Rcandles Posted April 21, 2021 Share Posted April 21, 2021 I just changed my jar size to 16 oz straight sided flint. Opening is 31/2 inches. I used 4630 paraffin wax and tried htp105 and that left 1/4 of wax on the side after 3 hrs. of burning. I also tried cd-22, 62-52-18 and a 66-44-18. Any help will be very helpful and appreciated.

TallTayl Posted April 21, 2021 Share Posted April 21, 2021 Don’t go by first burn. Too much changes in subsequent burns. By the time you hit the middle shocking changes in air current happen and can cause dramatic heat increases and flame height length. Quote Link to comment Share on other sites More sharing options...
bfroberts Posted April 21, 2021 Share Posted April 21, 2021 You won't get a full melt pool on the first burn with that jar unless you over-wick it. One of the larger zincs should work relatively well. It's not very pretty at first, but once the candle has had a week or two to cure it will burn better. You can also double wick with 2 small zinc wicks. LX wicks work well in 4630 too. The wick guide at Candle Science can give you a starting point.
