What Kind Of Wicks Are Food Safe?

Food safe wicks are wicks that are specifically designed to be used in candles where the wax will be ingested. They are made from materials that are non-toxic and will not contaminate the wax when burned (StupidFood, 2023). The purpose of food safe wicks is to allow candles made from edible ingredients like oils, butters, and sugars to be safely consumed without ingesting harmful chemicals from the wick.

Food safe wicks enable the creation of edible candles for novelty foods, desserts, and drink garnishes. They allow the wax to be flavored with spices, herbs, citrus, and more to impart taste and aroma when the melted wax is poured over foods. Common uses include adding a savory herb flavor to meat dishes, infusing butter for bread dips, and adding sweet scents like vanilla to drinks or desserts (Storables, 2023).

Cotton Wicks

Cotton wicks are one of the most common types of wicks used for candles and food safe purposes. Cotton is a natural fiber made from the cotton plant. As a wick material, cotton offers some key benefits:

Cotton is a very absorbent material, which allows it to soak up melted wax or oils efficiently. This absorption helps the wick bring fuel to the flame at an even rate, allowing for a nice steady burn. The capillary action of cotton fibers pulls the melted fuel up the wick.

The natural fibers of cotton also promote an even burn when lit. The wick bends as it burns, which exposes new cotton fibers to the flame and prevents tunneling. This results in full combustion of the wick.

Overall, cotton wicks are a natural choice appreciated for their absorbency and clean, long-lasting burn. Many candle makers and food artists turn to cotton as a safe and effective wick when purity and performance are priorities.

Wooden Wicks

Wooden wicks are made from natural wood fibers like bamboo or wood splints. They allow more air flow to the candle flame, which makes the flame burn hotter and brighter. As the wick burns, the wood fibers crackle and pop, creating a pleasant, fireside sound.

Wooden wicks do not contain any materials like zinc or lead that could contaminate melted candle wax. This makes them a food-safe option for edible candles. According to sources on Reddit, most wooden wicks purchased from craft stores are coated in either beeswax or paraffin wax, both of which are edible [1].

However, it’s still best to purchase wooden wicks specifically marketed as food-safe or edible. These are coated with food-grade ingredients and made from untreated natural materials. Look for food-safe wooden wicks online or at specialty cooking stores.

Paper Wicks

Paper wicks are a popular choice for many candle makers. They are often made from natural fibers like cotton or wood pulp. Paper wicks have several advantages:

• Inexpensive – Paper wicks tend to be very affordable, especially when buying in bulk quantities.
• Natural Materials – Since they are usually made from plant-based fibers like cotton, paper wicks are generally considered natural and eco-friendly.
• Easy to Use – Their soft, flexible structure makes paper wicks easy to work with when constructing candle wicks.

However, paper wicks also come with some potential drawbacks:

• Tunneling – The loose weave of some paper wicks can lead to tunneling, where the wax melts unevenly around the wick.
• Sooting – Paper fibers may leave more soot on wick and jar surfaces as they burn.
• Durability – Paper wicks can be prone to breakage, fraying, and bending compared to stiffer wick materials.

Testing different paper wick types and pairing them with the appropriate wax blend can help minimize these issues. Some candle makers also pair paper wicks with a secondary wick material for stability. With proper wicking, paper wicks can be an excellent low-cost wicking option.

Zinc Core Wicks

Zinc core wicks contain cotton braids with a zinc core at the center. The zinc provides rigidity so that the wick can stand upright and retain its shape, allowing for consistent and even burning (Hive and Honey Candle Co., The Flaming Candle). Zinc core wicks are durable and long-lasting making them a popular choice for containers, pillars, votives and tealights. However, zinc core wicks produced before 1974 may contain lead. Lead-containing wicks can release toxic fumes when burned so it’s important to ensure any zinc core wicks used today are lead-free (Wellington Fragrance).

Eco-Friendly Wicks

Eco-friendly wicks are made from natural, sustainable materials like cotton, wood, paper, and hemp. They are designed to burn cleaner and produce less soot than standard paraffin wax candles (Vovk, 2022). Some key features of eco-friendly wicks include:

Made from sustainable materials: Eco-friendly wicks may contain organic cotton, untreated wood, unbleached paper, or even hemp fiber. These renewable materials are biodegradable and support sustainable agriculture practices (Hive and Honey Candle Co).

