Why Is My Candle Tunneling — and How to Make It Last Longer
Nothing is more frustrating than a candle that melts straight down the center, leaving thick walls of hard, wasted wax around the edges. Known as candle tunneling, this common issue is easily preventable and simple to fix.

What Causes Candle Tunneling?

Candle wax has a "memory." When you light a candle for the very first time, the melt pool established during that initial burn sets the diameter for all future burns. If the wax is extinguished before melting fully to the container edges, the candle will continue tunneling downward in that same narrow channel.

The Golden Rule: The First Burn

Always allow your candle to burn for at least 2 to 3 hours during its first lighting — or until the liquid wax pool reaches all the way to the outer glass walls. This establishes an even burn memory for the entire life of the candle.

How to Fix Existing Tunneling: The Foil Method

If your candle has already tunneled, wrap a piece of aluminum foil around the top rim of the jar like a dome, leaving a small opening in the center for the flame. The trapped heat will gently melt the high wax walls down into the pool, resetting the surface completely flat.
