I use a camping gaz stove and various stainless pots for melting and a large stainless spoon as my ladle fitted in a wooden handle.

By far the most important thing missing comment so far is Ventilation.

Lead fumes are toxic, continued exposure causes these toxins to build up and take years for your body to get rid of, if ever. They affect your brain and give a headache that just does not go away.

Dont melt Lead indoors and make sure fumes are not in your direction.

I melt mine in my shed. I wear a face mask fed with air through a flexible hose from outside. And have an extractor fan drawing Lead fumes and carbon monoxide from the burner away from me and outside.

The fine oxides in the air around you can be absorbed by the skin so get changed and shower as soon as possible afterwards.
