Stop in for a cup of coffee

Heres the deal My SIL is working for a graveyard company. They have a few thousand bronze placks that were wrong somehow. Any how they just can scrap them as is Privacy issues. so they have to be melted down to scrap. Any ideas?

Melting point of like 1700°F.

Need a forge furnace. If the plaques are large then that's a challenge
