CAUTION: Never add water or place liquids next to a candle. This is dangerous and can cause a fire or explosion.

In case of an emergency, please follow National Fire Extinguishing Practices for putting out fires i.e using an ABC fire extinguisher, baking soda etc.

Memory burn

The first time a candle is lit is called its "memory burn". This first impression sets the boundaries for how the candle will burn until the wick is gone.

Trim your wicks before each use to avoid soot and excessive mushrooming contaminating the wax.

Memory ring 

If a candle isn't burned long enough to melt all the way to the edges of the container, it will create a "memory ring". When the candle is lit again, the wax will only burn up to the last point it reached, creating a tunneling effect. This is because previously melted wax is softer and melts more easily than unmelted wax.

Muscle memory

If a candle is lit long enough the first time to pool evenly across the top, it will likely pool evenly in the same pattern each time it's lit after that.

Drafts can cause an unsteady flame resulting in an uneven burn. If drafts are unavoidable, periodically rotate the candle to counteract any uneven burning.
