Why Do Candles Tunnel? (And How to Fix It Properly)
Have you ever wondered why your favourite scents waste so much wax? This phenomenon occurs when a flame burns straight down the middle, leaving un-melted wax along the edges. Learning why candles tunnel helps you prevent it, enjoy longer burn times, and get the most from luxury scented candles like those from That Candle Company.
What Is a Tunnelled Candle and Why Does It Happen?
This issue occurs when a flame melts only the wax in the center, leaving thick walls of unused material. This problem shortens your total burn time and reduces your overall enjoyment. Fortunately, understanding the mechanics of a tunnelled candle helps you choose products engineered to burn edge-to-edge.
Main Reasons Why Candles Tunnel.
Several factors cause this to happen, and most are simple to understand and prevent.
1. Why the First Burn Is the Main Reason Candles Tunnel.
You often cause a “memory ring” by extinguishing a flame too early during the very first light. Luxury candles need enough time on the initial burn to melt the wax completely to the glass.
Therefore, for most jars, you should allow the first session to last for 2–4 hours. Stopping too soon “trains” the wax to stay narrow for the rest of its life.
2. Design Flaws That Explain Why Candles Tunnel.
Some products fail because their wax type, wick size, and container diameter do not match. If the wick is too small, the flame cannot generate enough heat to melt the full surface.
In contrast, That Candle Company hand-pours each batch with a precise balance of premium wick and wax to ensure a level surface.
How to Fix a Candle That Tunnels Successfully.
If your jar already shows signs of a “cave” forming in the center, you can restore it with these simple methods:
Using the Foil Method to Stop Candles That Tunnel.
Wrap aluminum foil around the top of the container, leaving a small opening above the flame. The foil reflects heat inward to melt the outer edges. Leave it for 30–60 minutes, then carefully remove the foil once the surface is liquid.
Using a Warmer to Reset Tunnelled Candles.
You can also soften hardened outer rings with a gentle electric candle warmer. This melts the entire surface at once, allowing the wax to reset to a flat, even state.
Preventative Steps: How to Stop Candles From Tunnelling Again.
- Allow a Full Melt Pool: Always let the liquid wax reach the glass edges before putting out the flame. A professional candle snuffer is the best way to put out the flame on your Luxury Candles out.
- Trim the Wick: Trim your wick to around 5mm before every use to ensure a steady, even heat source. Use a professional wick trimmer for perfect results.
- Choose Artisan Quality: High-quality, hand-poured candles from That Candle Company are specifically designed to avoid these issues.
