I took this from another thread.......this is a lot more informative than what I told you. Once you get the candle made, let it cure before test burning it. With paraffin most people only cure for a couple days or so. But with soy most people wait at least a week, many wait 2 weeks. The basic rule of thumb is to burn 1 hour for each inch of diameter, so if your jar is 2.5" then you want to burn it for 2.5 hours. It should achieve a full side to side melt pool in that time and be giving off a good scent throw for a reasonably sized room. If it isn't getting a good melt pool and is leaving wax around the edges, chances are you need a bigger wick. That's when the fun begins... time to start over and try again with another wick! Don't forget to document your testing, write down how long you burned it for, what size room you burned it in, how well the scent throws, etc. I have a testing worksheet here that might help. Once you get it burning and throwing good, give a few to friends to test for you and get their feedback too. The best way to learn is just to try it once and then come back with questions. Get your feet wet and then you'll have a better idea where to go from there. HTH!
