People spend a lot of time thinking about candle scents and almost no time thinking about the wick. That's understandable - the scent is why you bought the candle. But the wick determines whether you actually get to enjoy that scent. It controls how the candle burns, how the flame behaves, how evenly the wax melts, and how effectively the fragrance fills a room.
Different wick materials perform differently. Here's what you need to know about each one.
Cotton Wicks: The Standard for a Reason
Cotton wicks are the most common type in quality candles, and every brand we carry - P.F. Candle Co., Dilo, Broken Top Candle Co., Candlefy, and Studio Stockhome - uses them. There's a reason for that consistency.
A cotton wick is a braided bundle of cotton fibers, and the braid pattern matters more than most people think. The tightness and direction of the braid control how quickly the wick draws up liquid wax through capillary action. A tighter braid pulls wax more slowly, creating a smaller flame. A looser braid draws more wax and creates a larger flame.
What cotton does well: Consistent burn. Cotton wicks produce a steady, upright flame that's easy to manage. They work well with soy wax, which is why you see them paired together so often. The flame stays centered, the melt pool spreads evenly, and the scent throw is reliable.
What to watch for: Cotton wicks do mushroom over time - that carbon buildup at the tip that looks like a tiny mushroom cap. It's normal, not a defect. Just trim the wick to a quarter inch before each burn and the mushrooming resets. Our wick science post explains why this happens and how to handle it.
Cotton wicks also come in flat-braided and square-braided varieties. Flat braids tend to curl slightly as they burn, which is actually an advantage - the curl positions the tip of the wick in the hottest part of the flame, promoting more complete combustion. Most of the candles on our shelves use flat-braided cotton wicks.
Wood Wicks: The Aesthetic Choice
Wood wicks have become increasingly popular in the last few years, and it's mostly because of one thing: the crackle. A wood wick candle sounds like a miniature fireplace. That soft, popping sound is genuinely pleasant and adds an atmospheric quality that cotton wicks can't replicate.
A wood wick is a thin strip of wood (usually cherry, maple, or birch) that channels liquid wax upward through the grain instead of through fiber capillary action.
What wood does well: Ambiance. The wider, shorter flame creates a horizontal flicker rather than a tall point. Combined with the crackling sound, it's a sensory experience that goes beyond scent. Wood wicks also tend to produce a wider melt pool, which can improve scent throw - the broader flame heats more wax surface area at once.
What to watch for: Wood wicks are pickier. They're harder to light (hold the flame for 10-15 seconds), and they need more maintenance - you have to break off the charred wood before relighting. The sweet spot for wick length is about 1/8 to 3/16 of an inch, shorter than cotton's quarter inch. They also work best with softer waxes like soy and coconut blends.
Zinc-Core and Metal-Core Wicks: Know What to Avoid
You won't find zinc-core wicks in any candle at our shop, but they're common in cheap candles at big-box stores. These wicks have a thin metal wire through the center of the cotton braid to keep the wick standing upright in wide-mouth jars.
The tradeoff: zinc-core wicks burn hotter than cotton, which means faster wax consumption and shorter candle life. The hotter burn can also degrade fragrance molecules, changing the smell. Lead-core wicks were banned in the US in 2003, but zinc and tin cores are still everywhere in budget candles. They're not dangerous - just less effective than a properly sized cotton wick.
If you pick up a candle and the wick feels stiff with a wire inside, that's a metal core. Not a dealbreaker, but a sign the manufacturer is prioritizing convenience over performance.
Hemp Wicks: The Natural Alternative
Hemp wicks are less common in finished candles but popular among DIY makers. They burn slowly and at a lower temperature than cotton - slightly less fragrance throw but longer burn time per ounce of wax.
The tradeoff is a less stable flame and a faint characteristic smell when burning. You're more likely to find hemp wicks at farmers' markets than from established brands. A niche choice, but a legitimate one.
How Wick Choice Affects Scent Throw
This is the part most people care about: does the wick affect how much scent fills the room?
Yes. Significantly.
A wick that burns too cool won't melt enough wax to release fragrance oil. A wick that burns too hot vaporizes the oil so quickly that the initial burst is strong but the candle runs through its scent faster.
This is why candle makers test extensively. The brands on our shelves have already done this engineering - they test multiple wick sizes for each candle to find the one that creates a full melt pool, releases fragrance consistently, and burns cleanly. If you've ever wondered why a budget candle smells weak despite listing a high fragrance load, the wick is almost certainly the issue.
Which Brands Use Which
Here's a quick breakdown of what's on our shelves:
- P.F. Candle Co. - Cotton wicks in soy wax. Reliable, steady burn with strong scent throw. $24 for 7.2oz.
- Dilo - Cotton wicks in 100% soy wax. The elsewhere collection ($32) uses a wick gauge tuned for their 8.5oz jars. The amber glass line ($14) uses a narrower wick for the smaller vessel.
- Broken Top Candle Co. - Cotton core wicks in soy wax. Consistent performance across their wide scent range. $26 for 9oz.
- Candlefy - Cotton wicks in a soy blend. Good middle-ground performance. $25 for 8oz.
- Studio Stockhome - Cotton wicks in a soy, coconut, and beeswax tri-blend. The beeswax in the mix means a slightly firmer wax that requires a carefully calibrated wick. $38 for 8oz.
Every one of these is a cotton wick in soy-based wax. That's not a coincidence - it's the combination that produces the best balance of burn time, scent throw, and clean performance.
What This Means for You
You don't need to become a wick expert to enjoy a candle. But understanding what's in your candle helps explain why some candles perform better than others, and why making a candle last longer starts with how the wick is treated.
The short version: trim it, give it a proper first burn, and buy candles from brands that test their wicks. Everything else is details.
