I use waxing iron to melt the waxThe pictures look nice. Thanks for sharing.
I tried using similar setup for melting wax in the past and it is messy and too slow. Just set up your waxing iron to be positioned upside down with the iron plate being horizontal. The iron plate surface is a perfect source of heat with the correct temperature control (use the corresponding iron settings) and works much better and faster than heating on gas and using boiling water.
