as others have mentioned DOUBLE BOILER only for melting wax.
other safety tips:
- MEDIUM heat only, preferably an ELECTRIC range. There is a veyr high risk of igniting wax vapours when using a GAS stove.
- Devote your entire attention to the melting pot. Do not turn away to go take a piss, or answer the door or phone. ALL eyes on the melting pot. This may seem safety nanny'ish but trust me.........i've seen what melting wax can do fire wise to a structure and a persons body.
- thick leather gloves, LONG sleeve shirt, shoes etc etc etc
- as soon as all the wax is melted, shut off the burner and move both the pot and wax pot together, THEN remove the wax pot and set away from the stove on a hard surface.
- Keep cats, dogs and KIDS away from the room. Cats like to get under our feet and no one feels good dumping hot wax on a little kitty.
