Pre-heat Your Jars

Pre-heating the Jars
David Fisher
One thing that everyone who makes container candles in clear glass jars battles is "wet spots." They're actually not "wet", it's just a place where part of the wax has separated from the jar, and part is still sticking. There is no way to completely prevent them, but one way to minimize them is to pre-heat your jars. If you're just making one or two, you can zap them with the heat gun. If you're making more than that, just put the jars on a cookie sheet and place them into a lightly warm oven - about 150 degrees is just right - warm enough to heat the jars, cool enough to not melt the wicks.
