How long does a candle burn?

A clean-burning soy candle gives roughly 7 to 9 hours per ounce of wax. An 8 oz candle should last 50 to 70 hours. Cotton wicks burn slower than wood; wood wicks are typically 6 to 7 hours per ounce.

How do I make my candle burn longer?

Trim the wick to a quarter inch before every burn, never burn for less than two hours (to avoid tunneling) or more than four hours per session, and keep the candle away from drafts.
