Why Do Some Candles Burn Unevenly? Common Candle Problems and Fixes

A beautifully burning candle sets the perfect ambiance, but sometimes things don’t go as planned. If you’ve ever noticed your candle burning unevenly, tunneling, or producing excessive soot, don’t worry—you’re not alone. Here’s why some candles burn unevenly and how to fix common candle problems for a longer, cleaner burn.

1. What Causes Uneven Burning?

Uneven burning, also known as tunneling, occurs when a candle burns down the center, leaving excess wax on the sides. This can happen due to several factors:

  • First Burn Memory: Candles have a memory, meaning the first burn sets the foundation. If a candle isn’t allowed to melt evenly across the surface, it will continue to burn in a tunnel.

  • Drafts & Airflow: Placing a candle near windows, fans, or air vents can cause an uneven burn due to inconsistent heat distribution.

  • Wick Size & Type: A wick that’s too small may not generate enough heat to fully melt the wax, while a wick that’s too large can cause excess flickering and uneven melting.

2. How to Prevent and Fix Tunneling

  • Burn to the Edge: Allow the candle to burn until the melted wax reaches the edges of the container, especially on the first burn (this can take 1-3 hours, depending on the size of the candle).

  • Aluminum Foil Trick: If tunneling has already started, wrapping the candle’s top edge in aluminum foil (leaving an opening at the center) can help reflect heat and even out the wax pool.

  • Avoid Short Burns: Extinguishing a candle too soon can prevent the wax from fully melting, contributing to tunneling.

3. Wick-Related Issues & Fixes

  • Mushrooming Wick: If your wick forms a mushroom-like tip, it’s due to carbon buildup. Trim the wick to 1/4 inch before each burn to prevent excessive soot and ensure a steady flame.

  • Wick Drowning: If a wick gets too short and struggles to stay lit, pour out excess wax or use a wick dipper to reposition the wax around the wick.

  • Flickering Flame: A constantly flickering flame is usually caused by a draft or an improperly sized wick. Move your candle away from air currents and ensure the wick is properly trimmed.

4. How to Reduce Soot and Smoke

  • Trim Your Wick: Always keep the wick at about 1/4 inch to minimize excessive soot.

  • Burn in a Stable Environment: Avoid placing candles near drafts or in confined spaces with little airflow.

  • Use High-Quality Wax: Cheap, low-quality wax can produce more soot. Opt for clean-burning soy wax candles, like those from Haus of Flame Candle Co.

5. Storage and Care Tips for a Longer-Lasting Candle

  • Keep Candles Covered: Dust and debris can affect the quality of the burn. Store candles with a lid or in a dust-free environment.

  • Burn in Proper Intervals: Let candles burn for at least 1-2 hours but avoid burning for more than 4 hours at a time to prevent overheating.

  • Use a Snuffer: Blowing out a candle can create excess smoke. Instead, use a candle snuffer for a cleaner extinguish.
