No, you cannot melt copper with an iron pan. Copper has a melting point of around 1,984°F (1,085°C), while most iron pans are made from cast iron, which has a melting point of approximately 2,100°F (1,150°C).
Since the melting point of iron is higher than that of copper, the iron pan would actually start to melt or become significantly damaged before the copper would reach its melting point. Additionally, household stovetops typically don't generate temperatures high enough to melt either copper or iron.
If you want to melt copper, you would need to use a suitable heat source such as a specialized furnace or a propane torch that can reach the required temperature for melting copper. It's essential to follow proper safety precautions when working with high temperatures and molten metal to avoid any accidents.
