Step 1: The Materials!
-Two small beakers(50ml, and 250ml)
-Zinc Sulfate, 100g
-Zinc Metal, Mossy, 100g
-Glass Stir Rod
-Copper Pennies, Well Cleaned
Step 2: How To Start Making Silver Pennies!
Fill the small 50 mL beaker with 3/4 full tap water. This is your rinsing beaker. Set aside.
Dissolve 30 grams of Zinc Sulfate in 100 mL of water in the 250 mL beaker. A little heat from setting on the hot plate will hasten this dissolve.
Silver penny turning
Place mossy zinc pieces in the beaker with the zinc sulfate solution, enough pieces to almost cover beaker bottom.
Using tweezers, place two or three cleaned up pennies in step three beaker making sure pennies touch the mossy zinc pieces and are not touching each other.
Bring solution to low boil for about 10 minutes. Your pennies will slowly turn a silver color.
Using tweezers, carefully remove the pennies from the solution, rinse and cool them in small wash beaker then dry them on a paper towel.
Voila! You now have a dandy silver colored penny.
