Silver Copper Zinc Tin Alloy AMERICAN ELEMENTS

Zinc was first isolated by Andreas Marggraf in 1746. In its elemental form, zinc has a silver gray appearance. It is brittle at ordinary temperatures but malleable at 100 176;C to 150 176;C. It is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore
