About the ECO Series

Sooting and mushrooming

Hi I’m having sooting and mushrooming when I use this size wick do I need to go up or down a wick size to provide right burn for my candles?

Heavy Sooting

I wanted to write a nice review but I can't.. just like some of the other reviews I chose the wick recommend for the jar and it has been a problem for me with sooting and mushrooming. I'm really sad about it because I really wanted to start my candle journey this year.

Works great

I’ve had great success with these wicks. I double wick my 13 oz jars that have a 3.5” diameter, use GB 464 soy wax and found that they burn great!

Works great with soy in tins

We have been using these wicks for years in the Golden 464 and the "original" Eco soy waxes, and they seem to work great. We use them in 4 oz tins and also straight 8 oz mason jars with no issues, no tunneling or smoke. We use 1 oz FO/# wax. Wish they were in stock more often. The 1000 pc bag is most economical, but you probably lose about 2% by the time you get down to the bottom of the bag there are usually some that have just been too bent or banged up to work at all. They stay in place well when pouring - we sometimes don't even need to use a wick holder. Overall we are very happy with them and recommend.

Perfect Wick!

I love this wick! It works perfectly for me in the size jars and with the wax that I use! Hopefully they will get more in soon!

Mushrooming and Sooting

These were recommended based on the vessel and wax I chose. Even with frequent trimming, the wick mushrooms and has sooting/flickering. Please help!

Out of Stock

These wicks work well but why are these wicks always out of stock?



These burn excellent for us in your tumblers. The reviews are shocking, but after many tests, we find they are consistent! We do include a Candle Care card with each candle with common sense steps of "Trim wick after each use, keep wick 1/4 inch" ...etc. These wicks burn well, but the end will "bloom" after a long burn and the customer must pluck/trim/cut that mushroom off before relighting (a "duh", but some people do not know that). Our candles burn down the sides every single time. We use ECO 8 for 3" tumblers and ECO 2 for smaller vessels.


I am having major issues with this. Not sure if it's the wick or if I am doing something wrong but I am following instructions 100% I am using the Libby jar and bought 2000 of these recommended wicks using one causes tunneling. So I added two in each jar and that gives me a better melt pool. However, there is barely any scent throw when the candle is burning and I am using 9-10% fragrance oil, pouring it into the wax at 185f.. all soy wax & waited 1 week for it to cure. I've used wicks from amazon just for testing scent throw (they weren't the right size and quality was not good) however, was able to get a scent throw using them. So please advise does this wick affect my candle? I bought 2000 trusting it would be great for my jars.

Perfect wicks for 4oz jelly jars

Amazing and slow burn giving the perfect candle for a 4oz jar


Work great

I use an 8oz straight sided jar, just under 3 in diameter, with a custom mix of soy and coconut with an eco 8 wick. They work great for me. The coconut wax can be sticky to the wall however, as others have said, by the time it has burned halfway it melts all the wax off the side of the jar. I burn for a minimum of 2 hours 3 is preferable.


They work just fine.. I think

I see a lot of bad reviews for these wicks. I am using them for the straight sided tumbler jars. I have a soy wax blend. I have not experienced any tunneling. It takes a while to get a full melt pool but i find that in 3 hours it’s fine. My only issue is that I do get black soot sometimes. I’m very intentional with where I’m placing my candles. (Away from drafts, windows, etc) so I’m not sure why the black soot happens. Another thing I’m noticing is that if I trim the wick to about 1/8 inch instead of 1/4 it burns better. Idk. I think it’s working. I’m willing to keep giving them a chance.

Working great for me

I see a lot of comments giving these wicks bad reviews, and I wanted to give some advice that I saw which I found helpful. If a little bit of wax is left on the sides after a test burn, like if it doesn’t melt all the way to the edges, it doesn’t necessarily mean it’s the wrong size or ‘tunneling.’ It’s better to judge a wick when the candle gets to about the middle point. Usually at this point, the wax that was left on the sides will begin to melt, giving the candle a more even appearance. Some people do wick testing by filling up the jar only half way, so as to not waste as much wax and FO. Hope this helps! The candlemaking thread on is a great place to ask questions from other candle makers and get advice.


Why is this wick recommended for the Straight Sided Tumbler (Libbey)? 0 stars, do not recommend
My candles are tunneling. These were the candles I was looking to start my own business with, what a waste. Very upsetting.

