Tallow candles are a great option for emergencies or power outages, but they can be tricky to make. One of the most common issues is that the candles don't harden properly, often due to the type of fat used. To harden tallow candles, you can add beeswax, paraffin wax, or a commercial hardener like stearic acid. You can also place the candles in the refrigerator or freezer to harden, but this may not be a long-term solution as tallow softens at room temperature. Using leaf lard instead of suet and straining the tallow through cheesecloth can also help create a harder candle.

What You'll Learn
Add beeswax, paraffin wax, or vybar to tallow
Tallow candles can be hardened by adding beeswax, paraffin wax, or vybar to tallow. The amount of beeswax or paraffin wax to be added depends on the desired hardness of the candle and the type of fat used to make the tallow. For example, sheep fat is hard, but cow fat is harder, and deer, goat, and elk fats make the hardest tallow.
Beeswax helps to harden tallow and reduce its odour, as it has a pleasant, natural smell. It can be melted in the same way as paraffin or tallow and can be moulded by hand or with a warm knife. Different ratios of tallow to beeswax can be experimented with to find the ideal consistency, such as 80/20, 70/30, or 75/25. However, one user reported that even with these ratios, their candles had issues with the melt pool, tunnelling, or burning low.
Paraffin wax can also be added to tallow to increase its hardness. It is a common ingredient in candle-making and can be melted and moulded like beeswax and tallow.
Vybar, a type of hardening agent, can be added to tallow and beeswax to further increase the hardness of the candle. However, finding the right ratio of tallow, beeswax, and vybar can be challenging, as too much vybar can cause the candle to tunnel or go out.
Other substances that can be used to harden tallow include alum and stearic acid. Alum is readily available at local pharmacies, while stearic acid can be ordered from candle-making suppliers.

Use leaf lard instead of suet
Tallow candles are a great, inexpensive and non-toxic alternative to modern candles. They are easy to make and can be stored for use during emergencies or power outages.
One of the challenges in making tallow candles is achieving the right consistency. Tallow candles that are too soft may melt and ruin equipment, especially in warmer climates. To harden tallow candles, some candle makers add beeswax, paraffin wax, or stearic acid to the tallow. However, these additives may increase costs and affect the candle's scent and burning characteristics.
An alternative approach to hardening tallow candles is to use leaf lard instead of suet as the primary fat. Leaf lard is a type of fat derived from the abdominal area of pigs. It has a higher melting point than other types of lard, making it ideal for candle-making. By using leaf lard, you can create tallow candles that are firmer and more stable, especially in warmer temperatures.
- Source high-quality leaf lard: Look for leaf lard from a reputable supplier, preferably one that offers organic or pasture-raised pork products. The quality of the leaf lard will impact the final product, so it's worth investing in a good source.
- Render the leaf lard properly: Rendering is the process of melting and purifying the fat. Follow instructions specific to rendering leaf lard for candle-making, ensuring that you remove any impurities to avoid rancid smells.
- Test different proportions: Experiment with different ratios of leaf lard to tallow to find the ideal balance. You may need to adjust the amount of leaf lard added based on the consistency of your tallow and the desired hardness of the final candle.
- Monitor the melting point: Keep an eye on the melting point of your candles as you add leaf lard. A higher melting point indicates a harder candle, but be cautious not to raise it too high, as this may affect the candle's ability to burn properly.
- Scent and colour customization: Leaf lard's neutral scent and colour make it an excellent base for customization. You can add essential oils, fragrances, or even use scented crayons to create unique, pleasant-smelling candles.
- Wick selection: As the hardness of your candles changes, you may need to adjust the type and size of the wick used. Experiment with different wicks to find the optimal combination that provides a clean burn and minimizes tunneling.
By following these steps and making adjustments based on your specific needs, you can create firm and stable tallow candles using leaf lard instead of suet. This approach offers a natural solution to hardening tallow without relying on additional additives, resulting in high-quality, non-toxic candles that are well-suited for everyday use or emergency situations.

Refrigerate or freeze candles
Refrigerate or freeze your tallow candles to harden them. One source recommends refrigerating tallow after it has been melted and strained to remove impurities and prevent rancid smells. The tallow can then be melted again over low heat and poured into candle moulds or jars. Another source suggests placing candles in the refrigerator to harden.
Freezing tallow candles is also an option. One source recommends freezing tallow candles overnight to harden the tallow and prevent them from melting quickly when lit. Another source mentions freezing containers of rendered beef fat, or tallow, and then melting the tallow over low heat.
Refrigerating or freezing tallow candles can help to speed up the hardening process and prevent melting. However, it is important to note that tallow is typically a solid at room temperature, with a melting point of 108-113 degrees Fahrenheit. Therefore, it may not be necessary to refrigerate or freeze tallow candles for them to harden, and doing so may only be beneficial in certain circumstances, such as in hot climates or to accelerate the hardening process.

Use a commercial hardener like stearic acid
If you're looking for a way to harden your tallow candles, one option is to use a commercial hardener like stearic acid. Stearic acid is a fatty acid that can be added to candle wax to make it harder and improve its melting properties. It is often used in candle-making to create harder, more durable candles.
When using stearic acid to harden tallow candles, it is important to use the correct ratio of tallow to stearic acid. Too much stearic acid can make the candle too hard and difficult to burn, while too little may not have a significant impact on the hardness of the candle. Experiment with different ratios to find the perfect balance for your candles.
To use stearic acid, simply melt your tallow as you normally would when making candles. Once the tallow is melted, add the desired amount of stearic acid and stir until it is fully dissolved. You can then proceed with pouring your candles as usual.
It is worth noting that stearic acid can be quite pricey. If you are looking for a more cost-effective solution, you may want to consider using beeswax or paraffin wax as a hardener instead. However, if you are specifically looking for the hardening properties of stearic acid, it is a great option to create durable and long-lasting tallow candles.
By using stearic acid, you can ensure that your tallow candles are hard and sturdy, making them ideal for everyday use or emergency situations. With its hardening properties, stearic acid helps to create a consistent burn and improves the overall quality of your homemade tallow candles.

Avoid soft tallow by using beef fat
Tallow candles are inexpensive and easy to make, but they can be soft and prone to melting. This can be an issue, especially in warmer climates, as it may lead to a mess if the candles melt outside of their jars.
To avoid soft tallow, it is important to start with the right type of fat. While lard can be used for candles in a jar, it is too soft for dipped candles and will melt and fall apart. Beef tallow, on the other hand, is a hard fat that is ideal for candles without the support of a jar. When sourcing beef tallow, look for leaf lard or backbone fat, as suet may result in softer candles.
If you are rendering the tallow yourself, be sure to use a cheesecloth to filter out impurities and reduce any unpleasant odours. This step will help improve the final product and make it less likely to turn rancid.
For those who do not have access to beef fat or would like to further harden their tallow, additives such as beeswax, paraffin wax, or stearic acid can be added to the mixture. These additives will increase the melting point of the tallow, making it harder at room temperature. However, it is important to experiment with different ratios to find the right balance, as too much additive may affect the burn of the candle.
