Please someone let me know if some sooting on the rim of a candle jar at a mid burn(several burn tests) after 5 +hour test burning is considered acceptable and safe? I'm new to candle making, and trying to adhere to 100% to ASTM standards, but are these standards realistic? I have tried every wick/size type for 6006, and 4627, they either smoke, I fail them, tunnel, fail them, or soot after several days 4+ hour test burns,(fail) and then I'm just depressed, and feel like I'll  never make a candle that doesn't soot or wick down and sadly tunnel. I use Filmore's 12.oz straight sided salsa jars with diameter of exactly 2 15/16s, just under 3inches diameter by 3.19 tal, 3.38 outer diameter l(short &fat), and I cannot find a perfect wick size for these jars. I follow the mfg instructions on temperature melt, blend, pour, and cure, so yes, this is sooting driving me a little crazy🤯🤪
