Hey guys, just thought I would jump in here. I use 6006, 6% fragrance oil and zinc wicks. In an 8oz jelly jar I usually use a 51z ...I pour a lot of bakery scents (vanilla/spice). In an 8oz square mason jar or 16oz mason jar, I usually use a 60z. I've tried other wicks with 6006, but zincs work the best for me. I keep my wicks trimmed at 1/8" instead of 1/4" and that solves the problem of smoking. However, I do get mushrooms, but my customers don't mind. I do get frustrated with 6006 because of sink-holes near the wick; I usually have to use my heat gun. I also think 6006 is finicky because I have to cover my jars and let them cool slowly to avoid (as much as possible) wet spots. However, it's the best parasoy wax that I've used so far. I've seriously considered changing my wax to Candlewic's CBL-130, but I hate to have to go through all that testing again.
