To maintain the quality of your bees wax, here's a few things to be aware of when melting:
Heating the wax to tempratures above 85ºC (185ºf) may discolour it. The melting point of beeswax is 62-65ºC (143 - 149ºf). If melted in water at excessive tempratures, hot steam can cause partial saponification and ruin the wax
wax heated in a container made with iron, brass, zinc and copper in it may cause a reaction that will discolour the wax. Stainless steel, aluminum or enameled steel, tempered glass & ceramic pots should be okay.
