Technically, it is possible to melt copper in a wood stove, but it's not a practical or recommended method for several reasons.
Temperature: Wood stoves typically do not reach the extremely high temperatures required to melt copper. Copper has a melting point of around 1,984°F (1,085°C), which is well beyond the temperature that a standard wood stove can achieve. Wood stoves are designed for heating and combustion, not for reaching the temperatures needed to melt metals like copper.
Safety: Attempting to melt copper in a wood stove can be extremely hazardous. The high temperatures and melting metal can cause a risk of fire, and the fumes produced during the process can be harmful if not adequately ventilated.
Damage to the stove: Melting metal in a wood stove can cause serious damage to the stove itself. The intense heat and molten copper can warp or crack the stove, rendering it unsafe and unusable for its intended purpose.
If you have a need to melt copper or any other metal, it's essential to use the appropriate equipment designed for the task. For melting copper, you would typically use a furnace or crucible specifically designed to withstand high temperatures and safely contain the molten metal. Additionally, proper safety measures, including ventilation and protective gear, should always be followed when working with high temperatures and molten metals.
