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.

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


I bought these wicks based on a recommendation. I have tunneling in my 12 oz jar. I use 464 wax and usually the CD wicks but my Hot scent throw wasn’t as good as I would like. Anyone have a better option because these wicks aren’t cutting it.

Hi! A member of our team will be reaching out shortly!

Candle Diameter Its good for?

What is the diameter of the wick and what are the recommendations for the diameter of the candle it can fit in? Another comment said she still has tunneling its a 3.3 diameter candle so i assume smaller.

ECO 16 in 8oz tins getting tunneling

We have been using these wicks since we started in 2015. This last batch of wicks we used in our 8oz travel tins and we are now getting tunneling. We have gotten this feedback from several customers and tested out ourselves. There isn’t the option of a larger wick so we may have to find another alternative.

Help please

Are these good for paraffin wax candles in 8 ounce jelly jars I’m experiencing tunneling and I’m trying to find the right wicks

These work decently in our soy/paraffin candles...IF we don't use any dye at all and use a small container. Unfortunately, many of our candles are lightly dyed and our favorite container is the 12oz status jar. I have been testing several wicks to go best with not only our wax blend but also our container of choice, and what we have found is that the ECO 16 wick simply doesn't work well with this particular container. Not only is there mushrooming, but there is soot, tunneling, and an uncomfortably high, wild flame. If you are thinking of trying this wick for a smaller container for a candle without any color, you should have pleasant results, but if you are searching for a match for the 12oz status jar, keep looking.


Not working

My jar is 16 ounces. The diameter is 3.32 and I picked the eco 16. I am still experiencing tunneling? Does anyone have any advice ? Should I try a different type of wick?

As expected

Works perfect for my mason jar, soy candles!


Soy Candle

These wick works well with my pure soy wax candles. I have used it with both colored soy wax and uncolored soy wax, and it still works well for me. I always love to order from Candle Science. Their products are great quality.

Love these wicks! I use the tumbler jars, and they're awesome.
Friendly reminder for those saying this wick was too big or too small when they followed candle science reccomendations, your wick size will vary depending on how heavy your fragrance load is, and if you're using dye.
People who use my jar have found great results with eco 14 but I have to wick up to 16 because of my dye.

Best Wicks!

I used 12 oz status jars and 464 wax to make my candles. These are the only wicks I use and they burn evenly, would recommend! Not sure what other reviewers did wrong, but I use these only and love them!


eco 16 wick

I tested eco 16 wick in an 8 oz. tin container and it had a good melt pool after 2 hrs. CS recommended wick eco 14 but it tunneled in my tins and that is why I chose to try this wick. Works very well.


Work great

After doing many candle burn test, discover that this wick works great with soy wax. The key is to test, test, and test. I love to use 464 wax and 444 wax (another great product).


Very Consistent

We've used them for years. Always consistent. Use thousands of em every year.

I posted a review on the 13th and gave these wicks a less than favorable review. Operator error. I had read somewhere that it was ok to use crayons as coloring... NOT SO. Not in soy wax anyway and if so, use very little. I know crayons have a higher melting point which the wick was not designed to melt. I am burning a candle I poured yesterday using GW 415 and these ECO 16 wicks with no coloring and has fragrance. It is burning beautifully! Wanted to make things right here. Sorry for posting the negative review.


Not happy..

What is wrong with these wicks? Tunneling badly. It's like they're burning too quickly and then going out altogether. Very poor quality I guess.


ECO 16 is Not burned correctly

Recently purchased ECO 16 for 3 1/4" diameter glass jar of Golden Soy Wax 464.
I constantly use ECO wicks for all my soy candles , but this order of ECO 16 has poor quality.
A flame on ECO 16 wick turned off itself every time I tested and caused "Tunnel Effect" . Quality on ECO 16 is uncertain, but other sized of ECO wicks are OK.


Works Great on 8 oz. Jar

The wick was recommended by their Wick Chart and it worked great on my 8 oz. The burn was perfect, but to my taste I think a double wick would be cute! I am hoping to double wick my 16 oz (to use these on 8 oz) and the chart recommends ECO 10 6" Pretabbed Wick so I am looking forward to a great burn by those too!
