ECO Candle Wick Dimensions 6in x 20mm
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'm new to candle making, I used the wick guide and recommended wick suggestion and it's perfect. Very happy with my all purchases with Candle Science.

So disappointed!

Have used ECO 10 past yrs without complaints, but last batch is terrible! Wicks mushroom, deosit soot on all containers, & smoke terribly. One candle smoked so much my smoke detectors alarmed. I always trim wick before relighting & the only change is the new batch of wicks. (Many of these were given as Christmas gifts!)

Not performing like they used to

We have been using these wicks in our large 16 oz libbey jars but now after the first burn flame is really low like it’s dissolving the wick and not pushing out the scent. Please advise, has something changed?

last wick i buy

I have tried almost every wick they sell and continue to have pools of wax, tunneling and wick burning out. I just have to do some research and buy from Amazon. Good luck all candle makers.

Mushrooms & smoke

Followed the recommendations for size of container & wax used, but have a lot of trouble with the wicks mushrooming, even after trimming the wicks to 1/4 inch. Lots of black smoke, staining & ruining the containers.

Half & Half

I give these wicks 4 stars. Only because I have used these in several different containers and they all produce different results. Most times the results are ok. I use 464gb soy with 7-10% fragrance oil in each batch. I started off using the 8oz tins, which some would tunnel and some would not. That let me know that it was a PERSONAL error. Which further let me know that I would need to go a size up or continuously test to figure out the exact error. As far as HT and CT, the CT was low but the HT was amazing and smelled great. I then tested the wicks in a cube12oz container. Using only one wick produced tunneling so I doubled the wicks. Melting pool was uneven after 1-2 hours but by the 3rd hour the melting pool was even. I will say that it made the candle burn faster. The HT and CT smelled amazing. My only advice to Candlescience is to give a more accurate guide and not just suggestions on wick size based on size of containers. Candle making is always trial and error no matter how many years you have been making them or whether or not you have a business. Keep testing until you get the required results you are seeking. Best of luck to everyone.

Barns & Burley Candle

I was skeptical at first because of the reviews but I'm glad I gave it a try. I was using CD12's in my 464 per the wick guide suggestion but decided to give this wick a try. I wasn't happy with the larger flame and the deep melt pool I was getting with the CD12. When I first lit the wick I was a little worried because my candle had a sinkhole that I left in it on purpose. I wanted to see how the wick handled itself. I wanted to see if it would continue to burn or put itself out. Luckily it did burn through to a complete melt pool because I had not cut the wick short yet. Because the Eco's tend to curl over a bit, if I would have cut it short then the candle wouldn't have burned properly. I did notice that the scent throw was a little weak at first on the complete burn but once I lit it again to do another burn the throw was just as strong as it was with my CD12 with ALOT less mushrooming. For me, the longer I let it burn the better it seems to behave. The flame does not get as high as the CD12 and it had hardly any mushrooming so that's a plus for me. If you'll let it achieve a full melt pool, which usually takes at least 4 hours because the ECO does not burn as fast, then you should be able to pick up a better scent throw with each burn. Every fragrance oil will behave differently though I would assume. So far I've only tested it in one of my candles but will test them all completely before selling to my customers.

Flame doesn't burn as high and weak scent throw

I've been testing candles for over a year now and I know that ECO 10 wicks alway performed well in my 8oz jars, so I decided to go back to ECO 10 wicks. I've made a few batches of candles with this new wick and if feels like the scent throw is really weak and much smaller. Can someone help?
