I purchased the ECO 12 wicks to burn test in small container 2.5" in diameter. Coconut/Soy 464 Blend 6% FO. Candle is tunneling and it's been burning for 3+ hours. I used the wick guide recommendation. I did read lab notes and maybe I'm confused. But this wick seems very thick for this size container so I'm at a loss. I tried a CD 6 which gave a great melt pool and did reach sides of container but left some wax on the sides of the container. Help :/

Help! I purchased this on wick guide recommendation for my small container (2.35'' diameter) candle using cocosoy wax - I tested it on a couple of different scents, and both produce a large flame and smokiness...to the point that it's difficult to smell the scent behind the smoke. What wick should I be using instead?! Would the CD or LX series be any better? I've also read good things about the HPSP wicks.

I love these wicks! I have been using this wick size for a year now with 464 soy wax . I double wick my 8 oz. Apothecary candles, awesome heat throw, even burn, no soot issues with my candles. I even use these wicks for my 22 oz. Three wick candles and my candles are perfect every time. No customer issues or complaints! Thank you Candle Science!

I picked the wick using the guide and it doesn't burn evenly, and the smoke at the end is concerning. I ordered more thinking they were correct and now I don't know what to do.

If you burn a candle more than the recommended time, even the correct wick size could result in tunneling. Therefore, I like to include a reminder to my clients to burn 2-4 hours at a time.

I have used only Candle Science’s ECO wicks for over four years. I burn multiple candles daily and haven’t had problems or customers report issues. Depending on the fragrance oil, ECO 12, 14 and 16 work perfectly in 9oz (medium) straight-sided glass jars. I use GB soy wax 444 with the maximum fragrance load. This always produces incredible hot throws! I perform a wick test for every fragrance before making a new scent combination available. In the beginning, I wasted a lot of wax and oils by creating entire batches with the test candle. Now, I make one test candle at a time with the jar a little over 1/2 to 3/4 full. This saves a lot of money! I’m able to clean out and reuse the test jars.

I am a beginner, so it could be me. I followed the guide to wicks, scaled the wax and fragrance according to the guides. Made several candles for gifts and having tunneling issues as well.

Every candle I made with these wicks has tunneled. They were small 4oz candles too. Do not recommend.

I used these in my 8oz temperature resistant jars with soy wax and about a 10% fragrance load.
They work great, I burned my candle in two hour increments for two days to see how the wick would perform.
I didn't get any tunneling, mushrooming or soot after burning for two hours each day at a time.
However, I decided to burn my candle longer than four hours with a watchful eye.
I wanted to see what would happen if someone doesn't know to burn the candle only four hours max and of they didn't know to trim the wick....
I burned the candle for eight hours.
Yes eight consecutive hours! My candle burned great and at the 8hour mark some soot started to occur.
I simply blew out the candle and wiped the soot away.
Great wicks. I hope this review helps someone.

Disregard the review below! These wicks did not come from candle science. I just received my wicks from them and they are burning perfect.
