How long do I burn my candles for?

Candles should be burned for no more than 4 hours at a time. Exceeding this recommended burn time can cause the glass container to overheat, potentially weakening or even cracking the glass. Burning a candle too long can also lead to wick "mushrooming"—a buildup at the wick's tip that causes the flame to burn hotter than normal.

To ensure safety, never leave a burning candle unattended, and always place it on a heat-resistant surface.
