Students participate in a bronze pour, where molten metal temperatures reach 2,000 degrees. The lost-wax casting process is more than pouring metal, though. Dating to ancient civilizations, a wax model of what will be cast in bronze is covered in a mold, called a ceramic shell. The mold is heated, allowing the wax to melt out, leaving a void for the bronze to be poured later.
