ECO 16 6" Pretabbed Cotton Candle Wicks
Choose a Variant

Product Update:
You may see some variation in the wax coating on the wick due to different coating processes. The variance of the wax coating on the wick has no impact on the burn of the candle.

About the ECO Series
ECO wick is constructed from natural flat cotton threads interwoven with paper threads that produce a rigid structure for easy pouring. The consistent flame and slight curl of ECO wicks work well with natural waxes and ensures an even burn.

ECO wicks are lead and zinc free.

For help choosing the right wick for your candle, visit our wick guide.

Conveniently secure your wicks with Wick Stickers (large) or Wick Stickers Pro.

I've learned that there has to be a certain amount of space from the wax to the top of the glassware, so the wick receives enough oxygen for combustion. When I don't leave enough space, the candle doesn't light well.

Great wicks!

Although I love these, I’m trying to find a more thicker wick. I have a 16oz straight jar and just looking to find the right size to limit the amount of wicks I have to use.

Please advised! Thank you!

Very good wicks

Excellent wicks. There is no one size fits all wick as the wick type and wick size really do depend upon the candle wax, fragrance, and container you are using. These wicks work out very well for my Freedom Soy candles and Freedom Soy/Paraffin candles in a 3-inch diameter glass jar. Occasionally, I need a different wick for different fragrances but most of my candles like these ECO-16 wicks. Wicks are very consistent and well made. They self trim very well with only a little bit of maintenance and they burn in 4 hour increments very well.

Not happy

I am testing the EC0-16 in a 3" diameter jar using GB-464 soy wax and 9% Caramelized Pralines and no dye, etc. First, it's hard getting this lit and I succeeded on the 2nd try. It burned fine the first 2.5 hours and the throw, although it was a bit too mild, was reasonably consistent and it achieved a full melt pool in about 2 1/2 hours, and then at exactly the three hour mark, the flame began drowning. Testing this against the CD-20 using the exact same formula, CD-20 definitely a far better choice.

Just okay

I agree with one of the users. It definitely works better for some scents versus others. I see tunneling with some of my candles… but not too bad. Eventually it’ll burn even towards the end. The diameter container I tried them in is about 3.3”.

Wick Scents

I like the wicks but it does better with certain scents I use. Also, it does well in certain containers. For example, 8 OZ. mason jars or 12 OZ. plain round. Sometimes it will not burn all the way across and I have noticed certain scents it will tunnel. Overall it is not a bad wick. Not sure I would use this in large containers?

Good but…

I’ve been using these for years. The last box of 1,000 had the wick protruding out of the bottom of the metal tab. It made it impossible for the wick to stand even. I had to use my fingernails to flatten out the cotton on the bottom. Wouldn’t be too bad but it adds extra steps, time and physical discomfort when you’re making large quantities.

works well

Works well! But it's out of stock. I am looking for alternative. Does CD 18 is the same as ECO 16...?

Works get wit my containers

These wicks are good I had a little tunneling but not much and the scents are strong as well. I am new to candle making but I’m learning a lot plus I order all my supplies from candle science.

I purchased ECO 16”6 and wanted to know what would be the recommended jars to use for these using 6006 ? I have read some reviews with most saying they are experiencing tunneling & I would love to avoid by going with the right jars. Please let me know thanks
