Wick centering tool

A wick centering tool is a small bar, clip, or clothespin style device placed across the top of a candle container to hold the wick upright and centered while the poured wax cools and hardens. Without one, a wick can drift toward one side of the container as the wax sets, especially in wider jars.

Keeping the wick centered matters for both appearance and burn performance. An off-center wick tends to create an uneven melt pool, burn closer to one side of the glass, and can raise the risk of the flame getting too close to the container wall as the candle burns down. It also looks noticeably off in a finished candle, which matters for anything made to sell.

Reusable wick centering tools that adjust to different jar widths are convenient across a range of container sizes, though many makers start with improvised options like clothespins or bamboo skewers taped across the rim. A common mistake is removing the centering tool too soon, before the wax has fully set, which lets the wick shift again before it is locked in place.
