"Silver has the highest thermal conductivity of any common metal or alloy," explains Martin. "Even at room temperature, authentic silver products will melt the ice at an exceedingly rapid rate.

What happens if you put ice on silver?

Silver is a good thermal conductor. So if you put an ice cube on top of your silver item, then the ice cube will start to melt quickly. An ice cube placed on silver will melt quicker than on iron and a little quicker than on copper.

What metal melts ice?

The results for the overall average for the metals' thermal conductivity were that copper melted the ice the fastest followed by zinc, brass, aluminum, and steel.
