Silver


Silver, like gold is a very valuable metal that people use for jewelry.

It is the best metal at letting electricity go through it, and letting heat pass through it.
Silver is also sometimes used in teeth to fill in areas where dentists drilled out parts of teeth.

Unlike gold, silver does need to be polished to stay shiny. When silver gets dirty it is called getting tarnished.
