Common Causes of a Candle Not Staying Lit
Several factors can contribute to a candle failing to stay lit, often related to the wick, wax, or environmental conditions. Understanding these causes helps in troubleshooting and maintaining a steady flame.
The wick plays a crucial role in how a candle burns. If the wick is too short, it will struggle to draw enough wax to fuel the flame. Conversely, a wick that is too long may produce an unstable flame that flickers or goes out. Additionally, a wick made from low-quality materials or one that is improperly trimmed can hinder consistent burning.
Wax composition and quality also impact candle performance. Some waxes contain additives or fragrances that can alter burning characteristics, causing the flame to sputter or extinguish. Impurities in the wax or uneven distribution of fragrance oils may lead to inconsistent melting and flame instability.
Environmental factors such as drafts, humidity, and airflow can cause a candle to flicker or go out. Even minor air movement can disturb the flame, especially if the candle is placed near windows, fans, or vents. High humidity can affect the wick’s ability to absorb wax, while drafts can cool the flame below its ignition point.
How Wick Size and Material Affect Candle Performance
Choosing the correct wick size and material is essential for a candle to maintain a steady flame. The wick must be proportionate to the candle’s diameter and wax type to ensure proper fuel delivery.
Wick Size: A wick that is too small will not draw enough wax, causing the flame to be weak and prone to extinguishing. An overly large wick creates an excessively tall flame, leading to soot and rapid consumption of wax.
Wick Material: Common wick materials include cotton, wood, and hemp. Cotton wicks are flexible and widely used, while wooden wicks provide a unique crackling sound but require specific wax types and candle sizes for optimal performance.

Eco-friendly candles, beeswax blends
Proper wick trimming is equally important; keeping the wick trimmed to about 1/4 inch before each lighting helps prevent soot buildup and promotes a consistent flame height.
Environmental Factors That Influence Candle Burning
The environment surrounding a candle significantly affects its ability to stay lit. Recognizing and adjusting for these factors can improve candle performance.
Airflow and Drafts: Even subtle air movement can cause a flame to flicker or extinguish. Placing candles away from open windows, ceiling fans, or vents helps maintain a stable flame.
Humidity: High humidity can saturate the wick and wax, making ignition more difficult and causing the flame to die out.
Temperature: Extremely cold temperatures can harden the wax, inhibiting the wick’s absorption of fuel, while excessive heat may cause the candle to melt unevenly.
Surface Stability: Placing a candle on an uneven or unstable surface can lead to inconsistent burning or accidental tipping.
To optimize burning conditions, consider these practical tips:
Keep candles in draft-free areas.
Avoid lighting candles in humid rooms such as bathrooms.
Maintain a stable room temperature, ideally between 65°F and 75°F.
Use heat-resistant and level candle holders to ensure stability.
Wax Quality and Composition Effects on Candle Flame
The type and quality of wax directly influence how a candle burns. Various waxes have distinct melting points, hardness, and fragrance-holding capacities, all impacting flame stability.
Paraffin Wax: Common and inexpensive, paraffin burns brightly but can produce soot if the wick is too large or untrimmed.
Soy Wax: A natural option that burns slower and cleaner but may require a specific wick type for optimal performance.
Beeswax: Known for a naturally sweet aroma and long burn time, beeswax candles typically produce a strong, steady flame.
Blended Waxes: Many candles use blends to balance burn time, scent throw, and appearance, but improper blends may cause tunneling or flame instability.
Impurities or excessive fragrance load can disrupt the wax’s melting pool, causing the wick to struggle or extinguish. Ensuring high-quality wax and appropriate fragrance percentages (typically below 10%) helps maintain a consistent flame.
