This is where I am . The CD6 way to small. Not at first but then they are. CD7 too small not at first but then they are. I still have one going. The CD8 leave a layer of soot every so many burns and then they look too small. I am pouring 10 lbs of wax today to make 2 candles of Tulip, watermelon, honeysuckle ,heather and lilac. I used 2.3 oz of FO for each 2 pounds of wax That is I beleive a smig over 7%. I am going to let them sit for a couple of days while I and hopefully you all decide what i should try next. I have CD, CDN CSN and some ecos ( not sure of sizes at the moment) on the way . I also have some HTP83 which I think are too small . Thanks guys.
