Gloss coatings are used to give candles a luxurious, glossy finish, enhancing their aesthetic appeal. However, the question of whether these gloss coatings can catch fire is a safety concern for many. While some clear gloss coatings are flammable, this is typically only the case when they are in an aerosol form or during application. Once dried, most gloss coatings are not flammable and can be safely used on candles. Nevertheless, it is essential to follow general candle safety guidelines, such as never leaving a burning candle unattended and keeping them away from flammable objects.

What You'll Learn
Gloss coatings can be flammable
While a gloss coating can enhance the appearance of candles, it is important to consider the potential flammability of such coatings. Some clear gloss coatings are highly flammable, particularly during application due to the aerosols and solvents used. This flammability tends to decrease once the coating has dried or cured, but it is crucial to follow safety precautions to prevent accidents.
The level of flammability of a gloss coating depends on various factors, including the specific product and its ingredients, as well as the application and curing processes. Some coatings may have higher flammability than others due to their chemical composition. It is always advisable to read the product labels, safety data sheets, and manufacturer instructions to understand the flammability characteristics and proper handling procedures.
When applying a gloss coating to a candle, it is essential to work in a well-ventilated area to minimize the risk of igniting fumes. Additionally, ensuring that the room temperature is consistently above 72 degrees Fahrenheit can aid in properly curing the coating, reducing its flammability. Allowing sufficient drying or curing time before lighting the candle is critical to enhancing the coating's fire resistance.
To minimize the risk of fire, it is crucial to follow general candle safety guidelines. This includes never leaving a burning candle unattended, keeping it away from flammable objects and surfaces, and maintaining a safe distance from children and pets. Regularly trimming the wick to a length of 1/4 inch also helps prevent uneven burning, dripping, or flaring.
While there are gloss coatings specifically designed for candle-making that are advertised as fire-safe, it is important to exercise caution. Even these products should be used with proper ventilation during application and allowed to dry thoroughly before lighting the candle. Always follow the manufacturer's instructions and take the necessary precautions to ensure a safe candle-burning experience.

Fire safety tips for candles
Candlelight creates a cosy atmosphere and is an important part of many celebrations, but it is important to remember that an open flame can be dangerous. A study by the U.S. Consumer Product Safety Commission suggests that 85% of candle fires could be avoided if consumers followed three basic safety rules.
- Never leave a burning candle unattended. Always blow out candles when you leave a room or go to bed, and never use lit candles in bedrooms, bathrooms, or sleeping areas.
- Keep candles away from flammable objects, such as furniture, drapes, bedding, carpets, books, paper, and decorations. Place burning candles at least 12 inches apart from one another and from any flammable objects.
- Use a candleholder that is specifically designed for candle use. It should be heat-resistant, sturdy, and large enough to contain any drips or melted wax.
- Keep candles out of the reach of children and pets. Do not place lighted candles where they can be knocked over by children, pets, or anyone else.
- Before lighting a candle, trim the wick to ¼ inch. Long or crooked wicks can cause uneven burning, dripping, or flaring. Keep the wax pool clear of wick trimmings, matches, and debris.
- Do not touch or move a candle while it is burning or while the wax is liquefied. Discontinue burning a candle when ½ inch of wax remains in the container or 2 inches if using a pillar candle.
- Extinguish a candle if the flame becomes too high or flickers repeatedly.
- Avoid drafts, vents, or air currents, as these can cause rapid or uneven burning, sooting, and excessive dripping.
- Always follow the manufacturer’s recommendations on burn time and proper use.
In addition to these safety tips, consider using battery-operated flameless candles, which can look, smell, and feel like real candles without the risk of fire.

Non-flammable gloss coatings
Gloss coatings are often used to give a decorative finish to candles and candle holders. However, some people are concerned about the potential fire hazards of these coatings, especially when applied to wooden candle holders. While some gloss coatings are flammable, there are non-flammable options available that can provide a safe and attractive finish.
One example of a non-flammable gloss coating is the SUHS-A clearcoat, which is a water-based, aliphatic polyurethane-type acrylic clearcoat. This product meets the Euroclasse FEU classification, which rates the fire reaction and resistance of materials. The SUHS-A clearcoat is classified as A2, indicating that it has been tested and proven to retard the spread of flames.
Another option for a non-flammable gloss coating is the FP100 Fire Retardant Clear Coat. This product is designed for use on wood and plastic surfaces and is intumescent, meaning it swells and forms a protective char layer when exposed to heat or flame. This char layer acts as a thermal barrier, protecting the underlying material from combustion. The FP100 coating also has the added benefit of being a waterproofing agent, mould and mildew inhibitor, and insect repellent.
When choosing a non-flammable gloss coating, it is important to consider the specific application and surface being treated. Some coatings may be better suited for outdoor use, while others may be specifically designed for use on certain materials, such as wood or plastic. It is also essential to follow the manufacturer's instructions for proper application and curing to ensure the effectiveness of the coating.

Methods to achieve a gloss finish
A glossy finish on candles can be achieved through a combination of carefully selected materials, innovative techniques, and precision in the manufacturing process. Here are some methods to achieve a gloss finish on candles:
Wax Blends and Additives
The choice of wax blend significantly influences the candle's finish, durability, and overall appeal. Paraffin wax, for instance, offers superior smoothness and gloss when properly cooled. Beeswax is another option known for its natural sheen, but it may require additives like stearic acid or Vybar to achieve a higher gloss. Polyethylene wax is also a versatile additive that improves gloss, durability, and surface quality.
Cooling Techniques
The cooling process plays a critical role in achieving a flawless, glossy surface. Slow cooling promotes smaller, evenly distributed crystals, resulting in a smooth and glossy finish. To achieve this, candle makers can use heat retention jackets, such as thermal foil or silicone sleeves, to slow down the cooling process. Alternatively, precision cooling systems, like digitally controlled cooling cabinets, can maintain specific temperatures and humidity levels for consistent results.
Gloss Overdip and Candle Varnish
For a quick and simple solution, gloss overdip involves melting enough wax to submerge the entire candle, creating a glossy finish. Candle varnish is another option that can produce impressive results. These methods are particularly effective when working with multiple candles, as they enhance the visual appeal and protect against fingerprints and damage during handling.
Spray Painting and Clear Coats
Spray painting and clear coats can be applied to candlesticks or candle vessels to achieve a high-gloss finish. However, it is important to ensure that the products are properly cured and dried to prevent flammability. Most sealants require a consistent temperature of at least 72°F (22.2°C) or higher to fully cure. Always refer to the manufacturer's instructions and warnings before use.
Sculpd Glossy Clear Coat
Sculpd offers a glossy clear coat candle-making acrylic varnish that is fire-safe, scratch-resistant, and suitable for clay candles and pottery. It provides a high-gloss finish and protects your creations. It is recommended to apply two coats, waiting 1-2 hours between each coat, and letting it set completely overnight before pouring your wax.