Biodegradable: Unlike wire-core wicks which contain metals, eco-friendly wicks fully biodegrade after use. This makes them more environmentally friendly and ideal for outdoor use (The Flaming Candle).

Less smoke/soot: The natural fibers in eco-friendly wicks burn cleaner and produce less soot than standard paraffin or lower-quality wicks. They are designed to self-trims as they burn down, reducing smoke output (Vialhis).

Wick Safety

When shopping for candle wicks, it is important to avoid lead or zinc coated options. Lead and zinc can produce toxic fumes when burned, posing health hazards especially for children (CPSC Bans Candles With Lead-Cored Wicks, 2003). Always check the label or product description for the wick material. Most wicks today are made from cotton, wood, or paper. However, some low quality or imported candles may still contain metal core wicks.

The U.S. Consumer Product Safety Commission banned lead-cored wicks in 2003 due to the dangers of lead exposure through candle emissions (CPSC Bans Candles With Lead-Cored Wicks, 2003). Consumers should be vigilant and avoid any candle that specifies a zinc, tin, or lead core wick. Metal-core wicks can break down over time with heat exposure and release heavy metals into the air when burned. Even candle wicks labeled as “lead-free” may contain trace amounts of lead that could be unsafe, especially with prolonged burning.

Always check the wick material before purchasing candles, and trim wicks to 1⁄4 inch before lighting to reduce toxic emissions. Properly maintained cotton, wood, or paper wicks are the safest options for health and do not release dangerous fumes (Candle Safety, n.d.).

Wick Maintenance

Wicks should be trimmed to 1⁄4 inch before lighting, according to the Wildwood Candle Company. Long wicks can cause excess smoke and leave black soot on your candle and walls. Trimming the wick will help prevent tunneling, allowing for an even, complete burn. The wicks should be trimmed each time the candle is lit.

Avoid drafts, advises Fire and Flow, as they can cause tunneling of candle wicks. Drafts from open windows, fans, vents, or just walking past can disrupt the melt pool and flame. This tunnels the wax down the side of the wick, making it harder to light evenly next time. Protect candles from drafts by lighting them in enclosed areas or using candle holders.

Choosing Wicks

When choosing wicks, there are a few key factors to consider for optimal candle performance. The main considerations are scent throw, minimizing smoke, durability, and sustainability.

For strong scent throw, you’ll want to choose a wick that encourages a full melt pool without getting too hot. Larger diameter wicks typically promote scent throw in larger candles. Testing different wick sizes to find the right balance for your specific wax and fragrance is key. Refer to a wick guide for recommendations based on your candle specifications.

To minimize smoke, select wicks made of materials like cotton that curl and retain their shape when burned. Wooden or paper wicks tend to create more smoke. Properly pre-waxing wicks before use also cuts down on smoking.

For durability, look for wicks with braided or knitted strands versus twisted strands which can loosen over time. Coreless wicks and those with zinc or tin reinforcements tend to be most durable.

When sustainability is a priority, look for natural fiber wicks like cotton, hemp, or beeswax. Some manufacturers also make eco-friendly paper and wooden wicks. Or choose longer lasting metal-core wicks to reduce waste.

Conclusion

In summary, the safest food safe wick options are cotton, wooden, paper, and eco-friendly wicks. Cotton and wooden wicks tend to be the most popular choices as they burn cleanly and don’t release any harmful chemicals. Paper wicks can also work well, but may not last as long. Eco-friendly wicks made from natural fibers like hemp and beeswax are a great option too.

Zinc core wicks may not always be food safe, so they require caution and research to ensure you choose a brand that is certified for food use. In general, you’ll want to avoid any wick with a metal core unless it is specifically designed as food safe.

When working with any wick, proper maintenance like trimming the wick as needed is important. But overall, cotton, wood, paper, and natural fiber wicks are your best bet for ensuring safety when making edible candles or wax projects.
