Metal casting is a 7,000-year-old process used in both manufacturing and fine art. During metal casting, molten metal is transferred from a crucible into a mold to create a positive metal cast object. The metal and mold are cooled, and the metal object is removed and finished. Traditional metal casting techniques include lost-wax casting ...

Before the 18th century, zinc metal could not be made since it melts at 420 o C and boils at about 950 o C, below the temperature needed to reduce zinc oxide with charcoal. In the absence of native zinc, it was necessary to make brass by mixing ground smithsonite ore (calamine) with copper and heating the mixture in a crucible.
