Re: Bumpy top of candle
My limited understanding is that cooling too fast is what causes what you see. That, and moving the mold after the pour. The easiest way to combat this is to make sure the wax is at the proper pouring temperature and to protect the molds from cool air currents. You could also try short filling the mold, and then do a top off pour once the wax is mostly solidified. My molds pour so the bottom is up and the uneveness is removed by rubbing on a hot surface.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
