The mixture of these components determines the wax type. With thick candles occasionally “wall parts” remain because they are not heated enough by the flame.Ĭandle wax consists of a mixture of saturated and unsaturated long-chain hydrocarbons, acids, alcohols, and esters. The larger wicks can be expected to yield 5 to 7 hours per 28 g of wax used. Larger candles with larger wicks consume wax at a faster rate.Smaller candles with smaller wicks will burn at a rate of 7 to 9 hours per 28 g of wax used.How long does it take for a candle to burn down? The actual combustion reaction preferably starts in a zone of the flame above the wick. Here it also mixes with the gaseous fuel. In addition, colder air flows into the lower part of the flame through convection. The hot gas rises and mixes with the ambient air through diffusion. Here it evaporates due to the high flame temperature. The mixture of fuel and oxygen occures by convection and diffusion: The liquid fuel rises by capillary forces in the wick. By diffusion flame, it is meant that the fuel (here the candle wax in the form of various hydrocarbons) and the oxygen (from the air) required for the combustion are brought separately to the reaction zone (here the wick). To learn more about safe candle use, visit NCA’s Fire Safety & Candles page.Candle flames are considered laminar diffusion flames. If you enjoy fragranced candles, then use and replace them often to avoid deterioration in appearance and performance. Highly fragrant candles have a life span of 6 to 12 months, depending on the scent. Store candles in a cool, dark and dry place with the lid on to keep them clean of dust and debris, and to help protect the wax and fragrance. Moving air can disturb the flame, resulting in those pesky black marks on the glass. When burning a candle, avoid proximity to fans, air conditioners, open windows, or crowded areas with people walking back and forth. In general, it is recommended that candles do not burn for longer than four hours and cool for at least two hours before relighting. Avoid this by always following the manufacturer’s instructions. Plus, your candle will start to smoke and release soot. If a candle is not burned for long enough to allow the wax to liquefy or to melt from edge to edge of the container, it will create a “memory ring.” Once a candle has a “memory ring,” it will continue to tunnel for the life of the candle.ĭon’t keep candles burning for longer than indicated on the manufacturer’s instructions.īurning a candle for too long will cause carbon to collect on the wick, leading it to “mushroom.” The wick will then become unstable and produce a dangerously large flame. For example, a candle that is 2 inches across should burn for 2 hours. Candles should burn one hour for every 1 inch in diameter of the actual candle size. Just like the first cut is the deepest, that first burn is the most important. Your candles will burn up to 25% longer if you trim the wick every couple of hours. Trimming wicks will help prolong the life of your candle. Wicks that are left long or crooked can cause uneven burning, dripping, flaring and sooting. Too much fuel can cause the flame to unexpectedly flare up or even start a small fire near the candle flame. Any debris will add more fuel to the candle than it’s designed to handle.

Extend the life of your favorite candles, prevent unsightly soot and tunneling, and burn candles like a pro by following these simple tips: Always trim the wick and check for debris.īefore you light a candle, always trim the wick to ¼ inch and remove any debris left in the wax pool such as wick trimmings or matches. Luckily, so is following proper candle care and safety guidelines.
