I received my 12 sided jars a few days ago and I love the way they look. However my 12oz I am having trouble finding the right zinc wick. I am using J50 with 1oz blueberry cheesecake per pound. I used a 51 and I did not get a good melt pool it sort of tunnelled but throw was nice. Then I used a 44-28-18 and I got a better melt but took 4 hours to get but leaving slight residue on sides of glass. Is there one in between these two. What else can I do? I really love the zinc wicks with the J50. I need help quick because I have orders for this particular jar within the next two weeks.
