I'm currently testing Titan Wax Natural 5465 Coconut Soy candle wax with ECO candle wicks. I'm hoping that this will be helpful to some when narrowing down which wicks to use.  Feel free to adjust based on your wax/vessel/fragrance oil combo.  I'm using a vessel that's 3-1/8" inner diameter at the top, so if yours is smaller, you will want to wick down.  It's best to test a couple wick sizes in a few wick series or brands to see what you like the best!  Feel free to reach out to me anytime if you have any questions at all.  I'm here to help.

About ECO Wicks...
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.

I'm using a 3-1/8" jar and the wicks I'm using are ECO 10 (single wick), and ECO 12 (single wick).  I'm using Pumpkin Souffle at 9% fragrance load.  I will allow it to cure for 2 weeks before testing them.  I will keep you updated!  The other items I used when testing are the bowtie wick centering bars and our candle wick trimmers.

If you've found a combination that works for you, please feel free to share your results below.

Results

Wax Type	Vessel Size	Wicks	Fragrance Load	Results
Titan Coco Soy 5465	3-1/8"	ECO 10	9% Pumpkin Souffle	Both of these seem too small of a wick.  I'm still keeping an eye on these.  I think both of these are slightly underwicked. I'm going to try ECO 14 & 16.  **There was no soot for this combo but there was a wax layer along the sides of the vessel. I want to try a larger wick to see how that turns out.
