Just poured my first 4 palm wax candles. I heated the wax to 200 then poured into containers at 186. They just started cooling down. I did preheat the libbey 11oz jars. 2 questions. Do I need to poke holes in top at certain point? About how long after cooldown? Do I need to flip jars over at some point. Think I read somewhere that people do that to fix the wick or some such thing of air that is trapped? Thanks
