Background: IGI 4630 (Harmony Blend), HTP pre-tabbed wicks from Peak, 4 oz jelly jars FO at 6%. OK-on some of my tests, the burn starts out good. Quarter-inch melt, some hangup which later catches up. Great throw. But when the burn gets down to less than 1/2 inch of wax, the wick tilts over and gets long and then the flame becomes unacceptable large. (If the wick does not tilt, it curls and self-trims so no flame problem. ) I know, the wisdom says stop burning the candle at 1/2 inch. But this is a small jar and I know the customers will burn it until the wick tab puts it out so that is how I am testing the candles. My theory now is that the wick tilts because it is bent when it is stuffed in the bag and the high-melt wax is broken. Has anyone else had this experience and how do you handle it? BTW, the test jars were not preheated but I normally preheat my jars in the oven at 150 degrees, more or less (it is an old oven). I notice my Snowtop samples were carefully packed and not bent at the tab but they don't sell small enough sizes. Thanks!
