Testing seems to be a big PITA, especially when you get on these boards and the front page is half-full of people asking what went wrong when they were testing, or if someone else has had issues burning a specific FO. This is where this community really shines and have helped me more than they really know. When I started out making candles, I was using Hobby Lobby wax, cheap wick, cheap FO, cheap color and let me tell you, when I came on here and saw just how much more it is to it then that, it strengthened my resolve. For the last three years, I've used IGI-1218 because I liked working with it a lot. Then when I came back after a year and I'm getting geared up to start them again, I decided to switch to 1343. Candleman and a few others have used this wax and I PM'd him to find out how he felt about it and if he could give me a few tips. His tips, needless to say, involved wick that I've actually never used in 1218, so there will be a massive amount of testing involved. As Top said, it's personal preference as to how you want your candles to burn and I know that Candleman's tips were his personal preferences. I'll use his tips as guidelines, but that's it. My first wax shipment is due in Wednesday and it's an entire case of 1343 with several wick samples and FOs to get me re-started again. As I find the right formula for each FO, I'll write it down, burn another one for safe measure and then move to the next. I can tell you now, about 75% of that case will go to nothing but testing and as far as I'm concerned, it's a good, sound investment because I'll know I'm producing a great candle that burns safely. I've also not sold any of my candles SERIOUSLY and I've been working at doing that now for about three years. I want everything in order and ready to go before I even consider that and while a few people here may think that's crazy, if you stop to think about the amount of testing that's involved, the amount of tweaking a formula here, or shoving a wick in there, I think I'm right on schedule when I say I'm slated to begin selling them sometime next year. Four years of testing, I think is right for me.
