Not very practical or safe since zincs are relatively cheap and the heath
risk is great.

Heating zinc will produce toxic fume that have always be a known to welders
and foundry workers. Even a small amount can be harmful.

I have a lot of old zinc anode remnants from the boat hull hanging
around discards from the annual haulout. Each year I also replace the
anodes in my Yanmar 2qm20 engine, which are tiny, but more expensive
than the much larger tear drop hull anodes.
The engine anodes are just zinc molded on to a thread. Would it
difficult or in any way dangerous to melt an old hull anode down to
refurbish the engine anode?
Thanks
