The wicks I used in my jelly jars were htps. I used mostly htp 73 and htp 83s. But, I found that some of the FOs required htp 62. What I have discovered so far is that some of my spicy scents required the 83 and the lighter oils required the 62 or in between. But every oil is different and some have completely stumped me and I've had to test and test again. I did not realize when I started just how important it is to find the perfect wick, but I really think it makes or breaks the candle. All and all I still love it and this site is perfect for us newbies. There are lots of helpful people who give advice freely. So don't be afraid to ask questions. Maybe one day we can pay it forward, too. P.S. My personal opinion is the HTP wicks for the 4630. I also tried the zinc and they work good, but I think the HTP smoke less. Could just be me, though. Happy candle making!!!:smiley2:
