Kevin I finally listened in to your pod cast-after my friend told me about your review of the EAS class on wax. First off, thanks so much for your efforts with this podcast and all the organization around it! I was so happy to hear how much you enjoyed the wax class. It was part of a special day I organized on Excellence in Honey and Hive Products and in fact, Bob will be teaching a workshop in a few weeks up here with live demonstrations and actual candle making. I did want to share that he does in fact use metal molds too- the taper metal molds and he uses a special tool to carve out the bottom. Take care and best of luck in beekeeping.
