consider using a container with a lid to control the burn and minimize smoke dispersion when the candle is not in use.
The scent and smoke considerations also extend to the longevity and consistency of the candle’s fragrance. Bacon grease may not hold added scents as effectively as commercial waxes, causing the aroma to fade quickly. To address this, experiment with higher concentrations of essential oils or fragrance oils, but be cautious not to exceed the recommended ratios, as this can affect the candle’s burn quality. Regularly testing the candle’s scent throw—both cold and hot—will help you determine the optimal fragrance load for a lasting aroma.
For those concerned about the smoky residue that bacon grease candles may leave behind, scent and smoke considerations should include the choice of additives. Incorporating a small amount of stearic acid or vybar into the wax mixture can improve burn stability and reduce soot. These additives act as hardeners, helping the candle maintain its shape and burn more cleanly. However, be mindful that even with additives, bacon grease candles may still produce more smoke than traditional candles, so proper ventilation is essential.
Lastly, scent and smoke considerations should factor in the environmental impact of burning bacon grease candles. While repurposing bacon grease is a sustainable practice, the increased smoke and potential for soot can contribute to indoor air pollution. If sustainability is a priority, balance this by ensuring the candle is burned in a well-ventilated area and for shorter durations. Alternatively, consider using bacon grease in combination with eco-friendly waxes like soy or beeswax to create a cleaner-burning candle that still retains a unique, savory scent. By carefully addressing these considerations, you can create a bacon grease candle that is both fragrant and functional.

Wick Selection for Grease Candles
When making candles from bacon grease, wick selection is a critical factor that can significantly impact the candle's performance. Unlike traditional wax candles, grease candles have unique properties that require careful consideration when choosing a wick. The primary goal is to ensure the wick can effectively draw up the grease and provide a steady, even burn. Grease is denser and burns differently than wax, so standard candle wicks may not always be suitable. It’s essential to select a wick that is both absorbent and durable enough to handle the viscosity of the grease.
For grease candles, cotton wicks are often the preferred choice due to their natural absorbency and ability to withstand higher temperatures. However, not all cotton wicks are created equal. Braided cotton wicks, particularly those with a higher ply count, tend to perform better because they provide a larger surface area for absorption. This is crucial for grease candles, as the wick needs to draw up the thicker material efficiently. Flat cotton wicks, on the other hand, may struggle to maintain a consistent flame due to their smaller surface area. When selecting a cotton wick, consider the diameter of the candle and choose a wick size that matches—larger candles will require thicker wicks to ensure proper burning.
Another important consideration is the wick’s treatment. Wicks often come pre-coated with wax or other materials to enhance their rigidity and burn stability. For grease candles, untreated cotton wicks are generally recommended because the grease itself will coat the wick as it burns. Pre-waxed wicks may not perform as well since the wax coating could interfere with the grease’s ability to adhere to the wick. If you’re unsure, test both treated and untreated wicks to see which performs better with your specific grease mixture.
Wooden wicks are another option, though they are less commonly used for grease candles. While wooden wicks can create a unique crackling sound and aesthetic appeal, they may not be as efficient at drawing up grease due to their rigid structure. If you decide to experiment with wooden wicks, opt for smaller sizes and ensure the grease is properly melted and strained to reduce any debris that could clog the wick. Keep in mind that wooden wicks may require more frequent trimming to maintain a clean burn.
Lastly, testing is key to finding the perfect wick for your grease candles. Start by making a small batch and trying different wick types and sizes to observe their performance. Look for a wick that provides a steady flame, minimal sooting, and complete grease consumption. Remember that the wick’s performance can also be influenced by factors like the grease’s temperature during pouring and the candle’s container size. With patience and experimentation, you can select the ideal wick to create clean-burning, long-lasting bacon grease candles.

Safety and Burn Quality
While it might seem like a creative way to repurpose kitchen scraps, using bacon grease to make candles comes with significant safety and burn quality concerns that should not be overlooked. Firstly, bacon grease is an animal fat, and unlike traditional candle waxes such as soy or paraffin, it has a low melting point and a high risk of smoking excessively when burned. This can lead to poor air quality and the release of potentially harmful particles into your environment. Additionally, the smoke produced by burning animal fats can have a strong, unpleasant odor that lingers long after the candle is extinguished.
From a safety perspective, bacon grease candles pose a fire hazard due to their unpredictable burn behavior. Animal fats like bacon grease can splatter when heated, especially if not properly filtered or prepared. This splattering can cause hot grease to escape the candle container, potentially igniting nearby flammable materials or causing burns. Moreover, bacon grease has a tendency to burn unevenly, which can lead to tunneling or the formation of deep holes in the candle, further increasing the risk of uncontrolled flames or wax overflow.
Another critical safety issue is the potential for bacterial growth in bacon grease candles. Unlike commercially produced candle wax, bacon grease is not sterile and can harbor bacteria, especially if not stored or handled properly. When burned, these bacteria may release toxins or contribute to indoor air pollution. To mitigate this risk, the grease would need to be thoroughly cleaned, filtered, and possibly treated with preservatives, which adds complexity and uncertainty to the process.
In terms of burn quality, bacon grease candles are unlikely to provide the consistent, clean burn associated with traditional candles. The low melting point of bacon grease means the candle will burn quickly and unevenly, resulting in a shorter lifespan and poor performance. Additionally, the natural impurities in bacon grease can cause the wick to clog or burn inefficiently, leading to frequent extinguishing or sooting. This not only diminishes the candle's aesthetic appeal but also increases the likelihood of safety issues.
For those still considering experimenting with bacon grease candles, it is essential to prioritize safety measures. Use a heat-resistant container with a secure lid to minimize splatter risks, and always keep the candle away from flammable materials. Opt for a thick, stable wick designed for high-melt waxes to improve burn consistency. However, given the inherent risks and poor burn quality, it is strongly recommended to stick with tried-and-true candle-making materials like soy wax, beeswax, or paraffin for a safer and more enjoyable experience.
