This was my first group project. We filled a steel bucket with concrete, and placed a steel crucible within, made from pipe. A torch was made using hose from a propane line. We used the torch to heat the crucible, and melted aluminum inside of it. We poured the aluminum into a steel muffin tin to make aluminum "nuggets".
We experimented melting several metals including:
Recyclable aluminum (cans)
Copper (pennies)
Bronze
Aluminum alloy (used for Apple products)
