How to Get the Most Burn Time From Your Aromatherapy Candle Jar

The rated burn time printed on a candle's packaging assumes it's burned correctly - and a bad first light can permanently shrink how much use you actually get out of a jar. This sub-blog is part of our Aromatherapy Candles for Home Wellness Guide and covers how to avoid that.

Get the First Burn Right

The single biggest factor in total candle life is the first burn. Let the wax melt pool reach all the way to the edges of the jar on the very first light - stopping too early creates a phenomenon called "tunnelling," where the wax in the centre burns down while wax at the edges is left untouched on every future burn, permanently wasting a portion of the jar.

Trim the Wick Before Each Light

Trim the candle wick to about 5mm before each burn. A wick that's too long burns hotter and faster, produces more soot, and shortens the candle's overall lifespan compared to a properly trimmed one.

Avoid Short Burns

Burning a candle for less than an hour at a time repeatedly worsens tunnelling and prevents the fragrance from fully developing in the room. Aim for at least 1-2 hours per session where possible, allowing the full wax pool to form.

Keep It Away From Drafts

●        Avoid placing candles directly in front of fans, open windows or air conditioning vents

●        Drafts cause uneven burning and can make a candle burn faster than its rated time

●        A stable, draft-free spot also keeps the flame steadier, which improves how evenly the fragrance disperses

Store Between Uses

Keep the lid on between burns to protect the fragrance from evaporating and to keep dust out of the wax. Once you've got the burn technique right, our guide on building a candle ritual covers how to make the most of that time rather than just watching it burn.

FAQs

Q1. Why does my aromatherapy candle burn unevenly?

This is usually caused by not letting the wax pool reach the edges on the first burn, known as tunnelling, which then repeats on every future use.

Q2. How often should I trim a candle wick?

Before every burn - trim to about 5mm to avoid excess soot, uneven burning, and a shortened overall candle lifespan.

Q3. Is it bad to burn a candle for a short time?

Repeated short burns under an hour can worsen tunnelling and prevent the fragrance from fully developing, so longer sessions of 1-2 hours generally give better results.

Q4. Should I keep the lid on an aromatherapy candle when not in use?

Yes, keeping the lid on between burns helps protect the fragrance from evaporating and keeps dust out of the wax.
