I am sorry Henry, but can't tell you what soy it is as I stopped using soy a long time ago... just now enough throw for me. So this is an old candle. The discussion was trying to single wick a 4" jar, which I've done with a 62 zinc. This 3 1/2" jar was single wicked as well, with a 60 zinc. I now use IGI6006 wax... great throw and good clean burn in this jar. I don't use another type jar, this one is from Fairway Glass and is their 26oz. apothecary.
