Thank you all for the recommendations. I tried my butane torch, but found I kept burning the wax. I hadn’t considered super gluing the wax on the transfer. That might be something to try. I’ve been getting better with wax, but sometimes I’m still finding my stone popping off after the transfer.
And yes, cutting wax on the girdle facets has been a constant problem… My attempts to clean the wax with a razor knife have resulted in dislodging my stones.
