We all know that ice melts at room temperature, but when placed on a silver strip, the ice melts at a faster rate.Silver will get cold in a few seconds.However, the thermal conductivity of copper is also high.So, you have to confirm the result with another test.
For this you need a nd like (rare-earth magnet).Silver is a metal that does not stick to a magnet.Slowly move the magnet on the silver item.

If the color is dark red, the metal is sterling silver.800 silver is brown and 500 silver is green.The color of brass is dark brown, the color of lead and tin is yellow, and the color of nickel is blue.
