Question 1

How long does a candle burn?

Accepted Answer

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. Wood wicks burn slightly faster at 6 to 7 hours per ounce. The calculator above tunes this per wick series and wax type.

Question 2

How long do candles last?

Accepted Answer

Burn time depends on wax weight and wick consumption rate. As a buyer's rule of thumb: 4 oz lasts 25 to 35 hours, 8 oz lasts 50 to 70 hours, 12 oz lasts 80 to 100 hours, 16 oz lasts 110 to 140 hours. Soy lasts longer than paraffin at the same weight because soy burns cooler.

Question 3

How long does a 10 oz soy candle burn?

Accepted Answer

A 10 oz soy candle gives roughly 65 to 80 hours with a correctly sized cotton wick (CD-14 or ECO-14 in a 7.5 to 8 cm jar). Wood wicks bring it down to 55 to 65 hours but add the crackle.

Question 4

How long does a 12 oz soy candle burn?

Accepted Answer

A 12 oz soy candle gives roughly 80 to 100 hours with a single CD-18 or CD-20 cotton wick. If you've stepped up to two CD-10s for an even melt pool, expect 70 to 85 hours because two flames consume fuel faster.

Question 5

How long does a 16 oz soy candle burn?

Accepted Answer

A 16 oz soy candle gives roughly 110 to 140 hours single-wick, or 90 to 115 hours as a 2-wick. Three-wick layouts (used above 10 cm diameter) typically land at 70 to 95 hours because three flames burn through the wax faster.

Question 6

How long does a tealight burn?

Accepted Answer

A standard 14 g tealight burns for 3 to 5 hours. The metal cup stays hot for 30 minutes after the flame goes out, so never leave a tealight unattended or place it on a heat-sensitive surface like wood or plastic.

Question 7

How long does a taper candle burn?

Accepted Answer

Tapers burn at roughly 1 to 1.5 hours per inch of height. A 10 inch dinner taper lasts 10 to 12 hours. Beeswax tapers burn slightly longer (1.5 to 2 hours per inch) because beeswax has a higher melt point.

Question 8

How long should I burn a candle the first time?

Accepted Answer

Long enough to melt the wax all the way to the jar wall, which is usually 2 to 3 hours for an 8 to 12 oz jar. This sets the candle's memory and prevents tunneling on every future burn. Snuff (don't blow), let it cool fully, then trim the wick before relighting.

Question 9

How long can you burn a candle at one time?

Accepted Answer

Maximum 3 to 4 hours per session. After that, carbon builds up on the wick (mushrooming), the flame gets taller, the glass overheats, and soot starts depositing on the rim. Snuff, let it cool for at least 2 hours, trim the wick to a quarter inch, then relight.

Question 10

How do I make my candle burn longer?

Accepted Answer

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. A drafty room cuts burn time by 20 to 30 percent and roughens the melt pool.
