There are many physical aspects of the yellow metal which are truly amazing. Gold is the most malleable (able to be hammered into very thin sheets) and ductile (able to be drawn into a fine wire) of all metals. It is so malleable that a goldsmith can hammer one ounce of gold into a thin translucent wafer covering more than 100 square feet only five millionths of an inch thick. It would be so thin that 1,000 sheets would be needed to make up the thickness of one newspaper page. Its ductility is equally amazing. One ounce of gold can be drawn into a wire 50 miles long! Furthermore, you only need one ounce of this marvellous metal to plate a thread of copper 1,000 miles long.
