What Candle Wicks Are Made Of: Materials, Types, Safety, and How They Affect Burn Quality
When most people pick up a candle, they focus on the scent, the color of the wax, or the aesthetic of the jar. But there’s one component that matters more than almost anything else when it comes to how a candle burns, how long it lasts, and how powerful the fragrance throw is: the wick.
The wick is the quiet engine of a candle. It looks simple — just a thin strip of wood or braided cotton — but it is a carefully engineered tool designed to draw liquid wax toward the flame in a controlled, safe, and efficient way. A high-quality wick can completely transform the burn quality of a candle, while a poor wick can lead to tunneling, uneven melting, soot, smoking, overheating, or even the candle extinguishing itself.
In this extended guide, you’ll learn everything about what candle wicks are made from, how they work, why the materials matter, how wick quality affects fragrance throw, and how to choose candles with the best wicks for a clean, luxurious burn every time.
Whether you’re a candle enthusiast, a new shopper trying to understand the difference between brands, or someone curious about what goes into quality home fragrances, this guide will walk you through every detail.
1. Why the Wick Matters More Than Most People Realize
The wick is the heart of the candle. While wax type and fragrance oil blend matter for performance, the wick is the component that determines how:
-
Evenly the candle burns
-
Cleanly the wax melts
-
Strongly the scent travels
-
Much smoke or soot appears
-
Long the burn time lasts
-
Safe the flame is
-
Hot or cool the candle burns
A perfectly chosen wick creates the kind of candle everyone wants: a smooth melt pool, a steady flame, and a bold scent that fills the room. A poorly chosen wick ruins the experience: it can tunnel, flicker, smoke, burn too weak or too aggressively, or fail to stay lit at all.
That’s why premium brands spend months testing wicks, wax compositions, vessels, and fragrance loads until they find the perfect pairing. Wick material plays a huge role in that testing.
2. The Core Materials Candle Wicks Are Made From
Candle wicks are made from a combination of natural fibers, wood, specialty cores, and sometimes paper or filament reinforcements. Each material creates a different burning behavior, flame strength, and aesthetic.
The four primary wick types include:
-
Cotton wicks
-
Wooden wicks
-
Paper-core wicks
-
Cotton-core or fiber-core wicks
Below, you’ll find a full breakdown of each type, what they’re made from, how they burn, and why certain candles use one material over another.
3. Cotton Wicks: The Most Common and Most Trusted Wick Material
Cotton is the most widely used wick material in the candle industry and the standard for high-quality home fragrances.
What Cotton Wicks Are Made Of
Cotton wicks are typically constructed from:
-
100% natural cotton fibers
-
Braided, plaited, or knitted strands
-
Sometimes intertwined with thin paper filaments
-
Often coated in natural wax for rigidity
Because cotton is soft, the strands are braided tightly so the wick can stand straight and burn with consistent strength.
Features of Cotton Wicks
Cotton wicks are popular because they burn:
-
Clean
-
Predictably
-
Evenly
-
With minimal soot
-
Without heavy mushrooming
They are also incredibly compatible with multiple wax types, including soy blends, paraffin, coconut wax, and hybrid wax mixtures.
Why Premium Candle Brands Use Cotton
-
Long, stable flame
-
Good melt pool formation
-
Strong fragrance release
-
Non-toxic fiber
-
No harsh additives
-
Reliable performance
Cotton wicks are especially ideal for multi-wick candles, such as 3-wick jars, because they maintain an even burn across a large surface area.
4. Wooden Wicks: The Modern, Crackling Alternative
Wooden wicks have exploded in popularity in recent years because they feel warm, luxurious, and modern. They give candles a more refined and artisanal feel.
What Wooden Wicks Are Made Of
Most wooden wicks are crafted from:
-
Natural hardwood
-
FSC-certified wood
-
Single-layer or dual-layer wood strips
-
Sometimes curled or tube-shaped wood
Many wooden wicks are sourced from sustainable lumber to ensure consistent burning quality.
Why Wooden Wicks Stand Out
Wooden wicks provide:
-
A soft, soothing crackling sound (like a mini fireplace)
-
A wide flame with robust scent throw
-
An elegant and premium look
-
Cleaner burning with less mushrooming
They are especially effective in soy-coconut blends, which complement the flame width wooden wicks naturally produce.
Types of Wooden Wicks
-
Straight single-ply (most common)
-
Dual wooden wicks (for stronger flames)
-
Tube wicks (hollow inside for airflow)
-
Crosswood wicks (layered for more crackle)
Their structure influences flame size, melt pool consistency, and heat distribution.
5. Paper-Core Wicks: The Reinforced Braided Option
Paper-core wicks feature a cotton exterior with a paper filament running through the center.
What They Are Made Of
-
Braided cotton
-
A tightly wound paper core
The paper core gives the wick shape and rigidity.
