Of the four, gold is the most malleable, capable of being beaten into sheets so thin that they can actually transmit light.
Malleable rocks are rocks that can be easily shaped or molded without breaking. They tend to be softer and more pliable than harder, more brittle rocks. Examples of malleable rocks include talc and soapstone.
Common minerals that meet these criteria include gypsum, fluorite, and talc. These minerals are generally dull in luster, not malleable or ductile, and are non-conductive of electricity.