Karina Ehrman

I tried to use all the wicks as suggested and I also have issues with them. I find that if I use 2 wicks in each candle then they burn a little better, but I don’t want to use 2 wicks in each candle. I have 4oz Tin’s, 8oz, 12oz frosted and un frosted!! I have used so much wax on trying to get the wicks correct!! The wick guide is not very useful...

SM Parker

I bought these to use with the straight sided tumbler jars and almost every single candle has experienced tunneling. I’m a little disappointed that these are recommended for these jars. I am going to try to wick up. I would highly recommend that you do a test candle before using these.

Kyla Demski

I have a question...

Wud u recommend this type of wick in a pint size Mason jar(16 oz)?? Thank u!!

Hi! Wicks depend greatly on the specific type of wax being used. Be sure to check out our wick guide to get a recommendation for the best wick to start your testing with for your containers and wax combination!

Not happy with these for the libbey straight sided jar

I poured 8 pounds of wax using these wicks for the libbey straight sided jars just as reccomend for the jars. I decided today to test one since I have a few first time orders coming in and the wicks are definitely not the size for the jar I'm using. I did use 9% scent load so I'm not sure if this is the reason or what, but now I'm have to go back and clean my jars to redo, and hopefully since they were labeled I can reuse them. I also did not like the black smoke no matter what I tried. This is a major setback as I'm pushing for time to fit this in with my fulltime job. Other than this issue, I love all other products by CandleScience so far.


Slightly disappointed.

I recently ordered the Eco 8 wick because it was suggested to go along with the straight sided tumbler, however when I tried it I experienced tunneling. I am rather disappointed. This is the second wick that was suggested that I’ve experienced this issue with.

Great burning wick!

I use these wicks with a blended soy wax combination and 8.5% scent load! They burn perfect for me! Its a nice clean wick!

True North Candle Company

I have been using these wicks on my 8, 12, and 16 oz mason jar candles with 464 wax and they burn so perfectly I’m in nirvana. I had used other wicks in the past from the woman that was exiting her wholesale soy candle business, but I found they were nasty and mushroomed a lot. This is not the case with the Eco 8, it’s a perfect clean burn for many sized mason jars.


Not Happy

I purchased these wicks because they were supposed to be the ones that would work in apothecary jars and I double wicked them, but the wicks burn out before the candle does. I am glad I tested them before I made a bunch of unsellable candles. I use EcoSoya Advanced wax and I'm not sure what I am going to do about the wicks now!

Hello, and thank you for sending in your feedback. While our wick guide is a great way to get a jump on testing, the wick size may need to be adjusted depending on your exact formula and environmental conditions. We always encourage thorough testing to ensure the best fit for your candles, but we'd be happy to offer feedback on your testing. Feel free to reach out to our support team and we'll do our best to help you find the perfect wick!

Candle Company Owner

I am so sadly disappointed in these wicks. I used to buy this exact wick from another company, and they worked perfectly! Since I buy many lovely scents from CS, I thought I'd just buy them through them. Unfortunately, the wicks, like others have said, do not burn correctly. The wax pool overwhelms them and the pool does not get all the way across. Alas, I'm hoping I haven't lost too many customers. I didn't realize there was a problem until one of my customers spoke up. Now, I'm devastated and hope others will speak up and give me another chance to fix this blunder. Am going back to my old company. Still love your scents, CS, but these wicks are not up to snuff.

CandleScience Reply

Hello! Thank you for reaching out to us. Burn issues will often appear to be wick-related, even though they may stem from other factors. Variations in wax and/or fragrance oil, as well as environmental factors and burning practices, can have a large impact on the way that a candle burns. Wicks tend to be a consistent component, but we'd be happy to discuss it further and make sure they are up to standard. Feel free to reach out to our support team and we'll help in any way that we can!


Ok... I originally gave 5 stars prior to me testing several candles. The wick burned out faster than the candle itself.
Maybe because of the low tureen glass jars (3oz), not sure, but I am sure I am stuck with 20 candles that are not sellable. Not happy.


Slow Burn

First I’d like to say I understand some of the mixed reviews about these wicks. Barely any flame, etc.
After my testing the wick I found yes, it’s a very low flame, and a slow burn. I’m still getting a beautiful hot throw, but more importantly .....the candle is lasting longer because of this. I have been burning a 3oz glass Tureen jar purchased here at Candle Science for 2 days , about 4 hours each day and the wax is barely at a 1/4 of the candle melted. My customers are going to love how long the candle lasts along with additional burning time. And you know what this means everyone? You can charge more $ cause you know you have made a lasting candle! YIPPEE!
Thank you Candle Science!
