3 Ingenious Ways to Reuse Tuna Cans at Home

Attach the wick to the center of the bottom of the can using a candle wick sticker, wick tab, or another attachment method intended for candle making.

Avoid relying on ordinary craft glue in an area that may become warm during candle use unless the product is specifically appropriate for the temperatures involved.

The wick should remain upright and centered.

Step 3: Melt the Wax Safely
Follow the instructions provided with your chosen candle wax.

Many candle makers use a double-boiler method rather than placing wax directly over intense heat.

Never leave melting wax unattended.

Keep open flames away from melted wax and work in a stable, uncluttered area.

Step 4: Add Fragrance If Desired
If you want a scented candle, add candle-safe fragrance at the temperature and concentration recommended for your particular wax.

Using too much fragrance does not necessarily produce a better candle and can interfere with how the wax burns.

For a simple project, leaving the candle unscented is perfectly fine.

Step 5: Pour the Wax
Place the prepared tuna can on a heat-resistant, level surface.

Carefully pour the melted wax into the container without filling it completely to the rim.

Use a wick-centering bar, skewer, or similar tool positioned across the top to keep the wick upright while the wax cools.

Step 6: Allow the Candle to Set
Leave the candle undisturbed until the wax has fully cooled and hardened.

Do not move it unnecessarily while the surface is setting because this can create uneven texture.

Depending on the wax, additional curing time may be recommended before the first burn.

Trim the Wick Before Lighting
Before using the candle, trim the wick according to the recommendations for your wick and wax type.

An excessively long wick can create an unnecessarily large flame and more soot.

Keep the candle on a stable, heat-resistant surface while burning.

Important Candle Safety
Never leave a burning candle unattended.

Keep it away from curtains, paper, dried plants, clothing, drafts, children, and pets.

Do not burn the candle all the way to the very bottom of the container. Metal containers can become hot during use.