Why They Are Used
Paper-core wicks are ideal for:
-
Softer waxes that need more structure
-
Candles that require a hotter, stronger flame
-
Large jars that need deeper melt pools
-
Multi-wick candles
Because they burn hotter than pure cotton, they help prevent tunneling in waxes that require more heat.
6. Cotton-Core or Fiber-Core Wicks
These wicks use a combination of:
-
Natural cotton exterior
-
A strong cotton filament interior
They are similar to paper-core, but the core is also made of cotton.
Why Candle Makers Use Them
Cotton-core wicks are known for:
-
Maintaining shape in deep wax pools
-
Creating taller, more powerful flames
-
Burning well in harder wax blends
-
Enhancing throw in large candles
They’re ideal for candles that need structure without relying on paper or metal cores.
7. Metal Wicks (No Longer Common)
Years ago, some candles used metal-core wicks, especially zinc.
These were made from:
-
Braided cotton
-
A zinc filament
Metal cores were once used for rigidity, but many premium brands now avoid them because natural alternatives perform better.
Lead-core wicks were banned in the U.S. in 2003 for safety reasons.
Today, metal-core wicks are rare and mostly obsolete.
8. Wick Coatings: What Wicks Are Treated With
After a wick is braided or cut, it’s usually coated lightly with wax.
Common coating options include:
-
Soy wax
-
Beeswax
-
Paraffin wax
-
Natural stabilizers
The coating helps the wick stand straight during production and ensures it catches flame easily when lit.
Premium brands avoid harmful chemicals or dyes in wick coatings.
9. How Wick Material Affects a Candle’s Burn
The wick determines the entire burn experience. Here’s how wick material influences performance:
Flame Size
-
Cotton = steady, medium flame
-
Wood = wider flame
-
Core wicks = taller, hotter flame
Melt Pool Formation
A wick that burns too cool creates tunneling.
One that burns too hot overheats the jar.
Material choice helps balance both issues.
Fragrance Throw
More heat = stronger scent
Less heat = softer scent
Wood and multi-wick cotton candles usually throw fragrance fastest.
Safety + Stability
Good wick materials maintain posture and prevent drowning.
Soot Production
Natural materials such as cotton and wood produce minimal soot, especially when trimmed to ¼ inch.
10. How to Tell if a Candle Has a High-Quality Wick
You can judge wick quality with simple observations:
1. The flame stays steady.
A flickering flame typically means the wick and wax blend aren't balanced.
2. The candle forms a full melt pool.
You should see liquid wax reach the edges within 1–2 hours.
3. There is minimal soot.
High-quality wicks burn cleaner.
4. The jar stays safe and stable.
A controlled flame prevents overheating.
5. The wick doesn’t mushroom heavily.
A little is normal; large mushroom heads indicate poor wick pairing.
6. The scent throw is strong and even.
The right wick helps fragrance bloom. Brands that invest in wick testing prioritize all of these outcomes.

11. Why Wick Material Matters for Fragrance Lovers
The wick is responsible for pulling melted wax — the fuel — to the flame. More heat means faster melting, which means more fragrance oil evaporates into the air.
Cotton wicks:
-
Balanced throw
-
Clean burn
-
Ideal for everyday use
Wooden wicks:
-
Wide melt pool
-
Powerful fragrance output
-
Cozy ambiance
Multi-wick candles:
-
Even faster scent release
-
Ideal for large rooms
If you want your home to smell stronger, faster, or more evenly, wick material matters more than almost anything else.
12. Clean-Burning Candle Wicks: What to Look For
Look for candles that clearly state:
-
Wick type (cotton, wood, etc.)
-
Lead-free + zinc-free wicks
-
Natural fibers
-
Tested wicking
-
Sustainable materials
Premium brands take wick transparency seriously because quality components earn long-term trust from customers.
13. How Premium Candle Brands (Like Affinati) Select Wick Materials
High-end candle companies don’t pick a wick based on guesswork. They perform:
-
Burn tests
-
Flame-height tests
-
Soot + smoke tests
-
Melt pool evaluations
-
Hot throw + cold throw measurements
-
Vessel temperature checks
A single candle may be tested with six to twelve different wick types before the perfect one is chosen.
Brands like Affinati use:
-
Premium cotton wicks in 17 oz 3-Wick Candles
-
Crackling wooden wicks in their wooden-wick lines
-
Lead-free, zinc-free fibers
-

This ensures every candle burns evenly, cleanly, and with a bold scent that fills your space.
14. Final Thoughts: The Wick Is the Soul of a Candle
Even though a wick may look simple, it is the most important part of a candle’s performance. Wick materials determine:
-
How clean a candle burns
-
How long it lasts
-
How powerful the fragrance is
-
How safe the flame is
-
How enjoyable the experience feels
Cotton wicks are the universal clean-burn standard.
Wooden wicks elevate ambiance with crackle and warmth.
Paper-core and cotton-core wicks offer structure and heat for larger vessels.
No matter what type of candle you prefer, choosing one with a premium wick ensures better fragrance, better value, and a more luxurious experience in your home.
