From Chemistry Resource Jump to navigation search According to Wikipedia recent Canadian pennies have a composition of 94% steel % nickel % copper plated zinc Pure copper metal is bright and shiny but the oxide is dull Pennies get dull over time because the copper in the pennies slowly reacts with air to form copper oxide This is copper oxide Contents 1 Cleaning pennies; 2
While cleaning iron in vinegar I get a rather pungent iron smell from the mix It takes a lot more iron to harm you than it does zinc so this is only an annoyance BTW an overdose of iron can be injurious No need to panic just be aware More to the point when soapmaking one dissolves lye in water The best approach is to work by weight and use ice for about half the water Otherwise
