Silver | Mineral Monday
Pure silver is a beautiful metal with a brilliant white luster. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide or air containing sulfur. It is slightly harder than gold but still very ductile and malleable. The only more ductile metals are gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals and the lowest contact resistance.
