I think I may have posted the first time to the wrong area. I am new to this forum. If I did sorry for the double post I recently had to switch jars to my new 4 inch libbey Lucida jar.I am having such trouble getting a good wick for this jar. I hate double wicking so I have tried just about everything else along with double wicking. I have tried 1-HTP1312 , 1-RRD 55, 1-RRD65 , 2x 60-44-18C, 2x HTP 126, 2x HTP 105, 2 xLX16 and 2xRRD 37 . I am at my wits end. I use a 100% soy(Plain 415) wax with approx. 1.50 FO . This has worked for me with my 3.75 inch jars which I can no longer get.Here are my results. RRD55 mushroom quickly RRD65 Mushroom very quickly HTP 1312 not a large enough melt pool after 4 hours 2x 60-44-18C Mushroom and burn very quickly 2xHTP 126 Burns very quickly and gets hot 2xHTP 105 is what I had settled on for the spring and summer . Feed back is after a couple of burn the wicks are drowning out 2 x RRD 37 or 2x LX16 I can see that the same might be happening as the HTP 105 HELP ! with the fall quickly approaching I am freaking out. Do you have any suggestions? I thought the RRD would be the answer to my prayers. Tell me about the CDN Series or anything else you might suggest. Thank you for you help Laura
