Choosing a candle can raise questions once you start reading the label. A 2019 explainer from the National Candle Association walks through several common product claims and the safety instructions that consumers should expect to see, offering context for shoppers who want to follow manufacturers' guidance.
Lead-Free Wick Claims
Many candles on the market are advertised as having a lead-free wick. According to the National Candle Association, that feature matters for consumer safety, but there is no practical difference between candles sold in the United States that carry the claim and those that do not. The reason is that lead wicks have been officially banned in the United States since 2003, and before the ban they were mainly found in inexpensive imported candles. Association members voluntarily agreed not to use lead wicks in 1974, the group notes, and have long backed efforts to eliminate them.
Hand-Poured Labels
Some manufacturers, particularly smaller brands, describe their products as hand-poured. In practice, the term means the melted wax is combined with any fragrance and poured into the candle vessel by hand. Hand-poured candles tend to be produced in smaller batches and may carry a more artisan feel. The association adds that regardless of the production method, all reputable candle makers follow rigid quality standards.
Understanding Burn Time
Burn time is the estimated period a candle will burn. Many variables affect it, including the wax type and fragrance load, but generally a larger candle will burn longer than a smaller one. Consumers are advised to follow the manufacturer's instructions and not exceed the recommended burning duration. In general, candles should not be burned for more than four hours at a time. Longer burns can allow carbon to collect on the wick, which may cause the flame to become too large and the candle to smoke. The association also recommends discarding a candle once about a half-inch of wax remains in the container.
Why Multi-Wick Candles Are Common
Candles with multiple wicks have grown popular as demand for larger candles has risen. Multiple wicks can help support a more even burn and prevent tunneling. Shoppers may want to avoid candles that are especially wide but have only a single wick, since one wick may not generate enough heat to melt the wax evenly across the surface. The association advises shoppers to judge wick count in relation to the diameter of the candle rather than treating more wicks as an automatic sign of quality.
Safety Labels to Look For
When shopping, the association cautions against buying a candle that has no safety label. Reputable manufacturers follow industry standards, and a missing label may indicate that other important fire-safety design guidelines have not been met.
The National Candle Association has played a leading role in developing industry standards set out in the ASTM F2058 Standard Specification for Candle Fire Safety Labeling. Under those standards, every candle should have a cautionary label or tag listing three key fire-safety rules, along with graphic safety symbols.
- Burn within sight: Keep an eye on all burning candles and extinguish them before leaving a room.
- Keep away from combustibles: Pay attention to surroundings and keep burning candles away from furniture, drapes, bedding, carpets, books, paper and other flammable objects.
- Keep away from children: Place candles up high and out of reach of children and pets.
The association points consumers to its Learn the Label page for more information about product safety. For shoppers, the recurring theme is that claims and cautions work together: a label that explains the wick, the expected burn time and the required safety rules gives a clearer picture of how a candle should be used. Labels for cotton wick candles can identify wick material, but the association’s central point is that construction claims do not replace the manufacturer’s safety instructions.
