Hi everyone,, I have used the J223 and it is a great wax,,,I dont heat my jars or molds in the oven because simply they get to hot when you pour and if you pour to hot, it will cause Bubbles. I zap my jars and molds just a wee bit. you must adjust the temp if you heat your molds or jars.,,,,, The first thing I learned here was " Embrace your wetspots" All candles can get them especially in cool places. If you go into a store you will notice they get them too. It doesnt effect the burn or Scent. Cooling them slowly sometimes helps. HTH,,,
