What Determines a Candle's Burn Time?
Burn time refers to the total amount of time a candle can burn before the wax is fully consumed. For soy candles, several variables affect how long they last:
1. Wax Type
Soy wax burns slower than paraffin, which is one reason people choose soy for long-lasting candles. It also melts at a lower temperature, making it ideal for clean, even burns.
2. Wick Type and Size
Wicks made from cotton or wood are typically used in soy candles. The thickness and length of the wick determine how hot the flame gets, which affects how quickly the wax melts.
3. Candle Size
A larger candle naturally contains more wax, which equates to a longer burn. For example:
-
4 oz soy candle: ~20–25 hours
-
8 oz soy candle: ~40–50 hours
-
12 oz soy candle: ~60–80 hours
-
3-wick soy candle: ~60–90+ hours
Many users looking for value will search for best soy candles with long burn time or slow burning soy wax candles.
4. Container Shape
Wide, shallow containers can cause wax to melt too quickly, while taller containers with narrower diameters typically burn slower and more evenly.
5. Fragrance Load and Additives
Heavily scented candles may burn slightly faster, especially if additives or synthetic oils are used. High-quality soy candles use essential oils or phthalate-free fragrances that are optimized for performance without sacrificing burn time.
Average Burn Time of Soy Candles
So, how long does a soy candle burn compared to others? On average, soy candles burn about 7–9 hours per ounce of wax under ideal conditions.
| Candle Size | Estimated Burn Time |
|---|---|
| 4 oz | 20–25 hours |
| 6 oz | 30–40 hours |
| 8 oz | 40–50 hours |
| 12 oz | 60–80 hours |
| 3-wick (14+ oz) | 70–90+ hours |
That means if you're searching for a long burn time soy candle for daily use, an 8 oz jar could provide over a week of light if burned for 5–6 hours a day.
Soy vs Paraffin Candle Burn Time
One of the reasons soy is so popular is its longer burn time compared to paraffin. Paraffin burns hotter and faster, which means you go through candles more quickly.
| Wax Type | Burn Time | Soot Level | Scent Quality |
| Soy Wax | Slower (longer lasting) | Low | Clean, natural |
| Paraffin | Fast burning | High | Often synthetic |
Searches for "soy vs paraffin wax burn time" or "which candle wax lasts the longest" usually lead shoppers to discover the superior longevity of soy.
Why Soy Candles Burn Longer
Lower Melting Point
Soy wax has a lower melting point than paraffin, meaning it melts more gradually and evenly.
Cleaner Combustion
Because soy wax burns more cleanly, it produces a stable flame without excessive soot or flickering, which preserves wax and extends use.
Higher Efficiency
More of the wax in a soy candle is consumed during burning. This means less tunneling and less wasted wax.
These qualities appeal to people searching for eco-friendly candles with slow burn or best natural wax candles for long-lasting scent.
How to Maximize the Burn Time of a Soy Candle
If you want to get the most hours out of your soy candle, here are a few pro tips:
1. Trim the Wick
Always trim your wick to about 1/4 inch before each burn. This reduces the flame height, prevents mushrooming, and slows wax consumption.
2. Let It Pool
The first time you burn your candle, let the entire top layer of wax melt all the way to the edge. This helps prevent tunneling and ensures even future burns.
3. Avoid Drafts
Burning candles in drafty areas can lead to uneven burns and faster melt times. Keep your soy candle away from fans and windows.
4. Don’t Burn Too Long
While it’s tempting to keep a candle lit all night, burning for more than 3–4 hours at a time can overheat the wax and reduce total lifespan.
5. Use the Right Container
Thick glass jars or ceramic holders help regulate heat and ensure a stable flame, which is key for optimizing soy candle longevity.
